A)
REQUEST FOR TRAFFIC CONTROL SIGNS AT THE INTERSECTION OF ALBERT
STREET & LINCOLN STREET
I) Background Information
Residents petitioned the Village to consider installing Stop or Yield signs at the intersection of
Albert Street and Lincoln Street. Ms. Susan Eyles, 320 S. Albert Street, lives near this
uncontrolled intersection and believes it is unsafe. She called the Village after a recent accident
at the intersection and is concerned for the safety of motorists and pedestrians in the area.
This item was originally discussed at the November 10, 2003 Safety Commission Meeting. At
the meeting, the Commission voted to hold off on making a decision until Staff had an
opportunity to work with the homeo~vner at 1000 E. Lincoln Street about trimming a private
property evergreen tree. This tree had branches that overhung the sidewalk and were lower than
8' above the ground. The amount of trimming that could be accomplished would affect the sight
distance for motorists and influence whether Staff would recommend Stop or Yield signs.
2) Staff Study
A letter was sent to the homeo~vner at t000 E. Lincoln Street on November 11, 2003 requiring
trimming of any branches that overhung the public right-of-way to a point 8' above the ground.
The homeowner contracted a private company to trim the tree such that the lowest branches are
now 8' above the ground. The sight distance for motorists approaching the intersection has
increased and improved safety because of the trimming.
As discussed at the November Safety Commission Meeting, 4-way Stop signs are not warranted
for the intersection.
2-way Stop signs are normally warranted at intersections where the criteria for a 4-way Stop sign
installation is not met but where a full stop is necessary at all times on one street in order to
clarify the right-of-way. When considering 2-way Stop or Yield signs, typical engineering
practice is to determine the safe approach speed for the direction to be controlled. If a motorist
must slow down to lower than 15mph when approaching an intersection because of a sight
obstruction, Stop signs should be used rather than Yield signs. Else, Yield signs should be used.
For this case, a majority of the evergreen tree falls within the area that is to be free of any sight
obstructions for a westbound motorist traveling at 15mph. Before the trimming, the tree was
considered a sight obstruction because of its low hanging branches. The recent trimming of the
tree, however, has increased the sight distance so that the safe approach speed is greater than
15mph and a full stop is not necessary at all times. Motorists can react and stop to give the right-
of-way if necessary using less restrictive measures such as Yield signs. Therefore, 2-~vay Stop
signs are not warranted.
At intersections where a full stop is not necessary at all times, consideration should be given to
using less restrictive measures such as Yield signs. Yield signs assign right-of-way to traffic
when the normal right-of-way rule appears to not be effective. 3 accidents in the past 3 years
reveal this may be the case. Also, the speed data shows that because of the proximity of the
homes and landscaping to the intersection, motorists may not have enough time to see other
3)
4)
vehicles on the cross street, react and stop before reaching the intersection given the current
uncontrolled situation. Motorists controlled by Yield signs would need to slow doxvn before
reaching the intersection resulting in a shorter distance to come to a full stop if necessary.
Finally, when installed, Yield signs should be placed on the minor street. Since the traffic
volume is similar on both streets, Staff reviewed the traffic control signs on adjacent
intersections and the recorded speeds on both streets to determine the appropriate street to be
given the right-of-way.
Recommendations
Based on the traffic study performed by Staff, the Village Traffic Engineer recommends:
approval of Yield signs on Lincoln Street at Albert Street.
Discussion
Chairman Bencic opened up the discussion to the audience. Mr. Hans Lim, 324 S. Albert Street,
expressed a desire to see Stop signs installed at the intersection.
Chairman Bencic asked if there were any questions from the Commission. There were none.
Chairman Bencic asked Traffic Engineer Lawrie to provide an overview of Staff's report to the
Commission. Traffic Engineer Lawrie shared Staff's efforts in working with the homeowner at
1000 E. Lincoln Street to have a private property evergreen tree trimmed to improve the sight
lines at the intersection. He also stated Staff's recommendation to install Yield signs.
