16. Abstract
The purpose of this Implementation Plan is to recommend strategies to encourage the deployment of roadside technologies to improve truck size and weight enforcement in the United States. The plan includes strategies that State practitioners can use to overcome typical challenges confronting the deployment of virtual weigh stations and other roadside enforcement operations (Section 3.0) and overall program support that FHWA needs to provide to jurisdictions looking to deploy virtual weigh stations and other operations (Section 4.0). The plan is the final deliverable in FHWA’s Truck Size and Weight Enforcement Technology project. The goal of the project was to encourage and facilitate states’ technology deployments as a means to improve the efficiency and effectiveness of roadside enforcement.
The Implementation Plan includes a two-page “Reference Guide to Deploying Roadside Technologies” that summarizes the important steps that can be taken by states in order to incorporate new roadside technologies into their enforcement programs. States are encouraged to tailor or modify the guide to suit their particular circumstances and needs.
