AccessPublic TypeDiscussion Public Content Information At the April 18, 2017 Village Board meeting, a contract was awarded to Christopher B. Burke Engineering, Ltd. (CBBEL) to conduct a Phase 1 engineering study for improvements to the closely spaced, high volume intersections at the confluence of Rand Road, Central Road, and Mount Prospect Road. Attachment A contains a map depicting the area. For many years, these intersections have been characterized as problematic for motorists. Notably, the area has been plagued by lengthy delays, long vehicle queues, blocked intersections, vehicle crashes, and generally poor driver behavior. These intersections are largely controlled by the Illinois Department of Transportation (IDOT) with the exception of the Mount Prospect Road approaches to Central Road and Rand Road. The section of Mount Prospect Road near these intersections is owned and maintained by the Village of Mount Prospect. Over the years, IDOT and Village staff have attempted to mitigate these problems by modifying traffic signal timing and limiting vehicle movements. Unfortunately, these conventional, rudimentary corrections have not proven effective. For its part, IDOT recognizes the intersections are inefficient and spawn driver ire. However, the collective problems have not spurned the agency to action. Presently, IDOT is indolent about these intersections and has no near term plans to construct improvements. To provide a catalyst for action, the Village has elected to complete a Phase 1 engineering study of the area. A Phase 1 study is a proven, formulaic engineering design process that involves inventorying existing conditions, soliciting stakeholder input, developing and evaluating alternatives, and ultimately identifying a preferred solution. The capstone deliverable of this study will be a Project Development Report (PDR). When complete, this report will be submitted to IDOT for concurrence and approval. An IDOT sanctioned Phase 1 Study PDR will improve Village (an IDOT) eligibility for federal funding to design and construct preferred improvements. CBBEL has made substantial progress on many key components of the study including solicitation of stakeholder input and development of alternative solutions. Attachment B is a summary of an initial stakeholder open house held on August 10 of last year. Attachment C is an evaluation of several alternative solutions. The next steps of the project will include finalizing stakeholder input, defining a preferred alternative(s), conducting a second stakeholder open house, completing the PDR, and submitting final documents to IDOT. Staff expects that the project will be completed, including IDOT review, by the end of 2018. CBBEL engineers and Village staff will make a short presentation of this information and facilitate discussion. Staff seeks Village Board input regarding evaluation of alternative solutions. https://www.boarddocs.com/il/vomp/Board.nsf/Private?open&login6/22/2018 BoardDocs® ProPage 2 of 2 Alternatives 1.

Building on the planning efforts summarized in the Rand Road Corridor Plan (RRCP), the Rand -Central -Mount Prospect Road Intersections preliminary engineering and environmental study takes a fresh look at the study area to determine an improvement plan that addresses traffic deficiencies related to congestion, mobility, access, safety, and pedestrian/ bicycle accommodations. Some of the reoccurring concerns heard are that long back-ups at the intersections cause blocked intersections, poor vehicular mobility, and access issues to and from adjacent businesses and restaurants. In addition, congestion causes erratic driver behavior with associated safety concerns and pedestrian/ bicycle accessibility concerns. Based on data collection, crash analysis, existing and projected year 2040 traffic analyses, public feedback received at the Public Information Meeting in August and through the online questionnaire, and with the interim improvement at Central and Mount Prospect Road intersection incorporated, a full range of alternatives was developed to address identified transportation issues within the study area. The Public Information Meeting summary is Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page I i Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report included in Appendix 4. The following Build Alternatives were identified for the comparative evaluation- • Alternative 1- Add Auxiliary Lanes on Mount Prospect Road at Central Road and on Central Road at Rand Road • Alternative 2- Modify Plaza Main Exit to Southbound Right -Out Only • Alternative 213: Alternative 2 plus Add New Traffic Signal at SE Plaza Access Drive • Alternative 2C: Alternative 2B plus Add Dual Left Turn Lanes on Rand at Central in both directions • Alternative 2D: Alternative 2B with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 2E: Alternative 2C with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 3- Relocate Main Plaza Exit/Entrance • Alternative 313: Alternative 3 plus Add New Traffic Signal at SE Plaza Access Drive • Alternative 3C: Alternative 3B plus Add Dual Left Turn Lanes on Rand at Central in both directions • Alternative 3D: Closely Spaced Intersection Concept with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 3E: Alternative 3 with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 3F: Alternative 3C with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 4- No Left Turns at Rand and Central Intersection • Alternative 5- Grade Separation at Rand and Central Intersection • Alternative 6- Modern Roundabout A concept drawing of each alternative is provided in Appendix 1. Evaluation Approach To comparatively evaluate the range of alternatives, an alternative evaluation table was developed and is included in Appendix 2. Alternatives were compared to baseline conditions (Central/Mount Prospect Improvement with year 2040 traffic volumes) using several evaluation criteria to demonstrate how well project needs are met, most notably- • Mobility/Access: Reduce the overall study area total delay and travel time, and reduce arterial travel times through the corridor. • Remove Blocked Intersections- Reduce queuing through upstream signals and overall length of queuing. • Safety- Improve signalized intersections level of service and reduce average delay because reducing intersection queuing and congestion improves safety. • Planning Level Construction Cost Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page I ii Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report Existing and year 2040 traffic volumes are provided in Appendix 3 Summary of Results In comparison to the baseline condition (2040 with Central/Mount Prospect