 Transit-Based Emergency Evacuation with Transit Signal Priority in Sudden-Onset DisasterCiyun Lin and Bowen Gong Discrete Dynamics in Nature and Society, 2016, vol. 2016, 1-13 Abstract: This study presents methods of transit signal priority without transit-only lanes for a transit-based emergency evacuation in a sudden-onset disaster. Arterial priority signal coordination is optimized when a traffic signal control system provides priority signals for transit vehicles along an evacuation route. Transit signal priority is determined by “transit vehicle arrival time estimation,†“queuing vehicle dissipation time estimation,†“traffic signal status estimation,†“transit signal optimization,†and “arterial traffic signal coordination for transit vehicle in evacuation route.†It takes advantage of the large capacities of transit vehicles, reduces the evacuation time, and evacuates as many evacuees as possible. The proposed methods were tested on a simulation platform with Paramics V6.0. To evaluate and compare the performance of transit signal priority, three scenarios were simulated in the simulator. The results indicate that the methods of this study can reduce the travel times of transit vehicles along an evacuation route by 13% and 10%, improve the standard deviation of travel time by 16% and 46%, and decrease the average person delay at a signalized intersection by 22% and 17% when the traffic flow saturation along an evacuation route is and , respectively.