Chairman Bencic asked how high the homeowner trimmed the evergreen tree. Traffic Engineer
Lawrie said 8'.
Commissioner Bjork, seconded by Commissioner Keane, moved to approve the
recommendations of the Village Traffic Engineer and approve Yield signs on Lincoln
Street at Albert Street.
The motion was approved by a vote of 9-0.
NEW BUSINESS
A) WE-GO TRAIL IMPROVEMENTS
1) Background Information
The Village has included We-Go Trail between Lincoln Street and Shabonee Trail as part of the
2004 Resurfacing Program. The street is showing signs of deterioration and is in need of repair.
It currently has a 17' wide asphalt pavement with curb on the east side and a 4' wide stone
shoulder on the west side. Parking is allowed on both sides of the street. There are 16 homes on
the east side of the street and 5 homes on the west side. The Mount Prospect Golf Course also
borders the west side of the street.
2)
This issue was presented to the Safety Commission in order to discuss traffic-related issues
brought to the Village's attention by concerned residents as a result of plans to resurface We-Go
Trail between Lincoln Street and Shabonee Trail in 2004.
Staff Study
Standard Village policy is to install curb on both sides of the street when one side already has
curb. Adding curb reduces long-term costs associated with maintaining a stone shoulder,
provides a buffer between vehicles and people, and improves roadway drainage. In the past,
numerous streets including portions of Council Trail, Forest Avenue, Helena Avenue, Laxvrence
Lane, Lincoln Street, Marcella Road, Meier Road, Moehling Drive and Prospect Avenue were
similar to We-Go Trail and curb was installed on the missing side of the street when it came time
to resurface. Also, a portion of Lonnquist Boulevard will get curb on both sides in 2004 where it
currently exists on one side.
In addition to adding curb to the west side of the street, the Village also has considered widening
the street. The 17' wide pavement along We-Go Trail is one of the narrowest, if not the
narrowest, public streets in the Village. The stone shoulder actually serves as part of the
roadway since it is difficult to maintain two-way traffic in its current state. The only recorded
accident along this stretch of We-Go Trail over the past five years involved a northbound vehicle
and southbound vehicle clipping each other as they passed. Village Code dictates new public
streets to have 28' wide pavement with curb and gutter on both sides (31' back-of-curb to back-
of-curb) with sidewalk. Knowing that the residents would prefer to maintain the "rural feel" of
the neighborhood, Staff was willing to modify our standard.
In November, the Village sent a survey to the residents and golf course requesting their opinion
on four proposed options for the cross-section and parking restrictions of the road. None of the
options included new sidewalk on the west side of the street. Two options involved 24' wide
pavement (27' back-of-curb to back-of-curb). This would be similar to the other streets in the
neighborhood. Of these options, one allowed parking on both sides and one allowed parking on
the east side only. The other two options involved 19' wide pavement (22' back-of-curb to back-
of-curb). This would be similar to the existing road width including the stone shoulder. Of these
options, one allowed parking on the east side only and one prohibited parking on both sides.
Of the 22 surveys, 14 (64%) were returned to the Village. A majority of them favored Option C.
This option would provide a 19' wide pavement (22'back~of-curb to back-of-curb) and allow
parking on the east side of the street only. Of the 12 properties who voted for Option C, 6
indicated their first preference is to replace the road in its present condition (17' wide pavement
with 4' stone shoulder on the west side) even though it wasn't presented as an option.
