基于Logit分配的交通网络设计模型的改进粒子群算法
Improved PSO Algorithm for Traffic Network Design Model Based on Logit Assignment
【摘要】 基于随机平衡分配模型与由效用理论推导的Logit交通分配模型的等价性,提出了基于Logit分配的交通网络设计模型。模型求解中,上层模型采用改进的自适应变异粒子群算法,而下层问题直接利用Logit模型求解。仿真结果表明该模型与算法是有效的。
【Abstract】 Because of the equivalenc of stochastic equilibrium assignment model and Logit model based on utility theory,a model for traffic network design problem based on Logit assignment is proposed.The upper model is solved by the improved adaptive PSO with mutation operator and lower model by the Logit model.Simulation demonstrates that this model and algorithm are efficient and effective.
