Subject:All-Way Stop Study:
King Georges Road and Grenview Boulevard North
(Kingsway-Humber)
Purpose:
To address the concern of an area resident with respect to the speed of vehicular traffic on King Georges 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 Grenview Boulevard 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. TheManualofUniformTrafficConrolDevices 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.
