The problem of red-light-running is widespread and growing; its cost to society is significant. However, the literature is void of quantitative guidelines that can be used to identify and treat problem locations. Moreover, there has been concern voiced over the validity of various methods used to identify problem locations, especially when automated enforcement is being considered. The objectives of this research project were to: (1) quantify the safety impact of red-light-running at intersections in Texas, and (2) provide guidelines for identifying truly problem intersections and whether enforcement or engineering countermeasures are appropriate. This report documents the work performed and conclusions reached as a result of a two-year research project. During the first year, the researchers determined that about 37,700 red-light-related crashes occur each year in Texas. Of this number, 121 crashes are fatal. These crashes have a societal cost to Texans of about $2.0 billion dollars annually. During the second year, red-light-related crash and violation prediction models were developed. These models were used to quantify the effect of various intersection features on crash and violation frequency. The insights obtained were used to identify effective engineering countermeasures. The models were also used to quantify the effectiveness of officer enforcement. Procedures were developed to identify and rank problem locations. The models and procedures were incorporated in a Red-Light-Running Handbook that is intended to serve as a guide to help engineers reduce red-light-related crashes.
