Evaluation of a Low-Cost Countermeasure to Prevent Incorrect Turns at Highway-Rail Grade Crossings

Vehicle incursion onto rail tracks is a significant safety issue at highway-rail at-grade crossings. Rail track incursion incidents are observed primarily at these crossings adjacent to roadway facilities at which turning movements are expected (i.e., intersections, driveways, ramps, etc.). Figure 1a presents a scenario involving an incorrect turn onto railroad tracks near an on-ramp. Drivers unfamiliar with the area or distracted may enter the turning lane and make a wrong decision at the apparent turning point. Once the driver passes the shoulder and the lateral concrete slab, the vehicle will likely get stuck on the railroad tracks, leading to a hazardous situation.