After the Village sent out the surveys to the residents, the Village received a letter from a
resident who organized a neighborhood meeting. The letter includes numerous questions and
suggestions related not only to the proposed road work but traffic safety issues. According to the
residents, the two primary concerns are the amount of through traffic to the golf course and
speeding. In summary, Staff does not support a one-way street, speed humps, additional Stop
signs or a 15mph speed limit as suggested by the residents. A two-day traffic study performed
along We-Go Trail in 2000 showed the daily volume to be under 500 vehicles. By making the
street one-way, surrounding streets such as See-Gwun Avenue, which already experiences four
times the amount of vehicles compared to We-Go Trail, would experience additional traffic. The
traffic study also showed average speeds from 22-25mph on We-Go Trail. As is typical on most
3)
residential streets, a small percentage of drivers did exceed the speed limit. Speed limit signs are
not posted along this portion of We-Go Trail, therefore, it is 30mph per the Village Code. Most
of the streets in the neighborhood have either no speed limit signs or a posted 25mph speed limit.
In our recent letter to the residents, Staff did offer to gather speed and volume data next summer
and provide the results to the Police Department for speed limit enforcement. Also, Staff has
given consideration to posting a lower speed limit of 25mph along We-Go Trail based on the
2000 traffic study and to be consistent with surrounding streets.
Recommendations
Staff's preference is a 24' wide pavement cross-section with curb and gutter on both sides of the
street and parking restricted to the east side only. This cross-section is narrower than what
Village Code dictates but is consistent with the streets in the neighborhood. Also, this cross-
section allows two-way traffic to be maintained even with parking on one side of the street.
However, Staff would not object to building a 19' wide pavement cross-section with curb and
gutter on both sides of the street as voted by a majority of residents. Parking would have to be
prohibited on at least one side of the street if not both. Since on-street parking is sometimes
observed, allowing parking on the east side only would be acceptable.
The 19' wide pavement cross-section with curb and gutter on both sides of the street would be
substantially different from the Village's standard for streets with curb and gutter. However, a
few unique factors have caused Staff to consider this option. First, the pavement width would
almost be identical to the current width thus retaining the narrow look of the street. From an
aesthetic standpoint, many residents would prefer to maintain a rural look. Second, a narrower
19' wide pavement would save in construction costs when compared to the 24' wide pavement.
Also, mature trees near the intersection of Shabonee Trail may be saved and continue to provide
a buffer from the golf course with a 19' wide pavement. Also, a narrow street with parking only
on one side should not be an inconvenience to the residents. A standard pavement ~vidth is built
to typically allow parking on both sides of the street. With only a few homes on the west side of
the street, on-street parking for the residents is not in high demand. Finally, there is little
opportunity for further development along this portion of We-Go Trail. Village Code would
require a new development to improve a street to meet typical standards.
Staff does not support leaving the street with its current cross-section. The combination of the
narrow street and lack of curb does not discourage motorists from driving on the stone shoulder
and grass. Not only does this result in an increase in maintenance costs but also does not provide
a buffer between vehicles and people who may be on the parkway.
Whether it is approved to build a 24' wide pavement or 19' wide pavement, parking should be
limited to at least one side of the street only. As it is now, vehicles parked on the west side do so
on the grass. By adding curb, parking would be confined to the roadway. With a 24' wide
pavement, two-way traffic could be maintained with parking restricted to one side of the street.
With parking restricted to one side given a 19' wide pavement, vehicles approaching from
opposite directions could not simultaneously pass each other and a parked car. However, having
on-street parking for the residents is important and may also influence vehicle speed. Since a
majority of the homes are on the east side of the street, Staff decided it would be appropriate to
allow parking on this side. A majority of the residents voted to allow parking on the east side
only.
4)
The residents have expressed a concern with cut through traffic and speeding. In their letter,
they provided suggestions to address these concerns. The request to make the street one-way
may reduce golf traffic on We-Go Trail but will add traffic to surrounding streets such as See-
Gwun Avenue. The residents along See-Gwun Avenue already take issue with the amount of
traffic on the street. Adding any more traffic ~vill certainly exacerbate this situation. Staff,
therefore, does not support this request. The other requests (Stop signs, speed humps, lower
speed limit to 15mph) are measures the residents believe will reduce vehicle speed. However,
according to the speed data collected in 2000, average speeds are already below the speed limit
and there have been no accidents associated with speeding. Also, Staff does not believe these are
effective measures to address a perceived speeding problem.