Improvement), Alternatives 4, 5, and 6 would not provide overall traffic operations improvements, and had the highest estimated construction cost of all alternatives considered. On this basis, these alternatives were considered but are not recommended to be considered further because they provided limited benefit when compared to their high cost and impacts. Alternatives 1, 2, and 3 and their variations remain under consideration and are being further coordinated with project stakeholders. Alternative 3 would provide the lowest evening rush hour total delay and travel time compared to the baseline condition for all alternatives with relatively low impacts and cost. Alternatives 1 and 2 also provide improvements over the baseline condition with relatively low impacts and cost. Alternatives 1, 2, and 3 were discussed with the Mount Prospect Plaza managing company (i.e.; RAMCO) on March 14, 2018, and the meeting summary is included in Appendix 4. RAMCO expressed support for Alternative 2 as it includes the channelization (adding right and left turn lanes) improvements proposed by Alternative 3, but converts the Plaza exit to a right -out only. RAMCO indicated that Alternative 3, which relocates the Plaza entrance/exit presents many challenges as the access is stipulated via separate leases for each store within the Plaza. If Alternative 3 is chosen, a condemnation process may be necessary based on all the required agreements between parties. RAMCO also requested a traffic signal at the southeast Plaza entrance to improve internal Plaza circulation and balance the loss of the through/ left turn lane at the Mount Prospect Road exit, which is Alternative 2B. Alternatives 3D, 3E, and 3F were developed to further investigate a key concern of completely removing blocked intersections at the Rand -Central -Mount Prospect intersection triangle. Alternatives 3D, 3E, and 3F are not recommended as optimizing the traffic signal timing to clear blocked intersections results in longer clearance intervals which create a longer cycle length and additional delay. Similarly, Alternative 2C and 2D were developed to investigate revising timings to remove blocked intersections from Alternative 2B and 2C, respectively. These performed much better than the Alternative 3 variations described above in that the Alternative 2D total delay and travel time is similar to baseline conditions and Alternative 2E reduces total delay and travel time over baseline conditions with the added benefit of removing the potential for blocked intersections at the triangle with the longer clearance intervals. Next Steps Further coordination of Alternatives 1, 2, 2B, 2C, 2D, 3, 3B, and 3C in consideration of the input received from the Mount Prospect Plaza management company, is planned with Walmart, the Cook County Division of Transportation and Highways (CCDOTH), the City of Des Plaines, IDOT, and FHWA. Based on this coordination, the finalist alternative(s) will be Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page I iii Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report identified, further developed to a concept plan stage, and will be presented at a second Public Information Meeting for all project stakeholders (motorists, residents, businesses) to have an opportunity to review and comment on the overall alternatives evaluation process and results, and to offer comments on the preliminary concept design for the finalist alternative(s) presented. Public Information Meeting #2 is anticipated in mid -Summer. Subsequent to the Public Information Meeting #2, the preferred alternative will be identified, with detailed engineering plans and studies developed and coordinated with IDOT and FHWA for review and approval of the Phase I Study. Completion of the Phase I Study is anticipated by the end of 2018 or early 2019. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page I iv Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report I. Introduction Previously, the Rand Road Corridor Plan (RRCP) was jointly funded and completed by the Regional Transportation Authority (RTA) and the Village of Mount Prospect in early 2017 as a feasibility study of general improvement needs and priorities along the Rand Road corridor from Camp McDonald Road to Central Road. The RRCP provided a framework for near-term and long-term improvement priorities, and identified the Rand -Central -Mount Prospect Road Intersections as a near-term improvement priority. Building on the planning efforts summarized in the RRCP, the Rand -Central -Mount Prospect Road Intersections preliminary engineering and environmental study (Phase I Study) takes a fresh look at the study area to determine an improvement plan that addresses traffic deficiencies related to congestion, mobility, access, safety, and pedestrian/ bicycle accommodations. Some of the reoccurring concerns heard are that long back-ups at the intersections cause poor vehicular mobility and access to and from adjacent businesses and restaurants. In addition, congestion causes erratic driver behavior with associated safety concerns and pedestrian/ bicycle accessibility concerns. The purpose of this report is to provide a comparative evaluation of the range of alternatives for the Rand -Central -Mount Prospect Road Intersections Phase I Study. Based on existing and projected year 2040 no -build safety and traffic analyses, and public feedback received at the Public Information Meeting and through the online questionnaire, a full range of alternatives was developed to address transportation issues within the study area. Project goals include reducing delay and queues through the intersection, improving access to and from adjacent commercial and residential areas, and upgrading pedestrian/bicycle accommodation near the triangle intersections. The concept range of alternatives were formulated and discussed with Village of Mount Prospect (Village) staff in September 2017. The initial range of alternatives was presented to the Village Administrator and Community Development Director in December 2017. Traffic signal timing was optimized for each Alternative to minimize total travel time and delay within the system and for specific arterial movements, and directly leads to reduced queuing and block intersections. Based on additional Village input, alternatives were added to study completely removing the potential for blocked intersections. In these cases (Alternative 2C, 2D, 3D, 3E, and 3F), traffic signal timings were optimized to clear blocked intersections with the result that the longer clearance intervals create a longer cycle length and additional delay. The preliminary preferred alternatives were presented to the Mount Prospect