| 摘 要： | 为了研究由于交通控制设备资源有限,只有部分节点受到控制时交通流在路网上的分配,讨论了交通分配的一般准则和方法,并通过对出行者在控制节点和未控制节点的路径选择行为的假设,建立了混合交通配流模型。模型的最优状态为,出行者在未控制节点处都是选择从该节点到达终点路段综合费用最小的路段,而在控制节点处完全服从控制策略的引导选择路径。研究表明,当所有节点都被控制时,模型等价于SO模型;当所有节点都不受控制时,模型等价于UE模型。用一个简单的路网进行算例分析,说明了模型的可行性和合理性。

| Abstract: | To study traffic assignment problems when just some nodes on the road network are controlled by traffic control center due to limited traffic control devices,the basic methods and principles of traffic assignment were discussed.Based on the assumptions of travelers' route choice behavior at controlled and uncontrolled nodes,a mixed traffic assignment model was established.The optimal status for the proposed model is that,at uncontrolled nodes,travelers always choose the links with minimum comprehensive link... |
