WARD(S) INVOLVED: Ward 5
DATE OF REPORT: November 21, 2014
REPORT NO.: INS-14-093
SUBJECT: All-Way Stop Control - Bridlewreath Street @ Mount Laurel
Crescent/Donnewerth Drive
RECOMMENDATIONS:
That an all-way stop be installed at the intersection of Bridlewreath Street and
Mount Laurel Crescent/Donnewerth Drive; and further,
That the Uniform Traffic Bylaw be amended accordingly.
BACKGROUND:
Transportation Services has received a number of requests to review the existing traffic
control at the intersection of Bridlewreath Street and Mount Laurel
Crescent/Donnewerth Drive. The request cited concerns with poor sightlines of vehicles
approaching Mount Laurel Crescent on Bridlewreath Street. These concerns are further
exasperated by the downslope of Bridlewreath Street as it approaches Mount Laurel
Crescent. It was requested that an all-way stop be considered to control traffic at this
intersection.
REPORT:
According to the City of Kitchener's Official Plan, Bridlewreath Street, Mount Laurel
Crescent and Donnewerth Drive are all designated as local roadways. At present time,
traffic on Mount Laurel Crescent/Donnewerth Drive stops and yields right of way to
traffic on Bridlewreath Street.
In response to the request, a traffic study was conducted for the intersection of
Bridlewreath Street and Mount Laurel Crescent/Donnewerth Drive on October 17,
2013. The results of the study were compared to the City of Kitchener's all-way stop
warrant requirements. These requirements are a set of guidelines based on the all-
way stop warrants established by the Ministry of Transportation of Ontario and the
Institute of Transportation Engineers. The results are as follows:
4 - 1
All-Way Stop Warrant Analysis
Bridlewreath Street at Mount Laurel Crescent/Donnewerth Drive
Warrant Factors - "4-Leg" Intersection Results Warrant Met
The total vehicle volume on all
intersection approaches averages 250 123 NO
vehicles per hour for each of any eight
hours of the day,
and
The volume split does not exceed 65/35 59/41 YES
for a four-way control for the same hour,
or
Collisions within a 12 month period
averaged over 36 consecutive months 0.67 per year NO
susceptible to correction by an All Way (Warrant Value=4)
Stop
All-Way Stop Warranted NO
As the results indicate above, this intersection does not meet the warrant for an all-way
stop based on traffic volumes.
Bridlewreath Street runs in an east/west direction, with Mount Laurel Crescent serving
as the north approach to this four-legged intersection. Bridlewreath Street runs downhill
as it approaches Mount Laurel Crescent/Donnewerth Drive as well as curving slightly
prior to the intersection. Based upon the characteristics of Bridlewreath Street at this
intersection, Transportation Services staff measured sight lines for traffic accessing
Bridlewreath Street from Mount Laurel Crescent.
The Geometric Design Guide for Canadian Roads recommends a minimum of 75
meters of stopping sight distance for roadways similar to Bridlewreath Street.
Measurements taken from Mount Laurel Crescent indicate that 65 meters of visibility is
provided on Bridlewreath Street. Therefore, sight lines at the intersection are
insufficient, creating safety concerns for pedestrian and vehicular traffic. With the
installation of an all-way stop, traffic would be forced to stop at all legs of the
intersection and visibility constraints should no longer be a concern.
Resultantly, based on the geometrics of Bridlewreath Street at this intersection and in
the interest of pedestrian and traffic safety, Transportation Services is recommending
that an all-way stop be installed at the intersection of Bridlewreath Street and Mount
Laurel Crescent/Donnewerth Drive.

ALIGNMENT WITH CITY OF KITCHENER STRATEGIC PLAN:
This initiative falls under the Community Priority of Quality of Life. "Work with partners,
including all orders of government, to create a culture of safety in our community." By
working with the neighbourhood, traffic control concerns have been addressed.
FINANCIAL IMPLICATIONS:
The approximate cost for the installation of an all-way stop at Bridlewreath Street and
Mount Laurel Crescent/Donnewearth Drive is $1,300, including materials and
installation and will be taken from the existing sign maintenance budget.
COMMUNITY ENGAGEMENT:
INFORM — This report has been posted to the City's website with the agenda in
advance of the council / committee meeting.
CONSULT — This recommendation has been communicated with the local Ward
Councillor.
