Colorado Deploys Self-Driving Crash Trucks To Protect Highway Workers

Colorado unveiled an autonomous crash-protection truck designed to absorb highway work zone collisions, removing human drivers from one of the most dangerous road maintenance roles. The Denver Gazette reports: At a press event in Falcon on Monday, the Colorado Department of Transportation demonstrated an autonomous truck-mounted attenuator -- a driverless crash-protection vehicle designed to absorb impacts in roadside work areas. These trucks are already in the state's fleet, but previously required a worker in the cab, leaving them exposed during crashes. 'These vehicles are designed to get hit so people don't have to,' said Kay Kelly, CDOT's chief of innovative mobility. 'We want to remove the human from that truck whenever possible.'

Colorado pioneered this technology in 2017, becoming the first state to test it. Developed by San Diego-based defense contractor Kratos Defense, the company started on autonomous follower systems in 2012 and installed its initial version in Colorado in 2013, according to Maynard Factor, Kratos' vice president of business development. The system uses sensors, actuators, and video links, allowing the unmanned crash truck to trail directly behind a paint-striping or maintenance vehicle. The lead vehicle records its route and transmits navigation data to the follower. Both are equipped with global positioning system and communication tools, with the lead driver monitoring via video feed.

'It's a convoy system,' Factor said. 'The leader does the work, while the driverless vehicle mirrors its path. This protects the operator with the crash truck instead of sitting inside it.' Sensors detect objects darting into the lane, triggering an automatic stop. Operators can pause or override via a user interface featuring forward-facing cameras on the autonomous truck and rear-facing ones on the work vehicle. The trucks, existing state assets, are driven to sites and then switched to autonomous mode. Outfitting each with the technology costs about $1 million, excluding the base vehicle and crash absorber.