To address the concerns of the residents, a narrow street such as a 19' wide pavement may keep
average speeds and volume similar to what they are today and not further exacerbate the
perceived problem. Also, based on the speed data collected in 2000 and to be consistent with
surrounding streets, Staff believes a 25mph speed limit along We-Go Trail would be more
appropriate than the current unposted 30mph speed limit. Finally, Staff would be willing to
gather speed data next summer and provide this information to the Police Department for
enforcement purposes. Staff believes the combination of these measures would be more
effective in addressing the concerns of the residents.
Based on Engineering Staff analysis and the input from residents, the Village Traffic Engineer:
prefers a 24' pavement cross-section with curb and gutter on both sides of the street along
We-Go Trail between Lincoln Street and Shabonee Trail
but will not object to a 19' pavement cross-section with curb and gutter on both sides of the
street along We-Go Trail between Lincoln Street and Shabonee Trail
and further recommends to:
· prohibit parking along the west side of We-Go Trail between Lincoln Street and
Shabonee Trail
· lower the speed limit from 30mph to 25mph along We-Go Trail between Lincoln Street
and Shabonee Trail
· perform a speed study along We-Go Trail in 2004 after completion of road work and
golf course work
Discussion
Chairman Bencic opened up the discussion to the audience. Mr. Ron Nobles, 420 S. We-Go
Trail, serves as the spokesperson for the street. The rural look is very important to the residents
and he would not like to see the street widened. He believes the current width of the street does
not pose a problem for traffic. Also, he is concerned that any widening will only exacerbate the
current speeding issue seen by the residents. If a curb is to be installed on the west side of the
street, he would prefer that no portion of the grass be taken to do so.
Mr. John Hupp, 500 S. We-Go Trail, would prefer the street to remain with its current width. He
sees the widening as an intrusion onto the la~vns of those who live on the west side of the street.
If one of the options as presented is to be chosen, he would prefer Option C.
6
Mr. Jim McGehee, 507 S. We-Go Trail, expressed a concern ~vith tree removal that would be
necessary near Shabonee Trail and additional water that would be added to the sewer system. He
also questioned the advantages of adding curb versus leaving the stone shoulder. Traffic
Engineer Lawrie responded that in addition to savings in maintenance costs, the curb would
provide a buffer between vehicles and people on the parkway and improve drainage in the
roadway. Also, the Village over the years has had a policy of installing curb on both sides when
it comes time to resurface a street that only has curb on one side.
Mr. John Heidcamp, 400 S. We-Go Trail, expressed a concern with the expense of installing
curb. He would like to see the stone shoulder remain. Mr. Bures responded that Public Works
crews visit We-Go Trail and other non-curbed streets on average a couple of times a year. The
cost not only includes the stone but the labor, equipment and time preparing for the work as well.
With curbed streets, crews do not have to dedicate time to maintenance and are able to perform
other tasks in the Village.
Mr. Nobles asked for reasoning as to why the street should be widened. Village Engineer
Wulbecker, who was in attendance, said that the Engineering Staff had a different perspective.
The Village Code dictates a public street, when developed, is to be 31' back-of-curb to back-of-
curb. Staff had to determine what would cause them to recommend a narrower street. The four
options presented to the residents were acceptable options to Staff.
Ms. Joy McGehee, 507 S. We-Go Trail, said that consideration should be given to the design of
the intersection of Shabonee Trail and We-Go Trail to control speeding. She also expressed a
concern with the impact of the additional water to the sewer system and the character of the
neighborhood with widening the street.
Mr. Don Olsen, 403 S. We-Go Trail, questioned the need to install curb and widen the street.
Village Engineer Wulbecker spoke about similar streets in the neighborhood and the precedent of
~nstalling curb on streets. He also mentioned as We-Go Trail was scheduled for resurfacing in
2004 it ~vas reasonable for Staff to look at improving the street.
