Abstract:

This research project investigated the application of remote driving technology for Truck Mounted Attenuator (TMA) operations. TMAs are necessary to protect the working crew from errant vehicles in support of various maintenance functions. The problem is that the driver of the TMA is susceptible to injury in high-speed crashes. The motivation is to mitigate injury potential for the driver by removing them from behind the wheel and into a remote driving station. This research study evaluated the existing state of commercially available remote driving technology and through a competitive bidding process acquired a system and tested it through several test scenarios designed in this research to evaluate its applicability for Caltrans TMA operations. The test results provided data indicating that remote driving is a viable option for Caltrans’ TMA trucks in areas where the cellular network has a sound coverage, and the roadway lane width and geometry do not provide very tight and complex driving conditions.
