The Etobicoke Community Council submits the following report (May 6, 1998) from the Commissioner of Works,
Etobicoke District:
Purpose:
To address concerns with respect to the speed and volume of vehicular traffic at the intersection of St. Georges Road and
Wimbleton Road, and in the vicinity of Kingsway College School.
Funding Sources:
The funds associated with the installation of the appropriate warning signs are allocated in the Transportation
Department=s 1998 Operating Budget.
Recommendations:
It is recommended that:
(1) all-way stop controls not be installed at the intersection of Wimbleton Road and St. Georges Road;
(2)the Toronto Police Service be requested to consider the introduction of the School Crossing Guard Programme or the
School Patroller Programme on Wimbleton Road immediately in front of Kingsway College School, in consultation with
the school administration;
(3)subject to the outcome of the Toronto Police Service review of the pedestrian crossing conditions on Wimbleton Road
in front of Kingsway College School, staff will examine the need for the implementation of alternative traffic management
measures in conjunction with the implementation of the preferred pedestrian crossing assistance programme, in
consultation with concerned residents, school administrators and the Toronto Police Service;
(4)a Ahidden intersection@ sign be installed on Wimbleton Road, south of St. Georges Road, for northbound traffic; and

Council Reference:
The Etobicoke Community Council, at its February 18, 1998, meeting, received a communication from Mr. I. Nishisato,
President, Humber Valley Village Residents= Association. In his letter, Mr. Nishisato raised concerns with respect to the
speed and volume of vehicular traffic at the intersection of St. Georges Road and Wimbleton Road, and in the vicinity of
Kingsway College School. The communication was referred to the Commissioner of Works with a request for a report. A
map of the area is Attachment No.1.
Comments and Discussion:
Wimbleton Road and St. Georges Road are classified as local roads. Each has a roadway width of approximately 7 metres,
providing one lane of traffic per direction. The posted speed limit on Wimbleton Road is 40 km/h; the speed limit on St.
Georges road is 50 km/h. There are no sidewalks on either of these roadways. The intersection of Wimbleton Road and
St. Georges Road has three municipal approaches to the north, south, and east. The west approach is the private driveway
to St. George=s-on-the-Hill Church. For purposes of this report, the intersection of Wimbleton Road and St. Georges Road
will include the church driveway and will be considered as an intersection with four approaches. Kingsway College School
is located on the west side of Wimbleton Road immediately north of Dundas Street West.
To assess traffic conditions at the intersection of Wimbleton Road and St. Georges Road, and on Wimbleton Road in front
of Kingsway College School, the following information was obtained:
(1)Turning movement counts, conducted on March 26, 1998, at the intersection of Wimbleton Road and St. Georges Road.
(2)Intersection Capacity Analysis: Wimbleton Road and St. Georges Road.
(3)Radar speed studies, conducted on March 26, 1998, on Wimbleton Road, mid-block between Dundas Street West and
St. Georges Road; St. Georges Road, mid-block between Wimbleton Road and Canterbury Road on October 7, 1997, and
March 26, 1998.
(4)A vehicle collision summary for the period January 1, 1995, to December 31, 1997.
The following chart summarizes the results of the turning movement counts undertaken on March 26, 1998, at the
intersection of Wimbleton Road and St. Georges Road.

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)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.
As noted in the turning movement count summary, the peak hour at this intersection is 8:00 a.m. to 9:00 a.m. The total
vehicle volume on all approaches during this hour is 295 vehicles and the vehicle volume split is 64/36. Although the
volume split does meet the warrant requirement, the vehicle volume fails to meet the minimum requirement necessary to
satisfy the vehicle volume warrant. Attachment No. 2 summarizes the peak hour turning movement data.
Intersection Capacity Analysis
The results of the capacity analysis for the intersection of Wimbleton Road and St. Georges Road indicate that this
intersection functions very efficiently at level of Service A, during the peak hour conditions. The intersection approach
delay to motorists is minimal and the potential for vehicular conflict is very low.
Notwithstanding the results of the vehicular volume study and capacity analysis, there are a number of conditions that must
also be addressed when considering the introduction of all- way stop controls at an intersection. The stop sign installation
guidelines provided in the Highway Traffic Act, Manual for Uniform Traffic Control Devices, indicate that All-Way Stop
Controls should not be used under the following conditions:
1.Where pedestrian protection, in particular school children, is a prime concern, as this concern can usually be addressed
by other means;
2.As a speed control device;
3.At intersections having less than three or more than four approaches;
4.At offset or poorly defined intersections;
5.On truck or bus routes unless in an industrial area where two such routes cross;
6.On multi-laned approaches where a parked or stopped vehicle on the right will obscure the stop sign;
7.Where traffic would be required to stop on grades;
8.As a method of deterring the movement of through traffic in a residential area;
9.Where visibility of the sign is hampered by curves or grades and a safe stopping distance of less than 100 metres exists;
and
10.Where any other traffic device controlling right-of-way is permanently in place within 250 metres, with the exception
of a Yield sign.