Plaza ownership (RAMCO) in March 2018. RAMCO indicated their preference for Alternative 2 with Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 11 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report a traffic signal at the SE Plaza to minimize impacts to the development and improve internal circulation. The year 2040 is the current regional planning horizon. Therefore, all alternatives were evaluated based on year 2040 traffic projections. The range of alternatives evaluated include- • Alternative 1- Add Auxiliary Lanes on Mount Prospect Road at Central Road and on Central Road at Rand Road • Alternative 2- Modify Plaza Main Exit to Southbound Right -Out Only • Alternative 213: Alternative 2 plus Add New Traffic Signal at SE Plaza Access Drive • Alternative 2C: Alternative 2B plus Add Dual Left Turn Lanes on Rand at Central in both directions • Alternative 2D: Alternative 2B with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 2E: Alternative 2C with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 3- Relocate Main Plaza Exit/Entrance • Alternative 313: Alternative 3 plus Add New Traffic Signal at SE Plaza Access Drive • Alternative 3C: Alternative 3B plus Add Dual Left Turn Lanes on Rand at Central in both directions • Alternative 3D: Closely Spaced Intersection Concept with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 3E: Alternative 3 with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 3F: Alternative 3C with upgraded traffic signal equipment to eliminate intersection blocking • Alternative 4- No Left Turns at Rand and Central Intersection • Alternative 5- Grade Separation at Rand and Central Intersection • Alternative 6- Modern Roundabout II. Baseline Condition The current regional planning horizon for all projects in the Chicago Metropolitan area desired to be eligible for federal funding is the year 2040. On this basis, 2040 traffic conditions are required to be evaluated as part of the Phase I Study. Two scenarios were evaluated in this regard; the 2040 No -Build scenario, which assumes no improvements to these intersections by the year 2040 other than normal required roadway maintenance. The year 2040 traffic Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 12 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report projections obtained from the Chicago Metropolitan Agency for Planning (CMAP) are included in Appendix 3. The 2040 No -Build scenario does not address the project purpose and need discussed above. Total delay and travel time increase compared to existing conditions due to projected increases in traffic by the year 2040. There will also be a Substantial increase to specific arterial movement travel time including Northwest (NW) Rand Rd and northbound (NB) Mount Prospect to Rand. The Village of Mount Prospect, in coordination with IDOT, will be resurfacing and restriping the Central/Mount Prospect intersection during the Summer of 2018 in conjunction with the IDOT Central Road resurfacing program. Specific elements include - Change southbound (SB) right turn lane (RTL) to combined Thru/RTL on Plaza Access at Rand. • Change SB RTL to Thru on Mount Prospect at Central. Advantages • Total delay, travel time, and queuing decrease compared to 2040 No -Build. • Decrease to many arterial movement travel times including northwest (NW) Rand Rd, northbound (NB) Mount Prospect and Rand, eastbound (EB) Central, and westbound (WB) Central. Disadvantages • Although it provides some level of cost effective improvement, it does not address the overall project purpose and need. Specific arterial movement travel times increase over 2040 No -Build to balance roadway approaches that are overcapacity, including southeast (SE) Rand, and SB Rand and Mount Prospect. Although this interim improvement decreases total delay and travel time for the network, the travel time reduction benefit is not seen for specific arterial movements including SE Rand, and SB Rand and Mount Prospect, due to signal optimization giving additional timing to WB and EB Central, NW Rand, and NB Mount Prospect and Rand. However, this interim improvement, analyzed with the 2040 traffic projections, is the baseline condition against which all Build Alternatives are compared. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 13 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report III. Build Alternatives Description and Analysis Results A description of each Build Alternative considered and a summary of the analysis results is provided below. A schematic of each Build Alternative considered is included in Appendix 1. The results of the completed evaluation, using the Synchro Traffic simulation computer analysis program is included in Appendix 2 with the comparative evaluation criteria shown in the first column. For ease of reference, queue exhibits showing resulting queue lengths directly follow each alternative in Appendix 1. Alternative 1: Add Auxiliary Lanes on Mount Prospect Road at Central Road and on Central Road at Rand Road With reference to the Alternative 1 exhibits in Appendix 1, Alternative 1 includes providing the following additional turn lanes - 0 Add SB RTL on Mount Prospect at Central. • Add NB RTL on Mount Prospect at Central. • Add EB RTL on Central at Rand. Advantages • Total delay, travel time, and queuing decrease compared to the Baseline Condition. • No new traffic signals. Disadvantages • SB Mount Prospect queue at Central Road intersection still backs into Rand. NB Mount Prospect and Rand PM travel time, and EB and WB Central AM travel time increases over Baseline Conditions due to additional timing benefit given to other movements. Summary Improves overall transportation network-, however, some other alternatives provide larger reduction in total delay and travel time. Alternative 1 is carried forward for further evaluation and stakeholder coordination. