Development of a Real-Time Web-Based Dashboard for Interstate Performance Monitoring

Real-time performance measurement of interstate congestion is critical for successful traffic operations management. Monitoring interstate speeds in real time provides the basis for operations engineers to assess interstate system performance at a high level. Crowdsourced probe vehicle data are real-time speeds on roadways collected from cell phones, GPS devices, and vehicle telematics that can be turned into useful performance measures. This project involved the development of a real-time dashboard to display graphs to characterize the congestion history of interstate roadways using the number of miles operating below 45 mph. The playback feature allows for review of conditions during an event such as a road closure or ice storm.
