USE OF ENGINEERING PERFORMANCE IN EVALUATING SIZE AND WEIGHT LIMITS
The Transportation Studies Division of the Federal Highway Administration (FHWA) is carrying out a Comprehensive Truck Size and Weight (TS&W) Study and has developed methodologies and tools for evaluating the effects of size and weight policies on vehicle safety, pavements, bridges, roadway geometry, traffic operations, truck costs, logistics, truck travel, mode share, enforcement, environment, energy conservation, permits and pricing mechanisms. Studies of the influence of a range of TS&W policy scenarios on a wide range of productivity, safety, infrastructure, economic, industrial and community outcomes have been carried out. To provide specific input on the implications of certain changes in size and weight limits with respect to heavy vehicle safety performance, Roaduser Research was commissioned to provide a computer-based analysis of vehicle performance under current and potential future size-and-weight scenarios. The engineering performance of current and potential future US heavy vehicle configurations has been quantified using computer simulation models. The following performance attributes were evaluated: steady-state roll stability; rearward amplification; load transfer ratio; friction utilization; low-speed offtracking; high-speed offtracking; and transient high-speed offtracking.
