Subject:Installation of a 40 Kilometre Per Hour Speed Limit on Colonial Avenue, Scarborough Bluffs
Purpose:
To investigate the need for a 40 kilometre per hour speed limit on Colonial Avenue.
Funding Sources, Financial Implications and Impact Statement:
The $1000.00 (approximate) funds associated with the installation of the speed limit signs are available in the
Transportation Services 1999 budget, Account No. 100-TP10226.
Recommendations:
It is recommended that:
(1)the 40 kilometre per hour speed limit identified in Appendix 1 of this report be adopted; and
(2)the appropriate by-law be amended accordingly.
Council Reference/Background/History:
As a result of a request from a resident of Colonial Avenue, Transportation Services investigated concerns with regard to
speeding on this street.
Comments and/or Discussion and/or Justification:
Colonial Avenue is a residential collector road that runs between Bellamy Road South and McCowan Road. The speed
limit is currently 50 km/h. A park exists on Colonial Avenue and appropriate warning signs are posted in advance of this
location.
Speed studies were conducted on Colonial Avenue on Wednesday, April 28, 1999. The following was recorded:

Application of the 40 km/h Speed Limit Warrant on Colonial Avenue indicates that the necessary criteria are met. The
speeds we recorded in our study would indicate that most motorists travel at speeds close to and below 50 km/h on this
street. Furthermore, there is a curve at the west end of the street, at which the recommended travel speed is 30 km/h, as
well as other curves in the road. Although chevron warning signs are posted for westbound traffic at this location, a
reduced speed limit is considered appropriate to attempt to reduce motorists' speeds.
Our review of the reported collision history for the period between January 1, 1996 and December 31, 1998 reveals two
collisions have been reported over the past three years. Neither of these collisions involving speeding.
Conclusions:
Based upon the existing conditions on the street, the volume of traffic and the speeds recorded, staff recommends that
Colonial Avenue be posted with a 40 kilometre per hour speed limit.
