Evaluation of Lighted Pavement Marking Systems with Implementation for Left Turn Lane Entry Restrictions and Lighted Stop Bar Applications

Project Description

The first 7.5 miles of METRORail was constructed to fulfill part of Houston's long range transportation plan. The initial light rail implementation provides for high-capacity transit service in the travel corridor linking the central business district with Midtown, the Museum District, the Texas Medical Center, and the Reliant Park area. In the first six months of revenue operation, METRORail experienced several crashes between motor vehicles and light rail vehicles, with many of the crashes involving left turns by motorists across the track path and failure to stop crashes. As a result, METRO installed lighted in-pavement markers to provide positive guidance to motorists during the times where left turns across the tracks are prohibited and at problematic red-light running locations. The TTI Houston Office is evaluating this federally-approved demonstration project for its impact and effectiveness on operations and crashes at light-rail intersections.