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 14 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report Alternative 2: Modify Plaza Main Exit to Southbound Right -Out Only In addition to Alternative 1, convert the SB Plaza exit at the Rand Road and Mount Prospect Road intersection to a RTL only to remove the split phase at the intersection and give more timing to other movements. Specific elements include - Alternative 1 improvements plus change SB Plaza to Right -Out only (remove thru/ left turn lane (LTL)). o Egress Plaza traffic was re -assigned to the new signalized intersection near the existing Walmart entrance. • Install new traffic signal northwest on Rand Road near the existing Walmart entrance. • Add WB dual LTL's on Walmart Entrance at Rand. Advantages • Total delay, travel time, queuing, and many arterial movement travel times decrease compared to Alternative 1. • Removes Alternative 1 disadvantage of travel time increases for NB Mount Prospect and Rand PM, and EB Central AM. Disadvantages • New traffic signal proposed, impacts internal circulation of Plaza. SB Mount Prospect queue still backs into Rand, but is confined to Rand RTL instead of through the intersection since the SW Plaza thru movement has been removed. WB Central AM peak hour travel time still increases over Baseline Condition due to additional timing benefit given to other movements. Summary Improves overall transportation network-, however, Alternative 3 provide larger reduction in total delay and travel time. The Mount Prospect Plaza ownership has indicated their preference to Alternative 2 with a traffic signal at the SE Plaza entrance (Alternative 2B). Alternative 2 is carried forward for further evaluation and stakeholder coordination. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 15 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report Alternative 2113: Alternative 2 plus Add New Traffic Signal at SE Plaza Access Drive In addition to Alternative 2, install new traffic signal at the existing SE Plaza access on Central Road located east of the Rand Road intersection. The location meets warrants for a proposed traffic signal. Advantages • Improves plaza accessibility by reducing queues within plaza. Disadvantages • Total delay, travel time, and mainline queuing increase slightly compared to Alternative 2. • WB Central Road travel time increases compared to Alternative 2. Summary Alternative 2B compensates for Plaza's loss of main egress at Mount Prospect Road by improving SE Plaza accessibility at the cost of Central Road user travel time. The Mount Prospect Plaza ownership has indicated their preference to Alternative 2B. Alternative 2B is carried forward for further evaluation and stakeholder coordination. Alternative 2C: Alternative 2B plus Add Dual Left Turn Lanes on Rand at Central in both directions In addition to Alternative 2, add dual left turn lanes on Rand Road at the Central Road intersection. Advantages • Decreases all arterial travel times compared to baseline conditions and decreases most arterials comparted to Alternative 2B. • Total delay, travel time, and mainline queuing decrease compared to Alternative 2 and 2B. Disadvantages • Requires proposed ROW in all four quadrants, and additional temporary easements needed for business access approximately 850 feet southeast of Central Road on Rand Road. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 16 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report • Design exceptions needed for the NW approach of Rand Road for LTL storage and taper lengths. Summary Widening and resurfacing Rand Road approximately 850 feet southeast and northwest through the Mount Prospect intersection to accommodate an additional left turn lane results in adjacent property impacts and traffic signal work at both Rand -Central and Rand -Mount Prospect intersections. Alternative 2C is carried forward for further evaluation and stakeholder coordination. Alternative 2113: Alternative 2B with upgraded traffic signal equipment to eliminate intersection blocking In addition to Alternative 213, retime intersections to remove potential for blocked intersections. The longer clearance intervals create longer cycle lengths (150 seconds), and additional delay and queueing outside the triangle intersection. Advantages • Removes blocked intersections within the closely spaced triangle intersections. Disadvantages • Total delay, travel time, and mainline queuing increases compared to Alternative 2B and is comparable to baseline conditions. Summary Alternative 2D addresses a key concern of blocked intersection at cost to total travel time and delay through the network. Alternative 2D is carried forward for further evaluation and stakeholder coordination if traffic signals are modified to one controller optimized to minimize blocked intersection. Alternative 2E: Alternative 2C with upgraded traffic signal equipment to eliminate intersection blocking In addition to Alternative 2C, retime intersections to remove potential for blocked intersections. The longer clearance intervals create longer cycle lengths (150 seconds), and additional delay and queueing outside the triangle intersection. Advantages • Removes blocked intersections within the closely spaced triangle intersections. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 17 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report • Providing dual lefts reduces queues at Rand Road and Central Road, and reduces total delay, travel time, and mainline queuing compared to the baseline condition. Disadvantages Requires proposed ROW in all four quadrants, and additional temporary easements needed for business access approximately 850 feet southeast of Central Road on Rand Road. • Design exceptions needed for the NW approach of Rand Road for LTL storage and taper lengths. Summary Alternative 2E addresses a key concern of blocked intersection and is the only "revised signal timing" alternative which reduces total travel time and delay through the network compared to the baseline condition. Alternative 2E is carried forward for further evaluation and stakeholder coordination if traffic signals are modified to one controller optimized to minimize blocked intersection. Alternative 3: Relocate Main Plaza Exit/Entrance In addition to Alternative 1, remove the existing Plaza Access at the Rand Road and Mount Prospect Road intersection and relocate it further northwest along Rand Road as a right -in, right -out only access point. Specific elements include - Alternative 1 plus relocate Plaza access further northwest on Rand, as a right -in, right - out only access point. o A concept modern roundabout (RAB) within the plaza is shown to improve overall circulation within the plaza. Further evaluation would be required to determine acceptability, parking impacts and reconfiguration requirements, and cost. • Install new traffic signal at the existing Walmart entrance. o SEB (thru/ left turning) Plaza traffic was re -assigned to the new signalized intersection near the existing Walmart entrance and NWB (right turning) Plaza traffic was re -assigned to the new plaza entrance. o SB Rand Road traffic entering the plaza was re -assigned to the Walmart entrance signalized intersection. NB Rand Road traffic entering the plaza was re -assigned to the new plaza entrance. • Add WB dual LTL's on Walmart Entrance at Rand. