The influence of policy on crash rate of long combination vehicles

A comprehensive safety performance study in Alberta Canada has found that Long Combination Vehicles (LCV) operating under special permit have crash rates that are approximately 5 times less than common tractor semi-trailers operating on the same roads. The safety benefit is attributed in large part to the special permit policy governing LCV operations in the province. This paper describes the methodology used in the study including the means by which vehicle distance travelled estimates were conducted for calculating crash rate. It also discusses the collision causal factors, truck at fault analysis and crash rate findings. A brief review of policy elements thought to be key influencing factors for LCV safety performance benefits is also included.
