Abstract: Cooperative optimization of UTCS with UTFGS is studied based on subsystem function independence, integration and mutuality. An optimal model based on hierarchical cooperative optimization is established. In the process of solving the model, one guidance cycle consists two close control cycles, using the second control cycle parameters to calculate the next guidance cycle parameters, this calculating method can ensure UTCS and UTFGS follow the real-time traffic flow dynamically. It also ensures UTFGS strategy continuity and dynamic cooperation of UTCS with UTFGS. The simulation result proved that the model in this paper is practical and the algorithm is feasible. The study provides theory and method guide for real cooperation of UTCS with UTFGS application system development.

摘要： 本文根据UTCS与UTFGS子系统功能独立及功能整合和互补的特征，基于递阶优化思想对UTCS与UTFGS进行协同优化建模，在模型求解过程中，本文提出以相邻两个控制周期作为一个诱导周期，利用后一个控制周期的控制参数作为计算下一个诱导周期诱导策略的输入参数，进行跟进计算，这种计算思路既能保证交通控制与诱导和实时交通流的紧密相随和动态性，又能保证诱导策略的连续性和继起性，实现了交通控制与诱导的动态协同。并通过仿真分析说明算法的有效性。本文研究为UTCS与UTFGS协同的最终实现提供理论指导和方法依据。
