Traffic Concerns, Lake Shore Boulevard West at
Forty First Street/Brow Drive (Lakeshore-Queensway)
The Etobicoke Community Council recommends the adoption of the following report
(February 17, 1999) from the Director, Transportation Services, District 2:
Purpose:
To address the concern of Long Branch Go Train users with respect to the traffic volumes
within the intersection of Lake Shore Boulevard West and Forty First Street/Brow Drive.
Funding Sources:
There are no funding implications associated with this report.
Recommendations:
It is recommended that traffic signals not be installed at the intersection of Lake Shore
BoulevardWest and Forty First Street/Brow Drive.
Background:
The Transportation Services Division - District 2, received correspondence/petition
(Attachment No.1) from Ms. Caroline S. Conklin, 61 Thirty Ninth Street, to investigate the
feasibility of installing traffic control signals at the intersection of Lake Shore Boulevard West
and Forty First Street/Brow Drive. A map of the area is Attachment No. 2.
A historical review revealed that the intersection of Lake Shore Boulevard West and Forty
First Street/Brow Drive had been investigated for traffic control signals in 1996. Traffic
signals could not be justified at that time due to the non-compliance of the minimum
requirements to warrant traffic control signals. Notwithstanding the aforementioned, the near
proximity of the existing traffic signals, at the TTC loop, does not favour the installation of
traffic control signals.
Currently, stop controls are located on the north and south approaches to the intersection of
Lake Shore Boulevard West on Forty First Street/Brow Drive.
To address Ms. Conklin's concerns the following information was obtained:
(1)24-hour automatic traffic counts at the north and south approaches to the intersection of
Lake Shore Boulevard West and Forty First Street/Brow Drive;
(2)Manual Turning Movement count at the intersection of Lake Shore Boulevard West at
Forty First Street/Brow Drive for the hours of 6:00 a.m.- 9:00 a.m., 11:00 a.m.- 12 noon and
3:00 p.m. - 7:00 p.m.; and
(3) Review of the three year (1995-1997) collision history.
Comments:
The results of an eight-hour traffic control signal study indicate that the minimum technical
requirements for the installation of traffic control signals are not satisfied at the intersection of
Lake Shore Boulevard West and Forty First Street/Brow Drive. The following table
summarized the technical warrant results:
|
Warrant |
Compliance |
| A |
Minimum Vehicular Volume |
66% |
| B |
Delay to Cross Traffic |
76% |
| C |
Collision Hazard |
26% |
For traffic control signals to satisfy the minimum requirements, any one of warrants A, B or C
must be satisfied to 100 percent or any two of the three warrants must be satisfied to 80
percent. Therefore, the vehicle volume at the intersection of Lake Shore Boulevard West and
FortyFirstStreet/Brow Drive do not warrant the installation of traffic control signals.
The spacing to the pedestrian signal at the TTC loop (138 metres) is significantly less than the
desired minimum spacing of 215 metres between traffic control devices. This minimum
spacing is the distance at which motorists can detect a signal or hazard and react in a safe
manner. Additionally, the minimum spacing is also necessary to prevent queued vehicles from
interfering with cross-street traffic when the traffic signal right-of-way changes.
Conclusions:
The installation of traffic control signals are not warranted at the intersection of Lake Shore
Boulevard and Forty First Street/Brow Drive, at this time.
