INTERSECTION OF WELLINGTON STREET AND GEORGE STREET
BOWMANVILLE, REQUESTED ALL-WAY STOP
Recommendations:
It is respectfully recommended that the General Purpose and Administration Committee

Report #EGD-018-08

1.0 BACKGROUND
1.1 In response to a recent request from the community staff have undertaken a
study to determine whether an all-way stop at the intersection of Wellington
Street and George Street is warranted. Our findings and recommendations are
detailed in this report.
2.0 COMMENT
2.1 ODeratina SDeeds
On November 21, 2007, staff used the municipal radar gun to accurately record
and calculate average vehicle operating speeds of through traffic on Wellington
Street. The results showed an average speed of 44.1 kmlhr in a maximum 50
km/hr zone. The average speeds on George Street would also be well below the
regUlatory speed limit to the south, due to the short distance to the stop sign at
Church Street. The curve to the north of the intersection also reduces vehicular
speeds.
2.2 Motor Vehicle Collision Historv
Despite the low volume and local nature of the roadway there have been nine
MVC's in the last five years, the details of which are shown below:
2007 2 did not stop
1 did not yield
2006 2 did not stop
1 did not yield
2005 1 impaired
1 did not yield
2004 None
2003 1 did not stop

Clarinaton Wide MVC Historv
Motor vehicle collisions occur on a daily basis, usually on clear sunny days and
are generally attributed to driver error rather than roadway design or
maintenance issues. Motor vehicle collisions occur on straight stretches of
roadways, 2 way stops, all way stops, and traffic signals.
Year # of MVC
(Clarington Roads only, excludes Regional Roads/private property)
2004 350
2005 426
2006 349
2.3 Intersection Review Based on AII-Wav Stop Volume Warrants
In the Official Plan, Wellington Street and George Street are both local roadways
which are intended to move traffic between low volume local streets and towards
higher volume arterial roadways.
During 2005, Engineering Services worked closely with the Clarington Traffic
Management Advisory Committee (CTMAC) to modify the provincial warrant for
all-way stops, creating an in-house warrant that is more applicable to Clarington
roadways. The in-house modified warrant structure makes it less stringent/more
permissive for collector and local roadways to meet warrants for an all-way stop
by accepting lower traffic volumes, fewer peak hours and giving more recognition
to unsupervised pedestrian crossings.
These modified warrants are intended as a more relaxed guide for staff to
evaluate intersections in an unbiased, uniform manner so that they can then
make recommendations to Council. The warrants also provide Council with the
assurance that the municipality is attempting to work with its residents in a
consistent manner to balance efficient transportation with the needs of the local
neighbourhood.
Report #EGD-018-08

Using the new modified warrants during early 2007, staff recommended the
implementation of all-way stops at the intersections of Sandringham Drive and
Claret Road; Pebblestone Road at Trulls Road and Trulls Road at Avondale
Drive where intersections with higher vehicle volumes, pedestrian activity or
collisions would benefit from implementation of additional traffic controls.
As a result of the traffic study, it was determined that the average number of
vehicles at the intersection of Wellington Street and George Street is only 52% of
the already reduced warrant level. Furthermore, a review of the history of MVC's
at this intersection already shows a pattern towards charges of "did not stop" ,
"did not yield". The use of an unwarranted all-way stop at this location is unlikely
to address the factors that resulted in these charges and may in fact present an
additional safety hazard.
2.4 ProDosed ImDrovements
As a proactive measure we recommend the installation of no parking signs near
the intersection to ensure that ideal sight line conditions are not compromised by
those who may choose to park too close. These signs will be installed under
general terms ofthe traffic by-law 91-58 and no amending by-law is required to
implement the postings.

3.0 CONCLUSION
3.1 Staff, working with the CTMAC, developed a modified all-way stop warrant policy
to be used during intersection reviews by staff. This policy lowered the average
intersection volume requirements for an all-way stop on local roadways from the
Provincial figure of 350, to only 250, but this intersection only has 131 or 52% of
the reduced warrant and so an all-way stop is unwarranted.
Driver error has the potential to occur at any time, in a variety of lighting and
weather conditions and is not effectively mediated by all-way stops. The
introduction of an all-way stop at this unwarranted location is not recommended
but the intersection of Wellington Street and George Street will be carefully
monitored by staff and measures deemed necessary to reduce driver error will be
initiated where appropriate.
