Works and Parks Committee, at its meeting held on December 1, 1997, received a request to determine the feasibility of installing an all-way stop control at the intersection of Haverson Boulevard and Donald Avenue and passed the following motion:

The present geometric layout of the intersection is a "T" type design.

Donald Avenue is classified as a local roadway under the City of York Official Plan. The street is presently designated in a one-way westbound direction between Haverson Boulevard and Silverthorn Avenue. The legally prescribed speed limit on this portion of the roadway is 40 km/h.

Haverson Boulevard is classified as a collector roadway under the City of York Official Plan, extending from Dunraven Drive to Commodore Avenue. Haverson Boulevard provides two-way vehicular traffic flow in a north and southbound direction. The legally prescribed speed limit on this roadway is 40 km/h.

Presently, the intersection is under stop control on Donald Avenue for westbound vehicular traffic.

To ensure the overall effectiveness and safety of all-way stop controls, established warrant criteria are utilized in analyzing the eight hour turning movement data to determine if the warrants are justified.

In order for an intersection to be warranted for an all-way stop control, at least one of the five warrant criteria must be fulfilled one hundred percent. A recent study of the intersection revealed the following results:

Intersection Safety Stop Study Warrant

(a) a total vehicle volume on all intersection

approaches exceeding 500 vehicles per

hour for any eight (8) hours of the day;

7 - 8 a.m. 79 No

8 - 9 a.m. 79 No

10 - 11 a.m. 89 No

11 - 12 p.m. 80 No

1 - 2 p.m. 80 No

2 - 3 p.m. 113 No

4 - 5 p.m. 127 No

5 - 6 p.m. 171 No

(b) a volume split of 70/30 or greater than 97/3 No

30% for the minor street;

(c) a combined vehicular and pedestrian 0 No

volume on the minor street exceeding

200 per hour with an average pedestrian

delay of 30 seconds or more;

(d) average 4 or more collisions per year for 0 No

a three year period subject to relief through

multi-way stop control;

(e) minimum traffic control signal warrants are 0 No

satisfied but cannot be implemented

immediately.

As the study results conclude an all-way stop control is not warranted at the intersection of Haverson Boulevard and Donald Avenue, and is therefore not recommended.

Committee may wish to ignore the warrant criteria results and approve the installation of an all-way stop control within the intersection of Haverson Boulevard and Donald Avenue.

None required.

Based on the study results an all-way stop control is not warranted and therefore not recommended at the intersection of Haverson Boulevard and Donald Avenue.
