Report #EGD-017-07

1.0 BACKGROUND
1.1 The Engineering Services Department has been monitoring the area since 2003
when staff received a number of calls from residents requesting an all-way stop
due to increasing traffic volumes, pedestrian volumes and high operating speeds.
Many of the calls have been from parents of children who must cross Trulls Road
to attend either Good Shepherd Catholic Elementary School or Lydia Trull
Elementary Public School.
2.0 COMMENT
2.1 Vehicle Speeds
Operating speeds on Trulls Road near Avondale were checked by staff using a
radar gun and showed an average 61.2 km/hr in the posted 50 km/hr zone while
the adult crossing guard was not on duty. This higher than desired operating
speed occurs in part due to the road side environment of straight and level
alignment, 10m pavement width and some sections with rear yard fenced areas
rather than open to residential frontages.
2.2 Consideration of an AII-wav Stop
During 2005/2006 Engineering Services worked closely with the (CTMAC)
Clarington Traffic Management Advisory Committee to modify the Provincial
Warrant for all-way stops, creating an in-house warrant to make it more
applicable to Clarington roadways. The in-house modified warrant structure
makes it easier for arterial, collector and local roadways to meet warrants for an
all-way stop by accepting lower traffic volumes and giving more recognition of
unsupervised pedestrian crossings. These modified warrants are intended as a
more relaxed guide for staff to evaluate intersections in an unbiased uniform
manner to make recommendations to Council. It also gives Council the
knowledge 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.

Trulls Road is classed as an Arterial B Roadway connecting Durham Hwy 2 to
Durham Road 22 (Bloor Street). The arterial intersection volume warrant for an
all-way stop is difficult to reach and although not fully warranted at the present
time the numbers are close. The volumes required for arterial roadways are 500
vehicles per hour for the 8 study hours; however, under the more relaxed
guidelines staff can consider the 8 hour average. The study recorded an
average of 486 vehicles per hour over the 8 hours, and the volume split
requirements are satisfied. There were over 300 pedestrians crossing Trulls
Road during the 8 hour study with the majority of those being assisted by an
adult crossing guard. The peak period was 8:00-9:00 a.m. with an intersection
volume of 737 vehicles. Based on the existing average hourly volumes,
pedestrian activity and probability of the warrants being met within a short period
of time (1 year), staff would recommend that Council support the early
introduction of an all-way stop.
2.3 Timina of Installation
Although the intersection volumes are rising surprisingly there has only been 1
collision (during 2005) over the past 3 years. The intersection is operating at an
acceptable level of service with Trulls Road having the right-of-way and may
continue to operate safely for a number of years. If Council does support the
early introduction of an all-way stop, staff recommends that this change in right-
of-way take place in the spring of 2007 when weather conditions have improved
and pavement markings can be applied.
3.0 CONCLUSION
3.1 Engineering Services will support the residents' requests for the early
introduction of an all-way stop at the intersection of Trulls Road and Avondale
Drive based on existing and projected traffic volumes and have attached a
proposed by-law for Council's consideration.
