| Abstract: | Inclement weather, such as rain, snow, fog, and ice, create special operational challenges for traffic management agencies. This project provided Texas Department of Transportation with technical guidance for improving safety and efficiency of signalized intersections during inclement weather. As part of this project, the research team examined available technologies for detecting adverse weather at signalized intersections and provided technical guidance on strategies for modifying traffic signal operations during various types of weather events. A realistic and practical architectural framework for collecting and disseminating weather information to improve signalized intersection operations was developed by the research team. The research team deployed the architecture at intersections in Dumas, Burleson, and Nassau Bay and conducted simulation and field studies to explore the benefits of providing weather responsive traffic signal operations. The research team also provided guidance for operating traffic signals and various developing traffic signal timing plans for large scale evacuations, such as hurricane evacuations in coastal regions. |
