Submitted By: John McBride, Director of Transportation Planning
Prepared By: Cameron Bevers, Traffic Technologist (741-2618)
Wards} Involved: Fairview-Gateway Ward (3)
Date of Report: 2007 July 11
Report No.: DTS 07-118
Subject: ALL-WAY STOP CONTROL -PIONEER DRIVE & BLACK
WALNUT DRIVE
RECOMMENDATIONS:
That an all-way stop control be installed at the intersection of Pioneer Drive and Black
Walnut Drive; and further,
That the Uniform Traffic By-law be amended accordingly.
BACKGROUND:
Transportation Planning has received a request to review the current traffic control conditions at
the intersection of Pioneer Drive and Black Walnut Drive. According to this request, drivers are
having difficulty negotiating the intersection safely because of overall traffic volumes at this
location and also due to the restricted sightlines on the northern approach to the intersection.
As outlined in the City of Kitchener Municipal Plan, both Pioneer Drive and Black Walnut Drive
are designated as minor collector roadways.
At the present time, traffic on Black Walnut Drive must stop and yield right-of-way to traffic on
Pioneer Drive as outlined in the City of Kitchener Uniform Traffic By-law No. 2000-159.
REPORT:
In response to this request, Transportation Planning has conducted traffic studies and a collision
analysis for the intersection of Black Walnut Drive and Pioneer Drive in order to address
concerns related to traffic and pedestrian safety. The results of the traffic study were compared
to the approved All-way Stop Warrant developed by Transportation Planning, which is a set of
guidelines based on the all-way stop warrants established by the Institute of Transportation
Engineers (ITE) and the Ontario Ministry of Transportation (MTO).
For the installation of an all-way stop control at a three-leg intersection, the Minor Collector
Roadway All-way Stop Warrant requires an average hourly volume of at least 250 vehicles per
hour for each of any eight hours of the day and a volume split that does not exceed 75/25, or
that the total vehicle volume on all intersection approaches exceeds 350 for the highest hour
and a volume split that does not exceed 75/25 for the same hour. An all-way stop can also be
warranted if the intersection experiences an average of at least three (3) correctable collisions
per year over the past three (3) years. A correctable collision is one whose occurrence may
have been prevented through the installation of an all-way stop control.

All-Way Stop Warranted? YES
The highest hour volume recorded at the intersection was 477 vehicles for all approaches,
which exceeded the minimum volume of 350 vehicles required to fulfill the highest hour volume
warrant. The intersection also satisfied the volume split during that same hour, as 31 percent of
approaching traffic was on Black Walnut Drive and 69 percent of approaching traffic was on
Pioneer Drive. The intersection therefore meets the warrant requirements for an all-way stop
control based on highest hour volume and volume split.
The average hourly volume was recorded at 345 vehicles for all approaches with 40 percent of
the total approaching traffic on Black Walnut Drive versus 60 percent on Pioneer Drive. As a
result, this intersection meets the warrant for an all-way stop control based on the average
hourly volume and volume split.
The installation of the all-way stop at the Pioneer Drive and Black Walnut Drive intersection will
allow traffic from Black Walnut Drive to access Pioneer Drive safely by requiring vehicles on
Pioneer Drive to stop at Black Walnut Drive. As well, this all-way stop installation will provide an
increased gap time for vehicular traffic turning left from Pioneer Drive onto Black Walnut Drive.
Therefore, it is expected that traffic operations within the intersection of Pioneer Drive and Black
Walnut Drive will be improved by the installation of an all-way stop at this intersection.
Therefore, in order to maintain a proactive approach to pedestrian and traffic safety,
Transportation Planning is recommending the installation of an all-way stop control at the
intersection of Pioneer Drive and Black Walnut Drive.
FINANCIAL IMPLICATIONS:
The approximate cost for the installation of the all-way stop control and to appropriately sign the
roadway is $750, including materials and installation and will be taken from the existing sign
maintenance budget.
