| 摘要： | The Washington State Department of Transportation (WSDOT) operates a central traffic management system (TMS) for both day-to-day surveillance and traveler information. Past efforts developed the ability to create real-time traffic speed information by using virtual sensors that are based on transit vehicle tracking data. This project developed a way to provide real-time congestion information from Seattle area arterials and freeways to the WSDOT TMS by using the Intelligent Transportation System Backbone. This system harvests existing automatic vehicle location (AVL) data from within King County Metro Transit and transports the raw data to the UW, where a series of operations converts the data into roadway speed information. |
