Title:

Effect of Winter Events on Highway Performance in the Province of Alberta

Abstract:

Using data from weigh-in-motion sensors and regional weather data from Environment Canada, the effect on mean vehicular speed of various winter events was determined at six sites across the Alberta provincial highway system. Reduction in vehicular speed and the duration of the speed reduction (time to recovery) were calculated for five event types and differences noted. The methodology developed shows promise for future development of robust, repeatable and easily understood performance measures that can be used to monitor winter events and to develop future benchmarks.