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 18 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report Advantages • Lowest total delay, travel time, and queuing of all alternatives analyzed for the PM peak hour. • Reduces arterial movement travel times compared to Alternative 2, and partially alleviates Alternative 2 disadvantage of WB Central AM travel time increases over Baseline Conditions. Disadvantages • New traffic signal proposed, impacts internal circulation of Plaza. • Added cost to reconfigure Plaza access. • Potentially added cost to reconfigure internal Plaza circulation if desired (i.e.; RAB and parking reconfiguration). • Requires ROW from Plaza and Century Supply Co. • SB Mount Prospect queue still backs into Rand RTL. Summary Improves overall transportation network, and provides the greatest reduction in total delay and travel time compared to Alternative 1 and 2. Alternative 3 is carried forward for further evaluation and stakeholder coordination. Alternative 3113: Alternative 3 Dlus Add New Traffic Sianal at SE Plaza Access Drive In addition to Alternative 3, add a proposed traffic signal at the SE Plaza access on Central Road, east of Rand Road. Specific elements include - Alt 3 improvements plus install new traffic signal at the existing SE Plaza access on Central Road located east of the Rand Road intersection. The location meets warrants for a proposed traffic signal. • Install new traffic signal aligned with Henry Street (in lieu of at the existing Walmart entrance). o A new concept RAB within the plaza is shown for reference to improve overall circulation within the plaza. Further evaluation would be required to determine acceptability, parking impacts and reconfiguration requirements, and cost. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 19 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report Advantages • Improves plaza accessibility by reducing queues within plaza. Disadvantages • Total delay, travel time, and mainline queuing increases compared to Alternative 3. • EB and WB Central Road travel time increases compared to Alternative 3. • Added cost to reconfigure Plaza access. • Potentially added cost to reconfigure internal Plaza circulation if desired (i.e.; RAB and parking reconfiguration). • Requires ROW from Plaza and Century Supply Co. Summary Alternative 3B compensates for Plaza's loss of main entrance at Mount Prospect Road by improving SE Plaza accessibility at the cost of Central Road user travel time. Alternative 3B is carried forward for further evaluation and stakeholder coordination. Alternative 3C: Alternative 3B plus Add Dual Left Turn Lanes on Rand at Central in both directions In addition to Alternative 313, add dual LTL's on Rand Road at Central Road and at the new WB Plaza exit across from Henry. Specific elements include - Alt 3B improvements plus add dual left turn lanes on Rand Road at Central Road intersection. • Dual left turn lanes at WB Henry St./ Mall Entrance. o A new concept RAB within the plaza is shown for reference to improve overall circulation within the plaza. Further evaluation would be required to determine acceptability, parking impacts and reconfiguration requirements, and cost. Advantages • Improves Rand -Central intersection and northwest -bound (NWB) and southeast - bound (SEB) LT movement LOS compared to Alternative 3. • Decreases SE Rand Rd and WB Central Rd travel time compared to Alternative 3. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 1 10 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report Disadvantages • Requires proposed ROW in all four quadrants, and additional temporary easements needed for business access approximately 850 feet southeast of Central Road on Rand Road. • Design exceptions needed for the NW approach of Rand Road for LTL storage and taper lengths. • Increases total delay and travel time compared to Alternative 3 due to additional traffic signal at SE Plaza. • Added cost to reconfigure Plaza access. • Potentially added cost to reconfigure internal Plaza circulation if desired (i.e.; RAB and parking reconfiguration). Summary Widening and resurfacing Rand Road approximately 850 feet southeast and northwest through the Mount Prospect intersection to accommodate an additional left turn lane results in adjacent property impacts and traffic signal work at both Rand -Central and Rand -Mount Prospect intersections. Alternative X is carried forward for further evaluation and stakeholder coordination. Alternative 3113: Closely Spaced Intersection Concept with upgraded traffic signal equipment to eliminate intersection blocking Relocate Mount Prospect Road east instead of relocating the Mount Prospect Plaza northwest to function like the Rand -IL 83 -Kensington Road closely spaced intersection. The longer clearance intervals create longer cycle lengths (150 seconds), and additional delay and queueing outside the triangle intersection. Advantages • Removes blocked intersections within the closely spaced triangle intersections. Disadvantages • Total delay, travel time, and mainline queuing increases compared to Alternative 3. • EB and WB Central Road travel time increases compared to Alternative 3. • Added cost to reconfigure Plaza access to right -in right -out only. • Requires ROW from Plaza and Century Supply Co. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 1 11 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report Summary Alternative 3D addresses a key concern of blocked intersection at cost to total travel time and delay through the network. Alternative 3D is not recommended as it does not meet the purpose and need to reduce total travel time and delay. Alternative 3E: Alternative 3 with upgraded traffic signal equipment to eliminate intersection blocking In addition to Alternative 3, retime intersections to remove potential for blocked intersections. The longer clearance intervals create longer cycle lengths (150 seconds), and additional delay and queueing outside the triangle intersection. To reduce created queue lengths, additional specific elements include- • Add NWB and SEB dual left turn lanes on Rand Road at Central Road. • Add exclusive NB left turn lane on Mount Prospect Road at Central Road. • Install new traffic signal at the existing Walmart entrance. Advantages • Removes blocked intersections within the closely spaced triangle intersections. Disadvantages • Total delay, travel time, and mainline queuing increases compared to Alternative 3. • Added cost to reconfigure Plaza access to right -in right -out only. • Potentially added cost to reconfigure internal Plaza circulation if desired (i.e.; RAB and parking reconfiguration). • Requires ROW from Plaza and Century Supply Co. Summary Alternative 3E addresses a key concern of blocked intersection at cost to total travel time and delay through the network. Alternative 3E is not recommended as it does not meet the purpose and need to reduce total travel time and delay. Alternative 3F: Alternative 3C with upgraded traffic signal equipment to eliminate intersection blocking Alternative 3E with a proposed traffic signal at the SE Plaza entrance. