TRAFFIC CONTROL CONDITIONS - ST. LEGER STREET &
WELLINGTON STREET NORTH
RECOMMENDATIONS:
That an all-way stop control be installed at the intersection of St. Leger Street and
Wellington Street North; and further,
BACKGROUND:
That the Uniform Traffic By-law be amended accordingly.
Transportation Planning has received a request to review the current traffic control conditions at
the intersection of S1. Leger Street and Wellington Street North.
As outlined in the City of Kitchener Municipal Plan, S1. Leger Street is designated as a minor
collector roadway between Victoria Street North and Guelph Street and as a local roadway west
of Guelph Street North, while Wellington Street North is designated as a secondary arterial
roadway.
At the present time, traffic on S1. Leger Street stops and yields right of way to traffic on
Wellington Street North, as outlined in the City of Kitchener Uniform Traffic By-law No. 2000-
159. Both roadways have an unposted speed limit of 50 km/h.
Transportation Planning, in an effort to address the right angle collision history at this location,
had, a number of years ago, installed secondary stop signs on the eastbound and westbound
approaches along with the lighting of the primary stop signs. The collisions still being
experienced at this location indicate that there is a need to further update measures to improve
traffic safety.
REPORT:
A traffic study was conducted for the intersection of S1. Leger Street and Wellington Street North
in order to address concerns related to vehicle 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 Ministry of Transportation.
The following chart outlines the all-way stop warrant calculation for the intersection of St. Leger
Street and Wellington Street.

For the installation of an all-way stop, the Arterial/Major Collector All-way Stop Warrant requires
an eight-hour average hourly volume of at least 500 vehicles per hour, a combined vehicular
and pedestrian volume on the minor street averaging 200 units per hour and a volume split that
does not exceed 70/30. The volume on the major street is defined as vehicles only and the
volume on the minor street includes all vehicles plus any pedestrians wishing to cross the major
roadway. An all-way stop can also be warranted if the intersection experiences an average of at
least four (4) collisions, preventable by the installation of an all-way stop, per year over the past
three (3) years.
At this intersection the average hourly volume was recorded at 594 vehicles for all approaches,
the combined vehicular and pedestrian volume on the minor street average was recorded at 144
units per hour with 22 percent of the total approaching traffic on St. Leger Street versus 78
percent on Wellington Street North. As a result, this intersection does not meet the warrant for
an all-way stop based on intersection volume on the minor approach and on the volume split.
However, over the past three (3) years (September 2002 to September 2005), there has been
twelve (12) motor vehicle collisions preventable through the installation of an all-way stop
control at the intersection of St. Leger Street and Wellington Street North.
These collisions are occurring, in part, due to vehicular traffic's perception of available gap time.
The collision history at St. Leger Street and Wellington Street North shows that ten (10) of the
twelve (12) collisions were vehicles on St. Leger Street failing to yield right of way to traffic on
Wellington Street and two (2) were vehicles failing to stop on St. Leger Street. The installation of
an all-way stop would help to eliminate these types of collisions. As a result, this intersection is
warranted for the installation of an all-way stop control based on the collision history.
In 2004, Transportation Planning installed an all-way stop control at the intersection of Duke
Street and Wellington Street. This intersection has similar geometrics and traffic volumes to the
2
intersection of St. Leger Street and Wellington Street. While the intersection of Duke Street and
Wellington Street was warranted based on collision history with an average of 4.67 collisions
per year occurring over three (3) years before the all-way stop control installation, there have
been zero (0) collisions at this location since the installation of all-way stop. This confirms the
benefits of an all-way stop control installation under the appropriate conditions. Therefore, it is
recommended that the use of an all-way stop control at the intersection of St. Leger Street and
Wellington Street would assist in improving traffic operating conditions.
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 St. Leger street and Wellington Street North.
FINANCIAL IMPLICATIONS:
The approximate cost for the installation of the all-way stop control and to appropriately sign the
roadway is $1000, including materials and installation and will be taken from the existing sign
maintenance budget.