Ms. Donna Heidcamp, 400 S. We-Go Trail, believes it would be unsafe to widen the street
because vehicles already speed when turning from Lincoln Street. She is concerned for the
safety of the people along the street. Also, she does not want to lose the historic feel of the
neighborhood.
Ms. Kathy Wagner, 501 S. We-Go Trail, would like to see Stop signs installed at Go-Wando
Trail to control speeding along the street. She is unsure how the new clubhouse will impact
traffic along We-Go Trail.
With no more comments from the audience, Chairman Bencic brought the issue back to the
Commission.
Commissioner Bjork supported installing curb believing children would be cautious near the
street. She also said that residents learn to cope with traffic wherever they live in the Village.
She sees the importance of improving Village streets and suggested the trees near Shabonee Trail
could possibly be transplanted.
A couple of residents commented on wanting to save the trees along the street and keep the
uniqueness of the street intact.
Commissioner Tortorello pointed out that the residents should have been aware of the right-of-
way when they purchased their houses. She believes that the street should be brought up to
current standards and match other streets in the neighborhood because it is safer for vehicles
traveling along the street rather than a narrow street.
Mr. Bures said that he believes adding curb xvill make the street safer. Also, curb typically will
last for 50 years or more, therefore, reducing costs associated with maintaining a stone shoulder.
He believes that constructing a wider street ~vill provide more room between vehicles and
pedestrians that may be in the street. A wider street also would allow emergency vehicles easier
access to a house if necessary. Finally, he mentioned that the stone pillars near Shabonee Trail
are an obstruction and should be removed. Adding a curb will help to keep vehicles on the
roadway similar to what the stone pillars do now.
A couple of residents commented that the neighborhood has not changed which should not
prompt a change to the street.
Commissioner Grouwinkel supports installing curb but sees the narrow street as outlined in
Option C as a compromise given the historic look of the neighborhood.
Commissioner Keane expressed a concern with hindering emergency vehicle access with a
narrow street. One resident indicated there has never been a problem in the past with emergency
access.
Chairman Bencic asked Traffic Engineer Lawrie to provide a review of report to the Commission
and audience. Traffic Engineer Laxvrie went over the report explaining Staff's support of
installing curb on both sides of the street and having no objection to not installing sidewalk on
the west side of the street. With respect to the road width and parking restrictions, he mentioned
factors such as the width of surrounding streets, need for on-street parking, usage of the street
and potential for new development that ultimately resulted in four options. Each of these options
is acceptable to Staff and surveys were sent to the residents to solicit their opinions. Traffic
Engineer Lawrie told the Commission the results of the survey. He also briefly described each of
the options to the audience and Commission.
Traffic Engineer Lawrie touched on the issue of speeding as raised by some of the residents. He
explained the appropriate use of Stop signs and why Staff doesn't support speed bumps. He
recommended lowering the speed limit to 25mph and was willing to gather additional speed data
next year to assist the Police Department in enforcement.
Traffic Engineer Lawrie also touched on the issue of drainage and explained the Sewer system in
the neighborhood. Staff does not believe any widening of the street will have a significant
impact to the system. Na-Wa-Ta Avenue has a similar system to We-Go Trail and has
development on both sides of the street and a wider street. Also, he mentioned the golf course
redevelopment xvill contain their storm water on-site and will not be connected to the sewer
system that services We-Go Trail.
Commissioner Keane asked how many trees would need to be removed given the different
options. Traffic Engineer Lawrie said a Village Forestry representative inspected the street and
believed 5-6 trees would need to be removed with Options A and B. All of these trees are near
Shabonee Trail. With Options C and D, 34 trees would need to be removed. Traffic Engineer
8
Lawrie said the Village could look at xvays to recreate a buffer between the street and golf course
with trees that had to be removed.
Commissioner Arndt questioned how the current width of the street compares to each of the
options. Traffic Engineer Lawrie explained there is currently a 17' wide asphalt pavement with
4' stone shoulder. Options A and B call for a 24' pavement and Options C and D call for a 19'
pavement.
