基于交通控制与诱导的准动态交通分配策略与算法研究

交通出行诱导系统下的路网动态交通分配是进行交通出行诱导方案分析、评价的基础。本文主要考虑交通控制与诱导信息对路段阻抗的影响和出行者对交通诱导信息的接受程度，给出了两种准动态交通分配的策略：修改了出行路径阻抗和改变了出行路径选择。并基于常规非平衡交通分配，通过OD需求量“全有全无”方法，实现了OD变需求影响下的多时段连续准动态交通分配。最后，通过示例路网，验证了所研究的分配策略与算法的正确性。

Strategies and Algorithm for Quasi-Dynamic Assignment Based on Traffic Control and Guidance

The dynamic traffic assignment of road network with route guidance system is a base for the analysis and evaluation technology of the route guidance system. This paper mainly considered the influence of the traffic control and guidance information on impedance and the acceptance degree of traveler to the traffic guidance information, road and two strategies about the quasi-dynamic traffic assignment： modifying the road impedance and changing the route selection modes, were given. Then, based on the conventional non-equilibrium traffic assignment, the multi-interval quasi-dynamic traffic assignment by the all-or-nothing method under the influence of the changing demand was realized. Finally, the correctness of the assignment strategies and algorithm were verified by a simple example of road network.
