Abstract:

This paper proposed a multi-modal dynamic traffic assignment model based on travel behavior analysis to distinguish the transportation network status and to analyze the dynamic evolutionary process with the addition of electric vehicles (EVs). Established several travel behavior models for different travel groups based on a discrete choice theory. Proposed a multi-modal dynamic traffic assignment model and a corresponding algorithm based on the point queuing model, considering some factors like the network capacity, the battery surplus, and the charging-station service-level dynamically with doing a numerical example for verification. The results show that the factors, which impact transportation system significantly, include the EV State of Charge (SOC), the charging service fee, and the EV charging-pile number. The proposed scheme for public charging- facility capacity-allocation reduces the users’ cost by 3.61%, reduces the EV charging pile acquisition cost by 15.86%, reduces the CO2 emission from transportation-system by 0.76%, increases the EV charging station operation income by 14.66%, and increases the level of service by 77.09%.
