Abstract:This project examined how roadside inspections and other law enforcement interactions could be accomplished on ADS-equipped CMVs. This included research into: a) how automated CMVs can deliver necessary information to inspectors and b) how automated CMVs can recognize and respond to inspection locations and directions. These objectives were accomplished by enhancing existing open-source ADS software and demonstrating these enhancements using an ADS-equipped CMV on a test track. This study explored six operational test scenarios designed to represent significant interactions an ADS-equipped CMV may encounter. These scenarios explored data and messaging requirements, preventative maintenance, pre-trip inspection information, interactions with a weigh station, and interactions with law enforcement. Results suggest roadside inspections and interactions with law enforcement can be accomplished on ADS-equipped CMVs. Wireless transmission of a safety data message was demonstrated in real-world testing via cellular communication to a roadside computer and a weigh station bypass provider. Communication of ADS health and safety status data elements within the safety data message was demonstrated as well. Finally, this project demonstrated the maturity of a newly developed law enforcement vehicle light bar detection software plugin as well as compliance with law enforcement commands (pull over, move over).
