Synthesis of Information Related to Highway Practices. Topic 50-03. Use of Weigh-in-Motion Data for Improving Pavement and Bridge Designs, Weight Enforcement, and Freight Logistics

Characterization of vehicle loads are a critical input for the design and management of transportation structures and systems. The advent of automated means to collect weigh-in-motion (WIM) data has provided for site specific, per vehicle data in lieu of presumptions. While state departments of transportation (DOTs) are required to submit WIM data to the Federal Highway Administration as part of their traffic monitoring programs, some agencies are using actual load data as a tool for internal purposes. Applications for the use WIM data include issuing load restrictions for roads or bridges, improved commercial vehicle weight enforcement, traffic management, work zone management, freight logistics, bridge rehabilitation, and pavement design. The objective of this synthesis is to document how and where DOTs are using WIM data. The study will identify the use of WIM data as a tool for a variety of applications; the quality of data needed for different applications; skills and tools needed to employ the use of data; how WIM programs are monitored; and how much they cost. Effective practices and procedures will be identified. Information will be gathered through literature review, a survey of DOTs, and interviews with selected agencies for case examples. Knowledge gaps and research that could address those gaps will be identified.
