| 摘要： | This article describes PeMS, a freeway Performance Evaluation Monitoring System which converts freeway monitoring data into real- time traffic updates that are accessible via a Web portal. Software converts the data from the vehicle detection network into easy-to-read tables and graphs. Maps of an entire freeway system are displayed for a given urban area. A user can see how long each route to a given destination will take by selecting an origin and destination on the map. Currently, PeMS is available only to engineers at the California Department of Transportation and to the research community. However UC Berkeley Professor Pravin Varaiya, developer of PeMS, hopes that his invention will soon be available through Internet service providers and public agency traveler information systems. |