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 1 12 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report Advantages • Removes blocked intersections within the closely spaced triangle intersections. Disadvantages • Total delay, travel time, and mainline queuing increases compared to Alternative 3E. • EB and WB Central Road travel time increases compared to Alternative 3E. • Added cost to reconfigure Plaza access to right -in right -out only. • Potentially added cost to reconfigure internal Plaza circulation if desired (i.e.; RAB and parking reconfiguration). • Requires ROW from Plaza and Century Supply Co. Summary Alternative 3F addresses a key concern of blocked intersection at cost to total travel time and delay through the network. In addition, the alternative compensates for Plaza's loss of main entrance at Mount Prospect Road by improving SE Plaza accessibility at the cost of Central Road user travel time. Alternative 3F is not recommended as it does not meet the purpose and need to reduce total travel time and delay. Alternative 4: No Left Turns at Rand and Central Intersection In addition to relocating the existing plaza entrance as shown with Alternative 3, remove LTL's on Rand Road at Central Road to give more time to the thru movements. Extend the SE Plaza Access south across Central Road to Rand Road to accommodate left turning vehicles from WB Central to SEB Rand and from NWB Rand to WB Central. Specific elements include - In addition to Alternative 1, relocate Plaza access further northwest on Rand to align with Henry Rd. • Install new traffic signal at relocated Plaza access and at SE Plaza access point on Central. o Ingress and egress plaza traffic is re -assigned to the new signalized plaza entrance. o A new concept RAB within the plaza is shown for reference to improve overall circulation within the plaza. Further evaluation would be required to determine acceptability, parking impacts and reconfiguration requirements, and cost. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 1 13 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report • Add EB RTL on Henry Rd at Rand. • No left turns allowed at Rand -Central intersection. • Left turns occur prior to main intersection on short legs of Mount Prospect and SE Plaza, so LTL queues can't back into the other 2 intersections. • Add SB LTL on Mount Prospect at Central. • Add NB LTL on Mount Prospect at Central. • Relocate Burger King across from the SE Plaza Entrance. • Construct/Extend SE Plaza Entrance to Rand Road. Advantages • Additional time taken from LT's given to Central Road and Mount Prospect Road movements. Improves thru movements at the Rand -Central intersection. Disadvantages • Minimal benefits compared to baseline conditions. • Increased total delay and travel time compared to baseline conditions due to large NWB to WB LT movement at Rand -Central needing to go through 2 additional signals. • 3 new proposed traffic signals, impacts internal circulation of Plaza. • Added cost to reconfigure Plaza access. • Potentially added cost to reconfigure internal Plaza circulation if desired (i.e.; RAB and parking reconfiguration). • Requires ROW from Plaza, Century Supply Co., Burger King. • Business relocation (Burger King). • SB Mount Prospect queue backs into Rand RTL. Summary Alternative 4 is not recommended as it provides minimal benefit compared to 2040 No - Build with significant impacts and costs. Alternative 5: Grade Separation at Rand and Central Intersection Lower Rand Road and construct a Central Road overpass. Reconstruct the north section of Mount Prospect Road to lower the connection to Rand Road and extend the SE Plaza access Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 1 14 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report road to Rand Road. Provide a barrier median on Rand Road from Henry Street to the new SE Plaza access Roadway with the goal of improving travel times by removing 2 existing signals at Rand -Mount Prospect and at Rand -Central. Specific elements include- • New bridge carrying Central Road over Rand Road. • Relocate Plaza access further northwest on Rand to align with Henry Rd. • Install new traffic signal at relocated Plaza access. • Add EB LTL on Plaza Ent at Rand. • Add WB dual LTL's at Plaza Ent at Rand. • Add an additional RTL on Rand at Mount Prospect. • Change SB RTL to Thru on Mount Prospect at Central. • Add SB RTL on Mount Prospect at Central. • Add dual NB RTL's on Mount Prospect at Central. • Relocate Burger King across from the SE Plaza Entrance. • Construct/Extend SE Plaza Entrance to Rand Road. • Short legs of Mount Prospect and SE Plaza function as entrance/exit ramps. • Add EB RTL on Central at SE Plaza Entrance. • Add NB dual LTL's on SE Plaza Ent at Central. • Add SB dual RTL's on SE Plaza Ent at Rand. Advantages • Central Road and Rand Road thru movements' LOS and travel time improve. • Queuing at Rand and Central intersection eliminated. • Greatest improvement for the AM peak hour. Disadvantages • Less improvement for the PM peak hour due to high traffic volume for SEB Rand to SB Mount Prospect (movement carries all SB Mount Prospect, and EB and WB Central turning vehicles). • While removing 1 existing traffic signal, also adding 2 new proposed traffic signals, impacts internal circulation of Plaza. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 1 15 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report • Added cost to reconfigure Plaza access. • Potentially added cost to reconfigure internal Plaza circulation if desired (i.e.; RAB and parking reconfiguration). • Requires ROW from Plaza, Century Supply Co., Burger King. • Business relocation (Burger King). • Cost prohibitive (very high relative capital cost and future maintenance cost for bridge). • SB Mount Prospect queue backs into Rand RTL. Summary Total delay and travel time is lowest compared to the other alternatives for the AM peak hour travel period, however Alternative 5 provides similar benefits to Alternative 1 for the PM peak hour and is significantly more expensive. Alternative 5 is not recommended due to high cost with similar benefits to other alternatives. Alternative 6: Modern Roundabout with Rand Road Underpass A multi -lane modern roundabout (RAB) was considered at the Rand -Central intersection which would require at least a triple lane RAB. The impacts are shown on the