Subject:Stop Control Assessment:
Thirtieth Street and Rimilton Avenue
(Lakeshore - Queensway)
Purpose:
To evaluate the effectiveness of the current stop control operation at the intersection of Thirtieth Street and Rimilton
Avenue.
Funding Sources:
The funds associated with the installation of regulatory signs are contained in the Transportation Services Division's
Operating Budget.
Recommendation:
It is recommended that the intersection of Thirtieth Street and Rimilton Avenue continue to operate with stop signs
controlling northbound and southbound traffic.
Background:
City Council, at its meeting on June 3, 1998, adopted a report (item 4) from the former Commissioner of Works, Etobicoke
District titled, "Proposed Installation of All-Way Stop Controls - Thirtieth Street and Rimilton Avenue". The report
(Attachment No. 1) recommended in part that
1.) all-waystop controls not be erected at the intersection of Thirtieth Street and Rimilton Avenue;
2.) the stopsigns controlling eastbound and westbound traffic be relocated to control northbound and southbound traffic on
Thirtieth Street; and, 3.) the effectiveness of this initiative be evaluated in six months. A map of the area is Attachment No.
2.
Comments:
To assess current operating conditions at the intersection of Thirtieth Street and Rimilton Avenue, staff of the District
Transportation Services Division observed this location in terms of stop compliance, conducted a radar speed study on the
through street (Rimilton Avenue), and reviewed the intersection collision history since the stop controls were removed
from Rimilton Avenue and erected on Thirtieth Street.
Observations at the intersection were conducted between the periods 7:30 - 9:00 a.m. and 2:30 -3:30 p.m. to coincide with
school commencement/dismissal times at FatherJohnRedmondSecondary School, 300 Valermo Drive. Driver compliance
of the stop controls was very good and no potential vehicle conflicts were observed.
The results of the radar study, conducted during the aforementioned periods, indicate an 85thpercentile speed of 50.5 km/h
on Rimilton Avenue. Given the legal speed limit on this roadway is 50 km/h, vehicle speeds are within acceptable levels.
A review of the collision history at the intersection of Thirtieth Street and Rimilton Avenue reveals that one reportable
accident occurred between July 27, 1998 (the date the stop signs were relocated), and December 31, 1998. The accident
occurred when a southbound vehicle failed to stop and struck a westbound vehicle. Although the driver of the southbound
vehicle reported that he did not see the stop control, a subsequent site investigation indicated that the stop sign was in
excellent condition and was not obstructed in any way.
Conclusions:
Based on the observations made at the intersection, compliance of the existing stop controls is very good. Although a
collision was reported since the stop controls were relocated from RimiltonAvenue to Thirtieth Street, this incident can be
contributed to the driver's inattentiveness.
It is evident from the radar studies that the removal of the stop controls on Rimilton Avenue has not had a negative impact
on the speed of traffic on this roadway.
