Systemic Safety Review Methodologies

In the past few years, the Systemic Road Safety (SRS) process was introduced by the Federal Highway Administration (FHWA) to address some of the limitations of network screening based on the collision history of specific sites in a road network. The SRS process also considers the site's collision risk factors. Risk factors are those characteristics common to locations experiencing specific types of collisions. In this article, two alternative SRS methodologies (i.e., the core and enhanced methodologies) are presented and used in analyses of the road network in York Region, Ontario. Their analysis results are compared, as well as their complementary nature to the results of network screening (based on site-specific collision history).
