基于互补问题的混合交通信号配时优化模型

根据最优化原理与非线性互补理论,针对混合交通下单点交叉口信号优化配时问题,以延误时间、停车次数和通行能力作为性能指标,研究了城市交通控制的优化模型,提出了与之等价的基于绿灯时间的非线性互补问题,并给出了信号优化配时的牛顿算法.算例表明此方法可行有效,在道路等级相差悬殊及交通量相当的情况下,较蚂蚁算法,总延误有很大的减少;在各进口道饱和度较小的情况下,较仿真结果,性能指标有明显提高.为混合交通下单点交叉口信号优化配时研究提出一种新思路和新方法.

Complementarity problems-based optimization model for the signal timing under mixed traffic conditions

This paper discussed the optimization model of urban traffic control.It took delay time, number of stopping and traffic capacity as the performance indicators for single-point intersection signal timing under mixed traffic conditions.By using the Optimization method and nonlinear complementarity theory,signal timing optimization model was formulated as a nonlinear complementarity problem where the variables are green time of phases at intersections and Newton method for signal optimization timing was presen...
