Red-Light-Running Collision Avoidance

In this report, the authors present a two step process for developing enhanced signal timing models that may assist in reducing the red light running (RLR) problem. Step one in the process involves the collection of field data with one-second resolution. In order to determine the significant influencing factors of RLR, discrete choice models are estimated. In step two, the TRANSYT-7F software package, along with custom-designed programs, are used for finding the enhanced signal timing plans that have the potential for reducing TLR. Commonly used signal control objectives, such as intersection delay, are maintained at the same time.
