考虑里程焦虑和用户异质性的电池电动汽车交通网络设计模型

A Transportation Network Design Model for Battery Electric Vehicles Considering Range Anxiety and User Heterogeneity

纯电动汽车(BEV)清洁、节能的特点是实现交通行业零排放最终目标的更好选择。然而,电动汽车续航里程短、充电时间长和充电设施不足严重阻碍了BEV的普及。随着电动汽车产业的不断发展,BEV的交通网络最优规划成为一个极其重要的话题。本文立足于经典的网络均衡(UE)理论,考虑BEV充电时间,驾驶员里程焦虑和用户异质性,建立了交通网络设计模型,并在既定的投资上限下优化车道扩展方案(即网络中扩展车道的数量和位置)和充电站选址方案。为了求解模型,我们设计了一种局部最优算法并在其中嵌入了列生成避免路径枚举。通过算例分析证明了模型的有效性。最后对不同的政府投资规模进行敏感性分析。结果表明,该模型的建立对城市电动汽车网络设计具有借鉴意义,为驾驶者出行路线的选择和政府交通规划管理提供了参考。

The clean and energy-saving features of pure electric vehicles (BEV) are a better choice to achieve the ultimate goal of zero emissions in the transportation industry. However, short electric vehicle ranges, long charging times, and insufficient charging facilities have severely hindered the widespread adoption of BEVs. With the continuous development of the electric vehicle industry, the optimal planning of BEV transportation network has become an extremely important topic. Based on the classic UE theory, considering BEV charging time, driver mileage anxiety and user heterogeneity, this paper establishes a traffic network design model, and optimizes the lane extension scheme (that is, the number and location of the extended lanes in the network) under the established investment upper limit and charging station construction scheme. To solve the model, we design a local optimum solution algorithm and embed column generation avoidance path enumeration in it. The validity of the model is proved by the example analysis. Finally, sensitivity analysis is carried out on different scales of government investment. The results show that the establishment of this model has reference significance for the design of urban electric vehicle network, and provides a reference for the driver’s travel route selection and government traffic planning management.
