摘要
Considering the range anxiety issue caused by the limited driving range and the scarcity of battery charging stations,the conventional multinomial logit(MNL)model with the overlapping path issue was used in route choice modeling to describe the route choice behavior of travelers effectively.Furthermore,the generalized nested logit-based stochastic user equilibrium(GNL-SUE)model with the constraints of multiple user classes and distance limits was proposed.A mathematical model was developed and solved by the method of successive averages.The mathematical model was proven to be analytically equivalent to the modified GNL-SUE model,and the uniqueness of the solution was also confirmed.The proposed mathematical model was tested and compared with the GNL-SUE model without a distance limit and the MNL-SUE model with a distance limit.Results show that the proposed mathematical model can effectively handle the range anxiety and overlapping path challenges.
为了更好地描述出行者的路径选择行为,路径选择建模过程中考虑了有限的驾驶范围和稀缺的充电站引起的范围焦虑问题,以及传统的多项式Logit模型具有的路径重叠问题.提出了多用户类和距离限制约束的广义巢式Logit随机用户平衡(GNL-SUE)模型,给出了相应的数学模型,并使用相继平均法(MSA)对其求解.证明了该数学模型等价于改进的GNL-SUE模型,以及模型解的唯一性.最后,测试了所提出的数学模型的性能,并将其与不含距离限制约束的GNL-SUE模型和含有距离限制约束的多项式Logit随机用户平衡(MNL-SUE)模型进行比较.结果表明,所提出的数学模型能够解决范围焦虑问题和路径重叠问题.
