Summary
This report details the Federal Motor Carrier Safety Administration’s (FMCSA) Automated Commercial Motor Vehicle (CMV) Evaluation (ACE) project, which addressed the challenge of conducting roadside inspections and law enforcement interactions for Automated Driving System (ADS)-equipped CMVs. Current inspection protocols assume the presence of a human driver to interpret signage, respond to police signals, and provide verbal or physical documentation. The study aimed to demonstrate how ADS-equipped vehicles could communicate necessary safety data to inspectors and respond to law enforcement commands via wireless technologies, thereby establishing a foundation for standardized, efficient interactions without human intervention. The research team designed and executed six operational test scenarios using an FMCSA ACE Program vehicle equipped with SAE Level 3 automation capabilities and the open-source CARMA software platform. Testing was conducted on a closed test track to simulate real-world conditions. The vehicle was integrated with additional hardware, including a Tire Pressure Monitoring System (TPMS), Real-Time Kinematic (RTK) GPS corrections, and a mobile weigh station bypass unit provided by PrePass Safety Alliance. The software architecture was enhanced with new plugins to manage ADS health status, populate safety data messages (SDMS), and detect law enforcement vehicles. The scenarios covered electronic confirmation of ADS health, predictive maintenance data transfer, pre-trip inspection certification, weigh station compliance (pull-in or bypass), data population into roadside inspection applications, and responses to emergency vehicle lights. The demonstrations successfully validated that ADS-equipped CMVs can perform required inspections and interactions through wireless communication. The vehicle transmitted an SDMS via cellular and Radio Frequency Identification (RFID) links to a roadside computer and the weigh station bypass provider. This transmission included new data elements regarding ADS health and safety status, which were successfully parsed and displayed on a mock inspection platform. The data exchange between the vehicle, the mobile bypass unit, and the provider server occurred within 2.65 seconds. Furthermore, the vehicle demonstrated compliance with move-over laws by detecting a law enforcement vehicle’s activated light bar and executing appropriate pull-over and move-over maneuvers. The system also successfully communicated pre-trip inspection data and tire pressure information to roadside entities. The findings indicate that procedural, software, and hardware modifications are necessary to integrate ADS-equipped CMVs into existing roadside inspection infrastructure. The project proved that consistent, well-defined communication standards and vehicular performance capabilities are essential for widespread adoption. By demonstrating the feasibility of electronic data transfer and automated response to law enforcement, the study provides critical insights for policymakers, law enforcement, and ADS developers. It highlights the need for standardized safety data message sets to prevent a fragmented landscape of interaction methods, ultimately supporting the safe and efficient integration of automated trucks into commercial transportation networks.
Key finding
Automated driving system-equipped commercial motor vehicles can successfully communicate with roadside inspection systems and comply with law enforcement commands through wireless transmission of safety data messages and sensor-based detection of emergency vehicles.