Three of these conditions are of concern at the intersection of Wimbleton Road and St. Georges Road: the roadway grade at
the intersection; the driver visibility of the intersection, and the safe stopping distance requirement on approach to the
intersection; and the intersection definition.
This intersection is located on a relatively steep grade. The installation of a stop control is not considered where grade is a
factor because it inhibits the ability of a driver to start and, more importantly, stop a vehicle on a grade, particularly during
inclement weather when pavement conditions are hazardous. The horizontal curve on the southbound approach and the
vertical curve on the northbound approach reduce a driver=s visibility of the intersection to approximately 70 metres, 25
metres below the recommended safe stopping distance of 100 metres. Compounding the visibility issue is the poor
definition of this intersection. Unlike more recently developed intersections where the roads are generally wider and curbs
and sidewalks have been constructed, these roads are narrow and treed or landscaped to the road=s edges reflecting the
more rural character of the neighbourhood. These features make the intersection less discernible to an approaching
motorist.
Grade becomes an even greater factor at this location when the sight distance to the intersection is reduced and the
intersection is poorly defined. The combination of these factors makes this intersection a poor candidate for the installation
of an all-way stop control. Requiring the drivers and pedestrians on St. Georges Road and the church driveway to stop and
yield the right-of-way to motorists on Wimbleton Road ensures that these conditions do not become a safety factor at this
intersection.
Pedestrian Activity/School Zone
During the study it was noted that on several occasions throughout the day a large number of students crossed Wimbleton
Road between the Kingsway College School and the playground located on the east side of the road. In September 1997,
staff, in consultation with the administration of the school, upgraded the school zone advanced warning signs on
Wimbleton Road, in front of the school. The pedestrian crossing issue was discussed at this time and staff referred the
school administration to the appropriate contact in the Toronto Police Service to discuss the merits of introducing the
School Crossing Guard and School Patroller Programmes at this location. Representatives of the police Community
Services-Education Unit met with the school administration and examined the pedestrian crossing activity in front of the
school. The police concluded that the use of school patrollers would be suitable at this location; however, the school did not
implement the programme. By virtue of recommendation (2) in this report, this issue will be forwarded to the Toronto
Police Service for consideration and the school=s administration will have the opportunity to re-examine this option.
There appears to be some question among area residents as to whether or not St. Georges Road is considered to be a school
zone. Only roads immediately adjacent to a school are considered to be school zones. The Manual of Uniform Traffic
Control Devices (MUTCD) clearly states that Awhere a school is contiguous to a highway or arterial street, it is considered
advisable to provide advance warning to motorists that they are approaching an area where children walk along, or may
cross, the roadway, and that they are required to exercise caution and foresight in proceeding through these areas.@ School
zones are denoted with blue and white signs displaying the silhouette of two school children. Based on the MUTCD
definition, Wimbleton Road is considered to be the school zone and a review of the area indicates that all the required
warning signs are in place.
Radar Speed Studies
Radar speed studies conducted on Wimbleton Road, mid-block between Dundas Street West and St. Georges Road, on
March 26, 1998, between the hours of 7:00-9:00 a.m., and 3:00-5:00 p.m. indicated an average speed of 39 km/h. The
average speed of vehicles recorded at this location that proceeded straight through the intersection of St. Georges Road was
40 km/h. Since the posted speed limit on this roadway is 40 km/h, these results are well within acceptable levels.
Radar speed studies conducted on St. Georges Road, mid-block between Wimbleton Road and Canterbury Road, on
October 7, 1998, between 7:00-10:00 a.m. and 3:00-5:00 p.m. indicated an average speed of 32 km/h. The results of the
study conducted on March 26, 1998, were consistent with results of the study completed on October 7, 1998. Vehicle
speeds on this roadway are well below the legal speed limit of 50 km/h.
Vehicle Collission Summary
The vehicle collision summary has indicated that one reportable accident occurred at the intersection of Wimbleton Road
and St. Georges Road during the past three years. It occurred on September 4, 1997, when a vehicle travelling westbound
on St. Georges Road struck a vehicle travelling southbound on Wimbleton Road at approximately 30 km/h. There were no
injuries or property damage, however, the driver of the westbound vehicle was charged with careless driving.
Conclusions:
Based on the results of these studies, the installation of all-way stop controls at this intersection cannot be recommended.
Traffic volumes at the intersection of Wimbleton Road and St. Georges Road do not meet the minimum requirements of the
Ministry of Transportation of Ontario all-way stop control warrants: the results of the radar speed studies clearly indicate
that motorists are driving in a safe and responsible manner on Wimbleton Avenue in this school zone, and on St. Georges
Road. Although an all-way stop control does strictly control right-of-way in an intersection it also affords road users the
ultimate level of access to an intersection in that pedestrians and motorists enjoy the benefit of priority access to an
intersection. The safety of a pedestrian or a driver lawfully entering an intersection cannot be compromised by challenging
the ability of a driver to stop a motor vehicle on a grade, particularly where visibility is a concern.
