Engineering Treatments to Reduce Red-Light Violations

TxDOT Report 0-4196-3: Red-Light-Running Handbook: An Engineer’s Guide to Reducing Red-Light-Related Crashes. J. Bonneson and K. Zimmerman. The objective of this handbook is to describe guidelines for identifying and treating locations that have an unusually large number of red-light violations or related crashes. Separate guidelines are presented for the treatment of red-light problems at individual intersections and within entire cities. The guidelines address countermeasures in both the engineering and the enforcement categories. A spreadsheet was developed to implement the guidelines.  REPORT   SPREADSHEET

TxDOT Report 0-4196-2: Development of Guidelines for Identifying and Treating Locations with a Red-Light-Running Problem. J. Bonneson and K. Zimmerman.. 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. 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 models were also used to quantify the effectiveness of officer enforcement. Procedures were developed to identify and rank problem locations.   REPORT

TxDOT Report 0-4196-1: Review and Evaluation of Enforcement Issues and Safety Statistics Related to Red-Light-Running. J. Bonneson, K. Zimmerman, and Cesar Quiroga. This report describes: (1) the findings from a review of enforcement issues related to red-light violations, (2) the findings from an evaluation the characteristics of red-light-related crashes in Texas, and (3) a procedure for identifying and quantifying red-light-running-related crashes.  REPORT

TxDOT Report 0-4027-2: Engineering Countermeasures to Reduce Red-Light-Running. J. Bonneson, K. Zimmerman, and M. Brewer. This report describes the evaluation of several engineering countermeasures to red-light-running as well as guidelines for selecting appropriate countermeasures and evaluating their performance.  REPORT
