Subject:Proposed Installation of Traffic Control Signals
Dundas Street West and Mabelle Avenue
Kingsway Humber; Councillors Gloria Lindsay Luby, Mario Giansante
Purpose:
To propose the installation of traffic control signals at the intersection of DundasStreetWest and Mabelle Avenue,
coincident with the removal of the existing pedestrian crossover (PXO) located approximately 30 metres east of Mabelle
Avenue near Cabot Court.
Funding Sources:
The funds associated with new traffic signal installations are contained in the Works and Emergency Services Capital
Program under Project No. C-TR031. In 1999, $1.6 million has been allocated for new traffic control signal installations.
The estimated cost of the installation of traffic control signals at the intersection of Dundas Street West and Mabelle
Avenue, including the removal of the existing PXO, is $80,000.00 which can be accommodated in the budget allocation.
Recommendations:
It is recommended that:
(1)traffic control signals be installed at the intersection of Dundas Street West and MabelleAvenue;
(2)coincident with the traffic control signal installation, the existing pedestrian crossover located approximately 30 metres
east of Mabelle Avenue be removed; and
(3)the appropriate City Officials be requested to take whatever action is necessary to give effect to the foregoing,
including the introduction in Council of any bills that may be required.
Background:
This location was investigated at the request of Councillor Gloria Lindsay Luby. The Councillor requested that staff review
the feasibility of relocating the existing traffic control signals on Dundas Street West and Royalavon Crescent to the
intersection of Dundas Street West and Mabelle Avenue. A similar request was also received from Mitch Stambler,
Manager of Service Planning with the Toronto Transit Commission, to facilitate the implementation of a westbound bus
service on Mabelle Avenue during peak weekday periods.
Discussion:
Dundas Street West in the vicinity of Mabelle Avenue is a four-lane arterial road with a two-way 24hour traffic volume of
approximately 27,600 vehicles per day. Adjacent traffic control signals are located 210 metres to the west at Royalavon
Crescent and 260 metres to the east at Burnhamthorpe Road/Cordova Avenue. A PXO is located 30 metres east of Mabelle
Avenue. Furthermore, six metered parking spaced are located on the north side of Dundas Street West, opposite Mabelle
Avenue.
An eight hour traffic control signal warrant study was conducted and revealed that traffic control signals are technically
warranted. The results are listed below:
| Warrant |
Compliance |
| (1) Minimum Vehicular Volume |
53 percent |
| (2) Delay to Cross Traffic |
100 percent |
| (3) Collision Hazard |
53 percent |
Either Warrant 1 or Warrant 2 should be 100 percent satisfied or any two of the three warrants should be 80 percent
satisfied to satisfy the minimum technical requirements for the installation of traffic control signals. The "Collision Hazard"
warrant is based on the number of collisions that occurred at the intersection in a three-year period which were potentially
preventable by the installation of traffic control signals.
Collision statistics provided by the Toronto Police Service indicate eight collisions over the three-year period from January
1, 1995 to December 31, 1997 that were potentially preventable by the installation of traffic control signals. Based on the
above information, the technical warrants for the installation of traffic control signals are met.
An eight hour traffic control signal warrant study was also conducted for the existing traffic control signals located at the
intersection of Dundas Street West and Royalavon Crescent to determine if this location continues to meet the technical
warrants for traffic control signals. The results of that study revealed that the subject traffic control signals remain
warranted, and as such, will not be removed.
The installation of traffic control signals at the intersection of Dundas Street and Mabelle Avenue will necessitate the
removal of six parking metres on the north side of Dundas Street West, west of Cabot Court.
Dundas Street West is an arterial road, and the installation of traffic control signals will not have a significant impact on the
effectiveness of this arterial link within the network of arterial roads. Furthermore, the signals will provide benefits to all
road users in the immediate area.
Staff have contacted the Ward Councillors and both Councillors Lindsay Luby and Giansante do not object to the proposed
installation of traffic control signals at this location.
Conclusions:
The installation of traffic control signals on Dundas Street West and Mabelle Avenue are technically warranted and would
provide benefits to all road users in the immediate area.
