Abstract

Increasing traffic volumes, arterials and intersections reaching and surpassing capacity operation, and limited rights-of-way are leading more and more cities to consider and build light rail transit (LRT) systems. LRT systems provide an opportunity to move large numbers of people in high-density areas without adding to oversaturated conditions. However, the challenge to traffic engineers remains to provide signal priority to high-occupancy LRT vehicles within the existing signalized arterial system and maintain coordinated signal operations for vehicular traffic. This article discusses a study that focused on predictive operation in the balance between LRT and vehicular traffic.
