有流量附加约束动态交通网络平衡的变分不等式表示

Variational Inequality Expression for Dynamic Traffic Network Equilibrium with Path Flow Additional Constraints

为了研究有流量附加约束的动态交通网络平衡问题,将附加约束等价地当作路径的新增阻抗,得到了基于有流量附加约束条件下的Wardrop用户平衡的变分不等式表示,并提供了计算这种平衡配流的另一种方法.该方法由于考虑了路径容量约束,使得这种变分不等式表示更接近现实中有路径流量限制的情形.

This paper examines the problem of dynamic traffic network equilibrium with path flow additional constraints. This is an important part of the advanced transport network researches. We formulate the additional constraints as new adding road costs and present variational inequalities expression for the Wardrop user equilibrium. According to our studies, one can develop a new equilibrium algorithm for the traffic flows. Moreover, the more realistic capacity constraints are considered in the paper.