Alternative 6 exhibit as a dashed 250 -foot diameter circle, which would require the relocation of 2 businesses. Based on the high circulating volume within the RAB (approximately 2,300 pc/h), operational complexity, impacts, and deficient performance, a RAB at the Rand -Central intersection was dismissed. Therefore, Alternative 6 assumes a Rand Road tunnel to bypass Rand Road thru traffic and a "dog -bone" double RAB over the underpass to accommodate Mount Prospect and Central Roadway users and Rand Road turning vehicles. Specific elements include- • New bridge carrying Central Road over Rand Road. • Relocate Plaza access further northwest on Rand and install a new traffic signal at this location. o A new concept RAB within the plaza is shown for reference to improve overall circulation within the plaza. Further evaluation would be required to determine acceptability, parking impacts and reconfiguration requirements, and cost. • Relocate Burger King across from the SE Plaza Entrance. • Construct/Extend SE Plaza Entrance to Rand Road. Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 1 16 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report • Install new traffic signal at SE Plaza for NWB Rand to WB or EB Central or SB Mount Prospect turning vehicles. • Install double "dog -bone" RAB at grade above Rand Road underpass. Advantages • Queuing at Rand and Central intersection eliminated. Disadvantages • Multi -lane RAB fails due to circulating traffic volumes (up to 2,300 pc/h). • 2 new proposed traffic signals (or RABs), impacts internal circulation of Plaza. • Property impacts with business relocation (Burger King, Mattress Firm). • Impacts access and internal circulation to all businesses adjacent to intersections. • Cost prohibitive (initial capital, future bridge maintenance) with IDOT cost participation unlikely. • IDOT District 1 does not have any constructed multilane RABs in their system and approval would be difficult. Summary Alternative 6 is not recommended due to high traffic volumes, operational complexity, impacts, deficient performance, and cost. Summary of Results In comparison to the baseline condition (2040 with Central/Mount Prospect Improvement), Alternatives 4, 5, and 6 would not provide overall traffic operations improvements, and had the highest estimated construction cost of all alternatives considered. On this basis, these alternatives were considered but are not recommended to be considered further because they provided limited benefit when compared to their high cost and impacts. Alternatives 1, 2, and 3 and their variations remain under consideration and are being further coordinated with project stakeholders. Alternative 3 would provide the lowest evening rush hour total delay and travel time compared to the baseline condition for all alternatives with relatively low impacts and cost. Alternatives 1 and 2 also provide improvements over the baseline condition with relatively low impacts and cost. Alternatives 1, 2, and 3 were discussed with the Mount Prospect Plaza managing company (i.e.; RAMCO) on March 14, 2018, and the meeting summary is included in Appendix 4. RAMCO expressed support for Alternative 2 as it includes the channelization improvements proposed by Alternative 3, but Rand -Central -Mount Prospect Road Intersections I Alternatives Evaluation Report Page 1 17 Rand -Central -Mount Prospect Road Intersections Alternatives Evaluation Report converts the Plaza exit to a right -out only which still gives additional signal time to other traffic movements, but to a lesser extent than Alternative 3. RAMCO indicated that Alternative 3, which relocates the Plaza entrance/exit presents many challenges as the access is stipulated via separate leases for each store within the Plaza. If Alternative 3 is chosen, a condemnation process may be necessary based on all the required agreements between parties. RAMCO also requested a traffic signal at the southeast Plaza entrance to improve internal Plaza circulation and balance the loss of the through/ left turn lane at the Mount Prospect Road exit, which is Alternative 2B. Alternatives 3D, 3E, and 3F were developed to further investigate a key concern of completely removing blocked intersections at the Rand -Central -Mount Prospect intersection triangle. Alternatives 3D, 3E, and 3F are not recommended as optimizing the traffic signal timing to clear blocked intersections results in longer clearance intervals which create a longer cycle length and additional delay. Similarly, Alternative 2C and 2D were developed to investigate revising timings to remove blocked intersections from Alternative 2B and 2C, respectively. These performed much better than the Alternative 3 variations previously described in that the Alternative 2D total delay and travel time is similar to baseline conditions and Alternative 2E reduces total delay and travel time over baseline conditions with the added benefit of removing the potential for blocked intersections at the triangle with the longer clearance intervals. Next Steps Further coordination of Alternatives 1, 2, 2B, 2C, 2D, 3, 3B, and 3C in consideration of the input received from the Mount Prospect Plaza management company, is planned with Walmart, the Cook County Division of Transportation and Highways (CCDOTH), the City of Des Plaines, IDOT, and FHWA. Based on this coordination, the finalist alternative(s) will be identified, further developed to a concept plan stage, and will be presented at a second Public Information Meeting for all project stakeholders (motorists, residents, businesses) to have an opportunity to review and comment on the overall alternatives evaluation process and results, and to offer comments on the preliminary concept design for the finalist alternative(s) presented. Public Information Meeting #2 is anticipated in mid -Summer. Subsequent to the Public Information Meeting #2, the preferred alternative will be identified, with detailed engineering plans and studies developed and coordinated with IDOT and FHWA for review and approval of the Phase I Study. Completion of the Phase I Study is anticipated by the end of 2018 or early 2019.

