Using exposure-based evidence to assess regulatory compliance of productivity-permitted long trucks

This paper uses exposure-based evidence to assess regulatory compliance of productivity-permitted long trucks (Rocky Mountain doubles, Turnpike doubles, and triples). Compliance is considered a latent (unobservable) variable and is expressed as a function of exposure and the regulatory environment. This generic expression is applied to long truck operations in the Canadian Prairie Region by using exposure indicators to assess long truck compliance with network restrictions, weight limits, and safety-related operational conditions. The analysis finds that 99 percent of observed long trucks comply with the undivided highway network restriction and prescribed weight limits. Using exposure-based collision rates as a surrogate for assessing safety compliance, published evidence demonstrates that long trucks have a lower collision rate than other articulated trucks.
