Network Screening for Safety Priorities

Network Screening is increasingly being used by road authorities as a tool to assist in their planning of investments in road improvements. Network screening can be defined as the process of measuring safety within a road network, with the objective of targeting road improvements to achieve the maximum cost-benefit. In British Columbia, the Insurance Corporation of British Columbia (ICBC) has been conducting network screening to prioritize locations for road safety improvements since the early 1990’s. Through its Road Improvement Program, ICBC partners with municipalities to identify and cost-share in upgrades to intersections and corridors. Results have shown significant savings in insurance claims and societal costs and returns on investment, through reduced injury and property damage collisions. In Alberta, the Alberta Motor Association has played a key role in assisting municipalities to identify improvements that can reduce insurance and societal costs associated with collisions, and several municipalities have subsequently set up their own network screening programs. Opus Hamilton has developed methodologies for and conducted numerous network screening exercises on behalf of several road agencies in both British Columbia and Alberta. The key methodologies of network screening are data review, nomination of locations and engineering correctability analysis. This paper will briefly describe these methodologies, provide examples of cost effective safety countermeasures, and report on how network screening has assisted in the decision-making for road improvements and ultimately in the responsible management of the road asset.
