UTCS与UTFGS协同优化研究

Study on Cooperative Optimization of UTCS with UTFGS

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.本研究为UTCS与UTFGS协同的最终实现提供理论指导和方法依据.

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