Weather Responsive Traffic Management: Deployment of Real-Time Traffic Estimation and Prediction Systems

Traffic Estimation and Prediction Systems (or TrEPS) are real-time systems that interact continuously with loop detectors, roadside sensors and vehicle probes, and provide real-time estimates of traffic conditions, network flow patterns and routing information. TrEPS can be used by traffic managers and operators for evaluating and implementing transportation advisory, control and treatment strategies, including those that mitigate weather impacts. Since TrEPS are capable of predicting where and when drivers travel on the road network, they enable dynamic control and traffic management systems to anticipate problems before they occur, rather than simply reacting to existing conditions. This paper reviews existing applications of weather-responsive advisory and control strategies and proposes a high level framework of deploying real-time traffic estimation and prediction systems for weather responsive traffic management that recognizes modern technological developments including weather and traffic data sensing/forecasting. Recognizing the deficiency in current practice, we develop traffic estimation and prediction models at the corridor and network levels that account for traffic response to inclement weather with presence of advisory and control strategies and incorporate these models in existing TrEPS.
