Strategies for Successful Implementation of Virtual Weigh and Compliance Systems in California

The California Department of Transportation (Caltrans) is developing a virtual weigh and compliance system (VWCS) for better commercial vehicle monitoring and weight enforcement. The objective of this synthesis is to document recent efforts and technologies associated with the automated monitoring and enforcement of commercial vehicles and to present the current state of the practice in dealing with overweight vehicle enforcement using advanced weigh-in-motion (WIM) technologies.
