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

Characterization of vehicle loads is 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 estimation. 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 a variety of applications and decision making. Uses of WIM data, beyond federal reporting requirements, includes pavement and bridge design and management, load ratings, commercial vehicle weight enforcement screening, and freight planning and logistics. The objective of this synthesis is to document how DOTs use WIM data for asset design, weight enforcement, and freight logistics. The study will identify the use of WIM data as a tool to support decision making. The synthesis is intended to help agencies make more effective use of the WIM data they are collecting. Information to be gathered includes, but is not limited to, how WIM data is incorporated into: Pavement design, Pavement management, Bridge load ratings, Bridge management, Weight enforcement support, and Freight planning and logistics. This synthesis will also document impediments to using WIM data as a tool and will document lessons learned by DOTs. Information will be gathered through literature review, a survey of DOTs, and interviews with selected agencies for case examples. The PI will outline the survey methodology in the work plan. Knowledge gaps and research that could address those gaps will be identified.
