The Transportation Research Board (TRB) Highway Traffic Monitoring Committee is a standing committee that was originally formed in 1985 as a Weigh-In-Motion Task Force and that developed into an ITS-oriented committee that studies all functions of traffic monitoring programs. In anticipation of the release of a new Transportation Research Circular, the committee surveyed the state of the practice, best practices, current issues, needs, and research gaps for topics covered in the Circular.
