To:Chairman and Members of the Scarborough Community Council

From:Gary H. Welsh, Director, Transportation Services, Works and Emergency Services

Subject:Traffic Concerns on Haileybury Drive, Scarborough City Centre

Purpose:

To review the impact of the installation of all-way stop controls at various locations on Haileybury Drive on traffic speeds and volumes on this street.

Funding Sources, Financial Implications and Impact Statement:

Not Applicable.

Recommendations:

It is recommended that:

(1)the existing all-way stop controls remain on Haileybury Drive; and

(2)a copy of this report be sent to the Toronto Police Services, 41 Division requesting that they review our all-way stop compliance and speed study results and take whatever action they deem appropriate.

Council Reference/Background/History:

As a result of concerns of residents of Haileybury Drive, with regard to speeding on this road, Transportation Services staff reviewed the need for all-way stop controls on Haileybury Drive. Our study results revealed incidents of excessive speeding and staff recommended police enforcement of the 40 kilometre per hour speed limit. As the residents' concerns were expressed in a petition, staff prepared a report to Community Council for the meeting on June 24, 1998. At this meeting, Community Council recommended that all-way stop controls be installed on Haileybury Drive at the intersections with Arnprior Road, Shediac Road and Penetang Crescent. Staff were also directed to review this location to determine the impact on traffic and report back to Community Council in six months' time on the results of our review.

Comments and/or Discussion and/or Justification:

Haileybury Drive is a residential road located west of Brimley Road and south of Lawrence Avenue. A 40 kilometre per hour speed limit is posted on this road along with appropriate School Area signs for Hunter's Glen Junior Public School. The all-way stop controls on Haileybury Drive at Arnprior Road, Shediac Road and Penetang Crescent were installed on August 19, 1998.

All-Way Stop Compliance:

To determine the compliance with the all-way stop controls on Haileybury Drive, studies were conducted at three locations on Tuesday, December 8, 1998 and Wednesday, December 9, 1998. We recorded the following:

Typically, at many all-way stop locations, we do observe that a small percentage of motorists will not come to a full stop or will take advantage of the right-of-way rule. This non-compliance is exacerbated when there is very little traffic on the minor street to create any conflicts, as is the case at these location. Fortunately, most of these motorists will enter the intersection with caution.

As expected, most of the stop sign violations occur by motorists on Haileybury Drive. The motorists who do disobey the stop signs appeared to be well aware of what they were doing as the visibility of the stop signs is good on all approaches.

Traffic Speed and Volume:

Additional speed and volume studies were also conducted on Haileybury Drive. The following table compares our study results, on Haileybury Drive, north of Canzone Drive, before and after the installation of the all-way stop controls.

During the follow-up we recorded lower traffic volumes and speeds on Haileybury Drive. We speculate that the decrease in volume could be attributed to motorists using other streets in the community to access Brimley Road. This decrease in volume, on an already low volume road, would have little impact on the street.

The decrease in average speeds can be attributed to the numerous stops along Haileybury Drive. The disadvantage of the numerous stops is that this does result in motorists disobeying the stop signs, however, as traffic volumes are low, the total violations are also minimal. Since the installation of the stops signs, we have not received any objections to their installation.

Collision History:

To update the collision history on Haileybury Drive, we reviewed the reported collisions for the almost four year period from January 1, 1995 to November 30, 1998. During this time period, eight collisions occurred on Haileybury Drive. Only one of these collisions was related to speeding and occurred at the curve on Haileybury Drive and Deerfield Road.

Conclusions:

Since the installation of the all-way stops on Haileybury Drive the overall speeds and traffic volumes on the road have reduced. Unfortunately it has also resulted in stop sign disobedience. We will request that the police review our study results and take whatever action they deem appropriate.
