EFFECT OF LARGE TRUCKS ON TRAFFIC SAFETY AND OPERATIONS. FINAL REPORT

This report presents results, findings, and recommendations concerning the operation of longer combination vehicles (LCVs) in Michigan. Various truck combinations were simulated to operate on roadways and highways that are typical of those in Michigan. Several performance modes (operating situations) were used to evaluate each truck configuration and to analyze the simulation results. Policy decisions are called for in those cases where drawing the border line between acceptable and unacceptable performance levels involves more than considerations of vehicle mechanics and dynamics. Specifically, policy decisions are needed to choose between increased no-pass striping, restricted access of various truck configurations, and acceptable reduced levels of traffic flow on free-access roads. Results are presented, and conclusions are drawn regarding combinations that might be accommodated on the current roadway, combinations that require minimal changes to the infrastructure ("optimal" combinations), and the required changes in roadways to accommodate other combinations. Costs and benefits are also addressed.
