为准确刻画交通网络和出行行为的复杂特征,考虑路口的转向延误及路段之间相互作用的非对称性因素,用非线性互补理论建立了带转向延误的非对称用户平衡模型,分析了用户平衡解的存在性.结合列生成算法采用有效路径集来避免枚举路网中所有路径的优点和FBLSA算法求解非线性互补问题的全局收敛性特点,提出了修正FBLSA算法.最后针对一个中等规模的交通网络进行数值实验,结果显示该算法对处理非对称网络是十分有效的.
In order to accurately characterize the complex features of traffic network and travel behavior, the asymmetric user equilibrium model with steering delay is established by considering the steering delay of intersection and the asymmetry of interaction between road segments. The user equilibrium The existence of solutions is solved.According to the characteristics of global convergence of the FBLSA algorithm and the FBLSA algorithm, a modified FBLSA algorithm is proposed by using an efficient path set to avoid the enumeration of all the paths in the road network.Finally, Traffic network numerical experiments, the results show that the algorithm is very effective for dealing with asymmetric networks.