Chairman Bencic brought the issue back to the Commission. He summarized five issues that the
Commission needed to decide: the width of the asphalt pavement, whether or not install curb and
gutter on the west side of the street, whether or not to install sidewalk on the west side of the
street, parking restrictions, and the speed limit.
Commissioner Keane made a motion to:
· provide a 24' wide asphalt pavement along We-Go Trail between Lincoln Street and
Shabonee Trail
· install curb and gutter on the west side of the street
· not install sidewalk on the west side of the street
· allow parking on both sides of the street
· lower the speed limit from 30mph to 25mph
Commissioner Keane was asked to clarify the motion regarding the parking restrictions. He
believed that there hasn't been a problem with on-street parking and didn't see the need for
restrictions. In addition, adding signs would detract from the took of the street.
Chairman Bencic reiterated the motion.
Commissioner Bjork seconded the motion.
There was no further discussion.
The motion was approved by a vote of 6-3.
Chairman Bencic stated that he opposed the motion because he favored parking restrictions on
the west side of the street. He did support the 24' wide pavement.
Chairman Bencic told the audience that the Safety Commission was a recommending body and
this issue would go before the Village Board for a final decision. Traffic Engineer Lawrie said
this issue could be heard at the Village Board on Tuesday, December 16th but he wanted to be
sensitive to the residents' schedules should there be conflicts being close to the holidays. The
consensus from the audience was to defer the issue until the first meeting in January.
Commissioner Grouwinkel said that he opposed the motion because he believed the 19' wide
pavement with curb on both sides of the street was the safest solution.
Commissioner Arndt said that she shared the same feelings as Commissioner Grouwinkel and
believed emergency vehicles would not be hindered with a narrow street.
Traffic Engineer Lawrie said Staff would be willing to provide notice to the residents in a few
weeks reminding them of the Village Board meeting.

REQUEST FOR TRAFFIC CONTROL SIGNS AT THE INTERSECTION OF HI-LUSI
AVENUE AND MIl, BURN AVENUE
Background Information
Residents petitioned the Village to consider installing Stop or Yield signs at the intersection of
Hi-Lusi Avenue and Milbum Avenue. Mr. Jason Fried, 220 S. Hi-Lusi Avenue, lives near this
uncontrolled intersection and is concerned for the safety of motorists and pedestrians in the area.
The surrounding intersections have either Stop or Yield signs and many motorists disregard the
normal right-of-way rule.
Staff Study
The Engineering Staff performed a traffic study. The findings are as follows:
a) Accidents
A search of the accident reports indicated:
Year 1998 1999 2000 2001 2002 2003
(Nov)
Number of
Accidents 0 0 0 0 1 0
b)
c)
Speed Study
Representative speed surveys were performed at all four legs of the intersection between
November 11th and 18th. The average and 85th percentile speeds are as follows:
Northbound Hi-Lusi Avenue
Southbound Hi-Lusi Avenue
Eastbound Milburn Avenue
Westbound Milbum Avenue
Average 85th %
22 mph 28 mph
23 mph 28 mph
23 mph 28 mph
21 mph 25 mph
The speed limit on Hi-Lusi Avenue is 20mph. The speed limit on Milburn Avenue is
25mph. As is evident on most residential streets, the data shows some motorists did
drive above the speed limit. Under 4% of vehicles were traveling over 30mph and under
I% were traveling over 40mph.
Traffic Volume
Traffic volume data was gathered in November. Based on the results, there are
approximately 660 vehicles per day that enter the intersection. 310 vehicles travel on Hi-
Lusi Avenue and 350 vehicles on Milburn Avenue. The peak hour of the day (typically
8am-9am) experiences approximately 70 vehicles that enter the intersection.
