The micro modeling for electric vehicle and its solution were investigated. A new car-following model for electric vehicle was proposed based on the existing car-following models. The impacts of the electric vehicle's charging electricity were studied from the numerical perspective. The numerical results show that the electric vehicle's charging electricity will destroy the stability of uniform flow and produce some prominent queues and these traffic phenomena are directly related to the initial headway, the distance between two adjacent charging stations and the number of charging stations. The above results can help traffic engineer to choose the position of charging station and the electric vehicle's driver to adjust his/her driving behavior in the traffic system with charging station.
Many car-following models with their own merits have been proposed to explore various traffic problems,but researchers have rarely used vehicle's performance to evaluate them.In this paper,we study each vehicle's fuel consumption of the optimal velocity model,full velocity difference model,full velocity and acceleration difference model and the car-following model with consideration of the traffic interruption probability under two traffic situations,respectively.The numerical results show that the car-following model with consideration of traffic interruption probability can reduce vehicle's fuel consumption in the two studied traffic situations and thus improve the vehicle's fuel economy.
