TRUCK BEHAVIOUR ON HIGHWAY FACILITIES

The recent availability of weigh-in-motion (WIM) traffic monitoring data is exploited for the purpose of investigating safety-related truck behaviour on highway facilities. This paper briefly describes WIM technology and its capabilities to generate traffic monitoring data which are important for traffic safety analysis. The body of the paper provides examples of data analysis that demonstrate the usefulness of WIM data for investigating safety-related truck behaviour. The examples include determination of truck exposure rates, and evaluation of vehicle speed and headway distributions as a function of truck type and truck load.
