Abstract

The High-Risk Corridor (HRC) Program of British Columbia, Canada, was created because of recognition that a safe roadway environment is a shared responsibility of several public agencies, including the police and the road authority. In British Columbia, another public agency interested in and responsible for road safety is the Insurance Corporation of British Columbia, a provincial agency responsible for vehicle insurance and driver licensing services. It was felt that coordinated strategic efforts by public agencies responsible for road safety could yield greater safety benefits than individual agency efforts undertaken in isolation. This paper provides an overview of British Columbia's HRC Program and presents a case study example to demonstrate the program's success in reducing frequency and severity of collisions on an HRC. The paper also describes the program's technical elements, including how corridors are defined as high risk and the collision and infrastructure analysis used to guide the interventions deployed as part of the program. Coordinated strategic efforts between agencies are detailed to illustrate the range and integration of road safety initiatives. Finally, results of a robust time series evaluation are presented to show the significant and positive safety impact of the HRC Program, which has resulted in a large reduction in frequency and severity of collisions.
