Millen, GA, is a key hub for truck and rail traffic. Yet three at-grade rail crossings in the city often cause delays due to stopped trains, leading to congestion and driver frustration. To address this issue, The Georgia Department of Transportation installed static signs, flashers, and dynamic message signs using a combination of existing and new passive detection technology – with a video detection platform the most innovative aspect this effort. GDOT engineers collaborated with the vendor to accurately detect trains based on crossing signals. Video analytics processed through a traffic signal controller send alerts to nearby signals and multiple remote Changeable Message Signs via a cellular network. Costing just $130,000, these signs notify drivers of blocked crossings, helping them find alternate routes and reducing delays. Before the signs were installed, drivers relied on navigation apps to find alternate routes, often encountering unexpected blockages. Now, travelers receive real-time alerts seconds before committing to a route through the city. The use of video analytics and cellular communication allowed for non-invasive train detection, keeping the project within GDOT’s right-of-way and reducing both costs and the timeline.
