A reasonable layout of charging facilities is crucial to electric vehicles(EVs)due to the endurance mileage deficiency. Travel behaviors of EVs are simulated based on the historical trajectories from the automatic number plate recognition(ANPR)data. Thus

by giving an allocation of charging stations

charging behaviors of EVs are simulated using the typical pattern of charging choices based on their trip characteristics. The charging demand and cost of EVs and the profit of operators can be obtained. Consequently

reasonable locations and capacities of charging stations for an optimized layout are determined by minimizing the sum of the charging-trip ratio(CTR)and the cost-benefit ratio(CBR). Furthermore

they should be restricted by user psychology and the capacity of power grid. A case study(including 151 signal intersections)is given to demonstrate the effectiveness of optimization method. Moreover

the influence of workdays/weekends

the increase of traffic demand and the development of battery on the allocation is analyzed.
