Audible Warning System on TMA and Maintenance Trucks

The project aims to increase the safety of truck-mounted attenuators by developing a system that uses automated audible and visual warnings to detect potential collisions and notify drivers. Researchers will optimize the design of audible warning devices based on physical, engineering and human factors to increase performance in complex operating environments. The research will help the Illinois Department of Transportation build and test prototypes in real-world conditions, especially around work zones, helping to reduce collisions, damage to equipment and traffic disruptions.
