This study, titled “Methods of Reducing Collisions on Alberta Roads” (MORCOAR), is intended to complement the Alberta Traffic Safety Plan, which includes reducing fatal and serious injury collisions. The primary objective of this project was to develop proven, cost-effective and innovative engineering strategies to cover the range of land use, roadway and speed environments in Alberta. Seven “objective areas” were identified; Speed Related Collisions, Collisions at Unsignalized Intersections, Collisions at Signalized Intersections, Vehicle-Wildlife Collisions, Collisions Along Roadways, Run-Off-Road Collisions, and Collisions Involving Vulnerable Road Users. For each objective area, collision reduction strategies were developed for rural, urban, and suburban situations, for various speed categories. Phase 1 of MORCOAR identified 33 collision reduction measures as Highly Effective Measures, including eight of the most effective (Priority 1). Phase 2 developed application guidance, including the costs, benefits, and suggested 20-year implementation strategy for the 33 Highly Effective Measures, as well as more detailed guidance for the eight Priority 1 measures. A User Guide was also developed to ensure the proper implementation of each measure. The benefits (expected collision reduction ranges for Alberta) and life-cycle costs of each of the Highly Effective Measures were derived, then a range of Benefit Cost Ratio (BCR) values were calculated and compared to produce an implementation strategy. An implementation strategy was developed to facilitate the timely and optimal implementation of the highly effective measures identified in this study. Implementability depends on numerous factors, and was presented for the consideration of each agency and for discussion between agencies. Three time frames were identified at the outset of the study (Immediate, 1-7 years, and 7-20 years).
