Improving Safety and Efficiency of Signalized Intersections during Inclement Weather

Inclement weather, such as rain, snow, fog, and ice, create special operational challenges for traffic management agencies. This project shall provide Texas Department of Transportation (TxDOT) with technical guidance for improving safety and efficiency of signalized intersections during inclement weather. The Performing Agency shall examine available technologies for detecting adverse weather at signalized intersections and provide technical guidance on strategies for modifying traffic signal operations during various types of weather events. The results of this project will provide a realistic and practical architectural framework for collecting and disseminating weather information to improve signalized intersection operations. As part of this research effort, the Performing Agency shall assess existing TxDOT mechanisms for providing weather responsive traffic signal operations for different types of inclement weather events. Following this assessment, the Performing Agency shall provide TxDOT with practical and implementable guidelines for developing traffic signal liming plans and using specific traffic signal controller features for making significant improvements in safety and congestion at signalized intersection during weather events such as fog, rain, ice, snow, and high winds. The Performing Agency shall provide guidance for operating traffic signals and developing traffic signal timing plans for large scale evacuations, such as hurricane evacuations in coastal regions in the form of revisions to TxDOT Traffic Signal Operations Handbook. A one-day training module for implementing weather responsive traffic operations shall be developed by the Performing Agency and tested as part of this project.
