分别给出了动态交通配流(DTA)理论中与瞬时动态用户最优及理想动态用户最优条件等价的两个不等式问题,其中不等式中采用针对迄节点的路段变量,在符合现实中人们择路行为的同时为用户提供较为全面地诱导信息.在此基础上进一步分析了该不等式作为动态用户最优条件的等价性约束在具体相关交通问题中的应用.将该不等式问题作为等价性约束条件放到实际交通问题的模型当中,为动态交通分配理论的应用研究提供了新方法;该不等式为DUO模型提供了一种计算最小路径阻抗的方法,以及在求解模型时可以将其作为验证模型解是否满足DUO条件的算法收敛准则.
The two inequality problems of dynamic traffic assignment (DTA) theory, which are equivalent to the optimal and ideal dynamic user optimal conditions of instantaneous dynamic users, are respectively given. In the inequality, the link variables for nodes are given, Road behavior and provide more comprehensive information for the user.On the basis of this, we further analyze the application of the inequality as the equivalence constraint of the dynamic user optimal conditions in the specific related traffic problem.With this inequality as the equivalent Constraints are put into the model of practical traffic problem, which provides a new method for the application of dynamic traffic assignment theory. This inequality provides a method for calculating the minimum path impedance for the DUO model and can be used as a verification method in solving the model Algorithm Convergence Criterion for Model Solution to Meet DUO Condition.
