Real-Time Work Zone Speed Management and Advanced Safety Alerts System

Maryland
This project demonstrate utilizing UAS (unmanned aircraft) for work zone safety monitoring and speed management. The system has 4 functions: traffic sensing of lane-by-lane data; hazard identification of high-speed vehicles; proactive dissemination of situation-aware alerts; and dynamic downstream alert verification.

Automated Work Zone Speed Control (AWZSC) Program

Connecticut
The state of Connecticut has witnessed a rise in work zone crashes. In 2021, legislation was passed in Connecticut to allow a Pilot program for speed safety cameras in work zones. The Pilot demonstrated that this technology was highly effective at slowing drivers in work zones and led to the passage of a bill in 2024 that authorized the Connecticut Department of Transportation (CTDOT) to operate these in up to 15 highway work zones at a time on a permanent basis. CTDOT began operation in the 2026 construction season of a permanent Program that deploys specialty equipment to detect speeding vehicles, record data and images of the vehicle license plates, and then issue warnings for first time violations, and subsequent infractions for repeat violations. The Program also developed a robust education campaign to support the roadside enforcement equipment. Some of the approaches include an AWZSC-branded fleet of SUVs for both mobile and stationary units, as well as a comprehensive social media campaign. The campaign stressed that the Program is not a profit-driven initiative but a people-focused initiative because our workers' lives matter as much as our residents' or anyone else's.

Camera and LiDAR-Based Near-Miss Detection for Roadside Responder Safety

Alabama
This study used ASAP truck cameras and LiDAR to analyze roadside near-miss incidents, finding many drivers neither moved over nor slowed down. The real-time detection framework supports Move Over Law enforcement, driver training, and evidence-based responder-safety policy evaluation.
