  • Abstract:
    Weigh-In-Motion (WIM) data is used for a variety of roadway design and safety purposes. In compliance with Federal Highway Administration (FHWA) mandates, many states have installed permanent WIM sites to measure vehicle weight. Expanding current site coverage to include more roadways and highways requires significant roadside construction and expensive infrastructure support. Moreover, as the number of commercial trucks increases, the ability to enforce weight regulations is decreasing. The distance between inspections and roadside weigh stations for commercial trucks is often significant. Commercial trucks have been known to avoid weigh stations altogether by using bypass routes. An alternative approach to building additional permanent WIM sites is the development of a portable WIM system that provides necessary time and location flexibility for deployment. In addition to DOTs, law enforcement officials could benefit from mobile WIM stations. This project details the development and road-deployment of a heavy truck-centric portable WIM system. This novel approach is a cost-effective alternative to permanent WIM systems. At merely 10% of permanent site costs, the acquisition and quality of needed data is not compromised. This report documents the comprehensive design and development of the portable WIM site trailer; power system; sensors layout and installation method; WIM controller electronic system configuration and calibration; wireless connectivity; real-time monitoring; and data retrieval. Various WIM electronic controller devices, WIM sensor technologies, and portable sensor layouts were investigated. A number of sensor installation methods were studied. Portable-specific WIM controller calibration factors, settings, and configurations were reached. Site-specific deployment of the portable WIM system, its revised setup, installation steps, and data collection is described herein.
