Research on Route Planning of Electric Buses

Abstract

Electric bus has the problems of limited driving distance and long charging time, which cannot fully adapt to the traditional bus lines. In the traditional bus route planning, the optimization of factors such as the number of stations and the location, the frequency of departure, the size of the fleet, and the fare are not considered for the charging waiting time limit. To this end, this paper studies the electric bus route planning, comprehensively considers the design of bus line operation characteristic parameters and the configuration of charging station and charging pile. Constrained by charging waiting time and capacity, a social welfare maximization model is established. According to the number of charging stations, the influence of the configuration of the charging station on one end and both ends of the line is discussed. Based on two different charging strategies, the influence of the charging waiting time on the queue in the charging station is discussed. A heuristic solution algorithm is proposed based on Lagrange method. Numerical examples show that the model can not only realize the design of the number of charging piles and the line operation characteristic parameters that can minimize the social welfare under the constraint of charging waiting time, but also compare and analyze the influence of different charging strategies on the number of charging stations and the configuration of charging piles.
