Installation of All-Way Stop Sign - Iona Avenue and

Keystone Avenue (East Toronto)

The Toronto Community Council recommends that an all-way stop sign be installed at the intersection of Iona Avenue and Keystone Avenue.

The Toronto Community Council submits the following communication (November 30, 1998) from Councillor Jakobek:

There is currently a stop sign located at Iona Avenue northbound at Keystone Avenue. However, residents have signed a petition requesting an "all-way stop" at this intersection.

I attach a copy of the Report prepared by Works and Emergency Services which does not recommend an all-way stop sign be installed.

Residents are still insisting that an all-way stop sign be installed at this intersection. I am therefore requesting that Council approve the installation of an all-way stop sign at the intersection of Iona Avenue and Keystone Avenue.

Report (October 16, 1998) from the Director, Transportation Services District 1,

Works and Emergency Services, addressed to Councillor Jakobek

Further to my letter of September 18, 1998 regarding the above, Transportation Services staff have updated their traffic survey data on Keystone Avenue to assist in evaluating if the installation of speed humps on this section of Keystone Avenue is justified or if all-way "Stop" sign control at the intersection of Keystone Avenue and Iona Avenue is warranted.

Keystone Avenue between Cedarvale Avenue and Patricia Drive is a residential street operating two-way with a pavement width of 8.53 metres. Parking is allowed on both sides of the street.

The former City of Toronto Council, at its meeting on August 21, 1997 adopted, as amended, Clause 28 in City Services Committee Report No. 10 entitled Installation of Speed Humps on City Streets which sets out five primary criteria that must be satisfied when evaluating requests for speed humps. Specifically, one of the criteria stipulates that the street should carry a volume of between 1,000 and 8,000 vehicles per day to warrant the installation of speed humps.

Our speed and volume surveys on Keystone Avenue, between Cedarvale Avenue and Iona Avenue and between Iona Avenue and Petricia Drive conducted for a four day period from September 4 - 7, 1998 confirmed the findings of our earlier traffic survey in 1992, recording a maximum traffic volume of 530 vehicles daily. Accordingly, the installation of speed humps on Keystone Avenue is not numerically warranted.

The study showed that 24.1% exceeded the 40 kilometre per hour speed limit of which, 5.7% were recorded travelling at a rate of speed 11 kilometres per hour or more over the speed limit. These results are not unusual on a residential street. The volumes are, however, quite low.

Keystone Avenue and Iona Avenue form a T-type intersection and traffic operation is controlled by a "Stop" sign for northbound traffic on Iona Avenue at Keystone Avenue. We have evaluated this intersection for the installation of all-way "Stop" sign control against the criteria outlined in the Provincial Manual of Uniform Traffic Control Devices. Based on our assessment, the installation of all-way "Stop" sign control is not justified. Specifically, the two roadways do not have similar traffic volume/operating characteristics nor does the intersection show a high accident frequency (no accidents reported in the past 3 years).
