• Abstract:
  Monitoring truck weights is essential for traffic operations, roadway design, traffic safety, and regulations. ; Traditional roadside static truck weighing stations have many operational shortcomings, and so there have ; been ongoing efforts to develop and implement Weigh-In-Motion (WIM) systems to make vehicle weight ; monitoring and enforcement more automatic, unobtrusive, and cost-effective. Current WIM systems ; typically rely on a transverse, instrumented beam installed in the roadway itself, which then can act as a ; transducer system whose response can be related to vehicle weights via calibration and basic principles. ; These systems work reasonably well, but they are still relatively costly to install and maintain since they ; require nontrivial modification of the roadway itself, and there are limitations on where and when they can ; be installed. The work aims to investigate an approach to WIM systems that can greatly reduce costs ; and increase flexibility and reliability by using the fact that the unmodified roadway pavement/foundation ; subsystem itself can be viewed as a transducer system amenable to direct characterization and calibration. ; Rather than using a relatively expensive, obtrusive single sensor system, the proposed approach would use ; a large number of inexpensive, self-powered, unobtrusive wireless sensor devices that would work ; together at a given location to achieve reasonably accurate vehicle weight measurement without modifying ; the roadway itself. The fundamental technologies and theoretical building blocks underlying the proposed ; approach all exist, but research is needed to answer a number of technical and practical questions to enable ; the development of a deployable system. To this end, we propose the development of both virtual and ; physical prototype systems that we will use to investigate the feasibility, suitability, accuracy, and ; generality of the proposed technology as a future heavy vehicle weight monitoring system.