August 10, 2017 Rand -Central -Mount Prospect Road Public Information Meeting #1 11 MEETING SUMMARY Meeting Date: March 14, 2018 at 10:00 a.m. Location: Mount Prospect Village Hall Project: Rand -Central -Mount Prospect Phase I Engineering Study SN. 17 -00166 -00 -CH Purpose: Mount Prospect Plaza Coordination Meeting Attendees: See attached sign -in sheet A coordination meeting was held at the Village of Mount Prospect on March 14, 2018 at 10 a.m. for the Rand -Central -Mount Prospect Phase I Engineering Study to discuss the Phase I study and preliminary results with the Mount Prospect Plaza ownership (i.e.; RAMCO Gershenson Properties Trust). Meeting material distributed included discussion points and the Range of Alternative Concept Evaluation White Paper. Sketches of the alternatives were displayed for discussion purposes. The SimTraffic computer traffic modeling of the alternatives was used to facilitate discussions. Below is a summary of meeting discussion points, with any action items noted: 1) The Phase I Engineering Study is intended to address the need for transportation related improvements to the closely spaced intersections involving Rand Road, Central Road, and Mount Prospect Road, with the goal to improve congestion, mobility, access, safety, and non -motorized accommodations. 2) A public information meeting was held on August 10, 2017 to explain the project objective and gain public input on existing transportation issues. The existing conditions SimTraffic was shown at the coordination meeting which reflects stakeholder input that exiting the Plaza at Mount Prospect Road and Rand Road is difficult. Queues also develop at the SE Plaza entrance located near Lifetime Fitness. The 2040 No -Build was shown which shows the existing traffic problems getting worse due to the increase of projected traffic volumes. RAMCO asked if the projected traffic volumes reflected anticipated changes in autonomous vehicles. CBBEL explained that the Chicago Metropolitan Agency for Planning (CMAP) is the 3rd party agency responsible for providing traffic volume projections for northeastern Illinois, and they are considering potential future mode shifts with their travel demand projections. In discussion with CMAP, it is uncertain what effects autonomous vehicles may have on traffic volumes in the future, but agencies such as CMAP and the Federal Highway Administration (FHWA) are evaluating this issue. Currently, there are many divergent opinions on whether traffic volumes will increase or decrease as a result. 3) An interim permit project is anticipated later this year to resurface and restripe Mount Prospect Road at Central Road. Currently, the southbound (SB) movement on the north leg of Mount Prospect Road at Central Road is an exclusive right turn lane (RTL) and a combined thru/left turn lane (LTL). The exclusive RTL will be restriped to a combined thru/RTL and the south receiving end of Mount Prospect Road will be restriped as two lanes with the lane drop further south. No work is proposed at the Mount Prospect Road/ Plaza and Rand Road intersection as part of this project as it would increase IDOT involvement in the approval process. The Plaza SB exit similarly has an exclusive RTL and combined thru/LTL. Vehicles exiting the Plaza are queuing in the RTL to go straight. With this interim permit project, the Plaza may now restripe the RTL to a combined thru/RTL for these vehicular movements. The Village will coordinate with the Plaza as the resurfacing and restriping project progresses as this provides a good benefit to the Plaza egress. The Central Road resurfacing project is expected to start in June. RAMCO agreed that this would be a good interim solution and would like all three representatives included in future coordination with Bridget Goggin as the main contact. 4) For the Phase I Engineering Study, a full range of alternatives were comparatively evaluated and results were summarized in the white paper previously provided by the Village. Alternatives 1, 2, and 3 show incremental better network improvements with Alternative 3 having the best overall network improvement. Alternative 3 was identified as the overall most cost-effective of these alternatives. RAMCO indicated that relocating the Plaza entrance/exit presents many challenges as the access is stipulated via separate leases for each store within the Plaza. If Alternative 3 is chosen, a condemnation process may be necessary based on all the required agreements between parties. Alternative 2 as shown does not have a traffic signal at the SE Plaza entrance. RAMCO prefers Alternative 2 modified with a traffic signal at the SE Plaza entrance as this would minimize site impacts, however further research is necessary to determine what agreements would be necessary with each leaser to convert the access to a right -out only. A proposed traffic signal meets warrants at the SE Plaza. 5) Sub -alternatives were further studied for Alternative 3 to build upon the best -performing alternative. Alternative 3B investigated how adding a traffic signal at the SE Plaza would affect the network performance. The queues within the plaza are better managed, however the network delay and travel time increases due to the introduction of a new traffic signal. While the proposed traffic signal relocated along Rand Road is shown in various locations for the alternatives with a range of impacts to the Walmart parking field, based on recent development plans with the vacant parcel across from Walmart, it is likely that the proposed traffic signal will be located at the existing Walmart access at the loading docks opposing a new proposed development. 6) RAMCO asked whether roundabouts were feasible at the interconnected triangle intersections. Multi -lane roundabout (RAB) had been considered at all three intersections. The Rand -Central intersection which would require at least a triple lane RAB, and the high circulating volume within the RAB (approximately 2,300 pc/h) resulted in operational complexity, property impacts, and deficient performance, therefore a RAB at the Rand -Central intersection was dismissed. In addition, a "dog - bone" double RAB covering both Mount Prospect at Central Road and Mount Prospect at Rand Road was considered. Similarly, the multi -lane RAB has a large footprint resulting in significant property and access impacts to adjacent businesses, and deficient traffic performance. Rand Road and Central Road west of Rand Road are under IDOT jurisdiction. IDOT District 1 does not have any constructed multi -lane RABs in their system due to the issues described above and high truck volumes on state routes. 7) CBBEL described the next steps for the Phase I Engineering Study process. Coordination with Walmart is pending to gain their feedback on the alternatives discussed today. RAMCO plans to contact the Walmart management to discuss the project and help set up that meeting. Once a preferred alternative is determined, a public hearing is anticipated in the fall to present the preferred alternative, and Design Approval from IDOT and FHWA is anticipated by the end of 2018. After Phase 1, Phase 11 is the detailed design phase with contract plan preparation and land acquisitions and usually takes 18-24 months.
