Phased Approach to Improving Rural All-Way Stop Controlled Intersection in Pelham, Ontario

This paper evaluates the effectiveness of several traffic control devices to improve safety and capacity conditions of a rural all-way stop controlled intersection between Victoria Avenue and Canborough Road in the Town of Pelham, Ontario. Several measures of effectiveness are used to rank the proposed solutions, including safety, cost, level of service, and environmental impacts. The proposed alternatives are do-nothing, two-way stop controlled (TWSC), signalized intersection, and roundabout. The paper takes a phased approach and evaluates the proposed alternatives for the design years 2031 (Phase I) and 2051 (Phase II). For Phase I, the alternatives are do-nothing and TWSC, while signalized intersection and roundabout were evaluated for Phase II. The best alternative for each phase was then determined using a scoring method that included weighted criteria; each alternative was graded on a scale from 1 to 5. The results show that for Phase I, AWSC scored 3.15, while TWSC scored 1.50. For Phase II, the signalized intersection scored 2.63, while the roundabout scored 3.63. Taking a phased approach to the improvements ensures the optimization of the cost, capacity, and safety variables affecting the intersection.
