New Bear Alert system aims to shield road workers from speeding drivers
A new alert system could help protect road workers from speeding drivers. Researchers at Morgan State University have developed Bear Alert, a multisensory warning tool designed to reduce accidents in work zones. The technology comes after two Maryland road workers were killed in traffic crashes last year. The Bear Alert system uses sirens, wearable vibrating devices, and flashing solar-powered beacons to warn workers of approaching speeding vehicles. It provides about five seconds for crews to move to safety when a car exceeds safe speeds.
During a test on Hillen Road, the system monitored 50,821 vehicles passing a work zone. Of those, 288 were travelling at 45 mph or faster. The data collected will help shape future safety measures and traffic-calming strategies in high-risk areas.
Maryland has seen 6,701 work zone crashes between 2020 and 2024, leading to 2,365 injuries and 50 deaths. Nationally, over 100,000 such crashes occurred in 2023, causing 899 fatalities and an estimated $39 billion in economic losses.
Morgan State University is now working with partner organisations to test Bear Alert in real-world conditions. A provisional patent for the technology is also being pursued. The system aims to improve safety for road workers by giving them critical reaction time. If successful, it could reduce injuries and fatalities in work zones across the US. Further testing will determine its long-term effectiveness.
