Analysis Of The Influence Of Range Anxiety Of Electric Vehicle Users On Hybrid Network Equilibrium

The Electric Vehicles(EVs)play a positive role in the development of renewable energy.Meanwhile,the multi-dimensional policy and mechanism promotes the development of the EVs.The EVs have gradually become the main participants in the urban transportation.However,poor battery condition,external environment,driving conditions,and other factors will induce the difference between the actual remaining power and the expected remaining power.Drivers will appear range anxiety when driving EVs.Therefore,the impact of range anxiety on traffic congestion and safety can provide a reference for the formulation of traffic regulations and policies under the hybridization of EVs.This paper investigates the safety buffer value required by EV users in different scenarios and driving behaviors under the stress of range anxiety through the Stated Preference.Respondents will be asked to answer the remaining mileage corresponding to the minimum remaining power they could accept when the actual travel trip is 10 km,30 km and 60 km.The driving behaviors that drivers will choose when they face range anxiety also need to be answered.In addition,the respondents’ satisfaction with their vehicles and driving style will also be evaluated.The survey results showed that the safety buffer value varies with the trip mileage.And drivers expect the mileage of the vehicle to be greater than the actual mileage to ensure the comfort and safety of travel.The driving behaviors under range anxiety are to extend the remaining driving mileage of the vehicle.Then,based on the conclusions drawn from the SP survey,this paper classifies the users in the traffic network,expounds the differences in the travel time and driving behavior of different types of users.By processing related factor and variables to improve the accuracy and validity of the model,this paper constructs a mixed traffic equilibrium model that considers driving behavior preference under range anxiety.Taking Changsha-Zhuzhou-Xiangtan regional road network as an example,this paper quantitatively analyze the impact of remaining power on traffic flow distribution,the relationship between range anxiety and remaining power,and the impact of range anxiety on traffic safety or traffic congestion.
