| 摘要： | This report describes the modeling, calibration, and validation of a VISSIM traffic-flow simulation of the San Jose, California, downtown network and examines various evacuation scenarios and first-responder routings to assess strategies that would be effective in the event of a no-notice disaster. The modeled network required a large amount of data on network geometry, signal timings, signal coordination schemes, and turning-movement volumes. Turning-movement counts at intersections were used to validate the network with the empirical formula-based measure known as the GEH statistic. Once the base network was tested and validated, various scenarios were modeled to estimate evacuation and emergency vehicle arrival times. Based on these scenarios, a variety of emergency plans for San Jose's downtown traffic circulation were tested and validated. The model could be used to evaluate scenarios in other communities by entering their community-specific data. |
