(December 9, 1998) from the Director, Transportation Services, District 2:
Purpose:
To address the concern of an area resident with respect to the speed of vehicular traffic on
KingGeorges Road in the vicinity of Grenview Boulevard North.
Funding Sources:
There are no funding issues associated with this report.
Recommendations:
It is recommended that:
(1)all-way stop controls not be installed at the intersection of King Georges Road and
GrenviewBoulevard North; and
(2) the Toronto Police Services be requested to provide periodic enforcement of the 40 km/h
speed limit on King Georges Road in the area of Grenview Boulevard.
Background:
The Transportation Services Division, - District 2, received correspondence (AttachmentNo.1)
from Mr.Andrew Chorny, 62 King Georges Road, requesting all-way stop controls be
installed at the intersection of King Georges Road and Grenview Boulevard North. This
request is the result of his concern with respect to the excessive speed of vehicular traffic on
King Georges Road. A map of the area is Attachment No. 2.
To address Mr. Chorny's concern, the following information was obtained:
(1)a manual approach count conducted on Wednesday, June 10, 1998 at the intersection of
KingGeorges Road and Grenview Road North;
(2)a radar speed study conducted on Wednesday, June 10, 1998 on King Georges Road near
Grenview Boulevard North;
(3)review of the three year (1995-1997) accident history; and,
(4)intersection description, existing parking restrictions, sidewalks and land use.
Comments and Discussion:
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 neither arterial nor
major collector streets:
a)total 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.
(1)Manual Approach Counts
The following table summarizes the manual approach counts conducted at the intersection of
KingGeorges Road and Grenview Boulevard North on Wednesday, June 10, 1998.

The following observations and analysis were derived from the manual count:
(a)The total vehicle volume on all approaches for the highest hour, 5-6 p.m., is 312 vehicles.
This volume does not meet the minimum vehicular volume of 350 vehicles necessary to fully
satisfy the volume warrant.
(b)The balance of flow for the highest hour recorded is 69/31, which does not meet the
volume split warrant (65/35) for a four-way control.
Notwithstanding the aforementioned, the geometry of the intersection of King Georges Road
and Grenview Boulevard North does not favor an all-way stop operation. The centre lines of
the north and south approaches are offset 13.5 meters to each other. The Manual of Uniform
Traffic Control Devices clearly states that all-way stop controls should not be used at
intersections that are offset, poorly defined or geometrically substandard.
(2)Radar Speed Studies
Radar speed studies conducted on King Georges Road, near Grenview Boulevard North,
between 7-9 a.m. and 4-6 p.m. revealed an 85th percentile speed of 47 km/h.; the legal speed
limit on this roadway is 40 km/h.
(3)Accident Analysis
An accident review for the period January 1, 1995 to December 31,1997 revealed one
reportable accident at the intersection of King Georges Road and Grenview Boulevard North.
The collision was of angle type that occurred when a northbound vehicle failed to stop and
struck a westbound vehicle.
(4)Intersection Description
Parking Regulations: No Parking Anytime on the south side of King Georges Road between
PrinceEdwardDrive and Royal York Road, the north side of King Georges Road between
GrenviewBoulevard and Royal York Road, and the west side of Grenview Boulevard between
the parking meter zone and Strath Avenue.
Lane Configuration: One lane in each direction.
Speed Limit: 40 km/h on both roadways
Through Street: King Georges Road
Sidewalks: Both sides of the through and stop streets.
Land Use: R1 Residential (single)
Conclusions:
Traffic conditions at the intersection of King Georges Road and Grenview Boulevard North
do not meet the minimum requirements of the Ministry of Transportation of Ontario warrants
for all-way stop controls. Furthermore, the intersection geometry does not favor an all-way
stop operation at this location.
The results of the radar speed study does indicate a speeding problem on King Georges Road
in the area of Grenview Boulevard.
