| 摘 要： | 利用投影动态系统理论建立了具有路段通行能力约束的弹性需求交通网络动态演化模型.通过分析节点路段处交通流量与出行阻抗关系,揭示了出行者在网络局部对出行路线进行调整的决策过程,并分别建立了有通行能力约束的路段流量更新方程和弹性交通需求下的节点最短行程时间估计方程.通过在整个网络上整合上述两类方程,得到最终的交通网络投影动态...

| Abstract: | A dynamic traffic network evolutionary model with elastic traffic demands and constraints of link traffic capacity was proposed through using projected dynamical systems theory.Through analyzing the relationship between traffic flow and travel impedance at nodes and on links,the procedure of adjusting travel routes locally on a traffic network was uncovered.At the same time,the equations of link flow updating with traffic capacity constraints and the reiterated estimation equations of the shortest travel ti... |
