Traffic Amendments in the Rosewood Subdivision
Ward 17 - Scarborough Agincourt
The Scarborough Community Council recommends the adoption of the following report (May 13, 1998)
from the Director of Road and Traffic Services, Scarborough, subject to adding thereto the following new
Recommendation No. (3) and renumbering the remaining recommendation accordingly:
A(3)an all-way stop control sign be installed at the intersection of Valdor Drive and Cleadon Road:@ :
Purpose:
To present the information relating to a 40 kilometre per hour speed limit on Montezuma Trail in conformance
with the former Scarborough Council Speed Limit Procedure and to investigate the need for stop signs on, and on
the streets intersecting Cleadon Road.
Funding Sources, Financial Implications and Impact Statement:
The $700.00 (approximate) funds associated with the installation of the speed limit signs and stop signs are
available in the Road and Traffic Services 1998 Budget, Account No. 20000-70200-72240.
Recommendations:
It is recommended that:
(1)the 40 kilometre per hour speed limit identified in Appendix 1 of this report be adopted;
(2)the stop signs identified in Appendix 2 of this report be adopted; and
(3)the appropriate by-laws be amended accordingly.
Council Reference/Background/History:
At the request of Scarborough Agincourt Councillors Doug Mahood and Sherene Shaw, Road and Traffic Services
staff is presenting this report to enact a 40 kilometre per hour speed limit on Montezuma Trail without any staff
recommendations. Staff did, however, investigate the intersections of Cleadon Road and Kennaley Crescent, and
Cleadon Road and Valdor Drive for all-way stops at the request of the Councillors.
Discussion:
Both Cleadon Road and Montezuma Trail are residential roadways located west of Brimley Road and south of
McNicoll Avenue. Both roads currently contain 50 kilometre per hour speed limits.
40 Kilometre Per Hour Speed Limit:
Based on the former Scarborough Council adopted 40 Kilometre Per Hour Speed Limit Procedure, speed study
results were not applied to the 40 Kilometre Per Hour Speed Limit Warrant. The adopted procedure allows a
councillor to propose a speed limit of 40 kilometre per hour on any former Scarborough road with a pavement
width of 9.7 metres or less.
All-Way Stop Control:
The justification for the installation of an all-way stop control is based on a technical warrant established by the
Ministry of Transportation of Ontario (MTO), and adopted as the City Policy by the former Scarborough Council.
Traffic studies conducted on Wednesday, April 8, 1998 on Cleadon Road at the following two intersections
produced the following results which illustrate that the Warrant's vehicle volume requirements are not satisfied at
these locations:

We must highlight that with the recorded vehicle volume percentage splits for the major/minor roads at these
intersections, we would anticipate a high level of stop sign disobedience if stop signs were installed on Cleadon
Road as motorists would rarely encounter traffic on the minor road.
Therefore, since the Warrant=s vehicle volume requirements are not satisfied, all-way stop controls are not
warranted at these intersections.
All-Way Stop Control Integrity:
It is important to maintain the integrity of our All-Way Stop Control Warrant. The following outlines the main
reasons why the installation of unwarranted all-way stop controls are not recommended:
(a)the stop sign is one of the most valuable and effective control devices available to the Traffic Engineering
Profession, when used at the right location and under the right conditions;
(b)the installation of unwarranted stop signs as speed control devices often serves to irritate motorists, resulting in a
further increase in speeds to make up time for what they perceive as unnecessary delays; for this reason and as
stipulated in the All-Way Stop Control Warrant, it should not be used as a speed control device;
(c)most motorists are reasonable and prudent with no intention of maliciously violating traffic regulations;
however, when an unreasonable restriction is imposed, it does result in flagrant violations; in such cases, the stop
sign can create a false sense of security in a pedestrian and an attitude of contempt in a motorist; these two attitudes
can and often do conflict, ultimately making the intersection less safe for both pedestrians and motorists;
(d)the City has an obligation to provide services in an environmentally conscious manner; the installation of
unwarranted stop controls not only undermines the MTO Warrant but contributes to unnecessary fuel consumption
and higher levels of noise and air pollution; these pollutants most specifically impact those residents in the
immediate vicinity of the intersection; and
(e)the All-Way Stop Control Warrant is incorporated in the Manual of Uniform Traffic Control Devices, therefore,
as the installation of all traffic controls is governed by this Manual, the installation of an unwarranted control could
potentially place the City in a position of liability if it was determined to be a factor in a collision.
During the two study periods, no conflicts were observed between motorists or between motorists and pedestrians
at these intersections.
Also, if all-way stop controls were installed on Cleadon Road, motorists would now be required to stop in front of
homes adjacent to the affected intersections. In the past, we received requests from residents for the removal of
stop signs in front of their homes. Some residents feel that these controls will not only adversely affect the
appearance of their homes but they will also lose some privacy due to vehicles continually stopping in front of their
homes.
Nonetheless, currently no stop signs are posted at either intersection. As our studies reveal that both Kennaley
Crescent and Valdor Drive are clearly the minor streets, stop signs where they intersect Cleadon Road would define
the right-of-way at these intersections.
Collision History:
A three-year review of the reported collision history, January 1, 1994 to December 31, 1996 reveals no (0)
collisions have occurred at the intersections of Cleadon Road and Kennaley Crescent, or Cleadon Road and Valdor
Drive.
Conclusions:
Based on the Scarborough Council adopted 40 Kilometre Per Hour Speed Limit Procedure, this report proposes the
installation of a 40 kilometre per hour speed limit on Montezuma Trail.
Although all-way stop controls are not warranted or recommended on Cleadon Road at either Kennaley Crescent or
Valdor Drive, we do propose stop signs on both of the minor street approaches to define the right-of-way at these
intersections.
