Proposed Installation of All-Way Stop Controls:
Queen=s Plate Drive and Vice Regent Boulevard
The Etobicoke Community Council recommends the adoption of the following report (May 6, 1998) from the
Commissioner of Works, Etobicoke District.
Purpose:
To propose the installation of All-Way Stop Controls at the intersection of Queen=s Plate Drive and Vice Regent
Boulevard.
Funding Sources:
The funds associated with the installation of the appropriate regulatory signage are contained in the Transportation
Department=s 1998 Operating Budget.
Recommendations:
It is recommended that:
(1)all-way stop controls be erected at the intersection of Queen=s Plate Drive and Vice Regent Boulevard; and
(2)the attached by-laws (Attachments Nos. 1 and 2) receive Council approval.
Background:
The Transportation and Engineering Planning Division has received correspondence from Mr. Ernie Lynch of Lynch Fluid
Controls Incorporated, 55 Queen=s Plate Drive, Unit No. 2, (Attachment No. 3) requesting the installation of all-way stop
controls at the intersection of Queen=s Plate Drive and Vice Regent Boulevard. Mr. Lynch is concerned with the accident
frequency at this location. A map of the area is Attachment No. 4.
Comments and Discussion:
To assess traffic conditions at the intersection, the following information was obtained:
A.manual vehicular turning movement counts, conducted on December 2, 1997, at the intersection of Queen=s Plate Drive
and Vice Regent Boulevard;
B.automatic traffic counts recorded on December 9, 1997, at the intersection of Queen=s Plate Drive and Vice Regent
Boulevard;
C.radar Speed Studies, conducted on December 4, 1997, on Queen=s Plate Drive, east of Vice Regent Boulevard;
D.a review of the three year accident history; and
E.an intersection description, including existing parking restrictions and land use.
The Ministry of Transportation of Ontario has provided the following warrants for the installation of all-way stop controls
on roads and streets considered to be either arterial or major collector streets:
a)a total of vehicle volume on all intersection approaches must exceed 350 for the highest hour recorded; and
b)a volume split should not exceed 65/35 for a four-way control.

The following observations and analysis were derived from the manual count :
a)the total vehicle volume on all approaches for the highest hour (5:00 p.m.- 6:00 p.m.) is 236 vehicles, 114 or 33% short
of the required 350 vehicles. This volume does not satisfy the minimum vehicular volume requirement established by the
Ministry of Transportation of Ontario (MTO) for the installation of all-way stop controls.
b)the balance of flow for the highest hour recorded is 72/28, which does not meet the volume split warrant of 65/35 for
four way control.
B. Radar Speed Studies
Radar Speed Studies were conducted on Queen=s Plate Drive, near Vice Regent Boulevard, between the hours of
7:00 a.m.- 9:00 a.m. and 4:00 p.m.-6:00 p.m. The average speed and 85th percentile speed are 55 km/h and 64 km/h,
respectively. Since the speed limit on both roadways is 50 km/h, these results indicate that there is a speeding problem. A
request has been forwarded to Toronto Police Services for enforcement of the 50 km/h speed limit on Queen=s Plate Drive.
C. Accident Analysis
An accident analysis for a three year period revealed an average of three reportable accidents per year have occurred at the
intersection of Queen=s Plate Drive and Vice Regent Boulevard. All accidents were of angle impact type and would be
considered preventable through installation of all-way stop controls.
D.Intersection Description
No parking restrictions on Vice Regent Boulevard or Queen=s Plate Drive .
Lane Configuration: one lane in each direction
Speed Limit: Queen=s Plate Drive - 50 km/h
Vice Regent Boulevard - 50 km/h
Through Street: Queen=s Plate Drive
Stop Signs: Vice Regent Boulevard - oversized
Land Use: Commercial
Conclusions:
The use of oversized stop signs on Vice Regent Boulevard eastbound and westbound at Queen=s Plate Drive has had little
effect in reducing the frequency of collisions in the intersection. At present, the frequency of right angle collisions in the
intersection warrants the installation of all-way stop controls. The traffic volumes in this intersection do not currently
satisfy the Ministry of Transportation of Ontario All-way Stop Control Warrants, however, once the development potential
in the area has been realized, traffic volumes are expected to satisfy the necessary requirements. All-way stop controls at
this intersection will effectively regulate current and future traffic demand and reduce or eliminate the occurrence of right
angle accidents.
