ABSTRACT
Previous studies on the planning mode of toll facilities mainly focused on flat cities, but the influence of urban topographic features on planning results was ignored. This work examines the new planning model of fast charging facilities considering the effect of the terrain characteristics of mountainous cities. Firstly, the traffic characteristics of mountainous cities are studied from a relative height, and the travel energy consumption of electric vehicles (EVs) is calculated. Then estimate the charging demand of electric vehicles and allocate them according to traffic flow. Finally, the land purchase coefficient based on the phenomenon of urban function agglomeration in mountainous areas is put forward. This coefficient is included in the formulation of the planning model, with the aim of minimizing the total annual social cost. The proposed planning method is verified by numerical experiments. The experimental results show that the terrain features of mountainous cities increase the energy consumption of electric vehicles and limit their scope, thus changing the planning results. Meanwhile, extended analysis shows that the planning results are also influenced by the value of climbing coefficient and the maximum service duration of charging facilities.