10
3)
d) Survey Results
A total of 19 surveys were sent out in November 2003 to collect the residents' comments
on this request. 8 surveys (42%) were returned to the Village. Many of the responses
indicated motorists often speed through the intersection and support either Stop or Yield
signs. One response opposed Stop signs.
e) Existing Traffic Control Signs
Traffic control signs adjacent to the intersection are as follows:
Hi-Lusi Ave. & Evergreen Ave. (north) - 2-way Stop signs on Hi-Lusi Ave.
Hi-Lusi Ave. & Lincoln St. (south) - 2-way Stop signs on Hi-Lusi Ave.
Milbum Ave. & I-Oka Ave. (east) - 4-way Stop signs
Milbum Ave. & Wa-Pella Ave. (west) - 4-way Stop signs.
f) Sight Obstructions
Based on an inspection of the area, there is not any landscaping at any of the comers
causing a severe sight obstruction. Since this is an uncontrolled intersection, there is to
be sufficient stopping sight distance for all four legs of the intersection. Stopping sight
distance is the distance a vehicle travels from the point when a motorist sees an
approaching vehicle on the cross street, reacts and comes to a full stop. A motorist
should have enough clear vision to be able to stop, if necessary, before reaching the
intersection.
Landscaping near the homes and even the homes themselves at the intersection do not
provide sufficient stopping sight distance for motorists. Therefore, Stop or Yield signs
would assist in clarifying the right-of-way and possibly reduce the potential for an
accident.
Recommendations
4-Way Stop Signs
4-way Stop signs are normally warranted at intersections where there is a condition of severely
restricted view, accidents or a significant amount of vehicles and pedestrians. Based on an
inspection, there are no sight obstructions immediately at the intersection that would cause a full
stop to be necessary for all four directions. In addition, there has been 1 accident over the past 5
years. In order to meet the criterion for a multiway stop sign installation, there is to be 5
accidents in a 12-month period. Finally, the peak hour of the day experiences approximately 70
vehicles entering the intersection. In order to meet the criterion, the volume entering the
intersection from the major street approaches (total of both approaches) is to average 300
vehicles per hour for any 8 hours of the day and 200 vehicles per hour for the same 8 hours from
the minor street approaches. Based on the data, 4-way Stop signs are not ~varranted at this
intersection.
2-Way Stop Signs
2-way Stop s~gns are normally warranted at intersections where the criteria for a 4-way Stop sign
installation is not met but where a full stop is necessary at all times on one street in order to
clarify the right-of-way. As stated above, there is not any landscaping near the comers of the
11
4)
intersection. When considering 2-way Stop or Yield signs, typical engineering practice is to
determine the safe approach speed for the direction to be controlled. If a motorist must slow
down to lower than 15mph when approaching an intersection because of a sight obstruction, Stop
signs should be used rather than Yield signs. Else, Yield signs should be used.
For this case, the safe approach speed exceeds 15mph for the direction to be controlled since
there is not any landscaping causing a severe sight obstruction. Therefore, 2-way Stop signs are
not recommended at this intersection.
Yield Signs
At intersections where a full stop is not necessary at all times, consideration should be given to
using less restrictive measures such as Yield signs. Yield signs assign right-of-way to traffic
when the normal right-of-way rule appears to not be effective. 1 accident in the past 5 years does
not indicate a significant problem. The speed data, however, shows that because of the proximity
of the homes and landscaping to the intersection, motorists may not have enough time to see
other vehicles on the cross street, react and stop before reaching the intersection. Motorists
controlled by Yield signs would need to slow down before reaching the intersection resulting in a
shorter distance to come to a full stop if necessary. Finally, when installed, Yield signs should
be placed on the minor street. Since the traffic volume is similar on both streets, Staff reviewed
the traffic control signs on adjacent intersections and the recorded speeds on both streets to
determine the appropriate street to be given the right-of-way. Based on Staff's analysis, Yield
signs on Hi-Lusi Avenue are recommended at this intersection.
The Village Traffic Engineer recommends:
approval of Yield signs on Hi-Lnsi Avenue at Milburn Avenue.
