信号控制交叉口配时优化研究

Research into Signal Control Cross Distributed Phase Time Optimi zation

针对我国城市交通的固有特色,研究了在不同配时方案条件下,直行与转向车流的延误计算方法。在现有定性化信号相位设计基本原则的基础上,深入研究了混合通行情况下的相位方案设计,提出了多相位控制适用的定量条件。结合传统的经验公式,经过深化与标定,提出了信号配时的优化方法。

This paper analyses the calculational methods of delay time in different distributed time projects combined with our urban traffic characteristics. On the basis of principles for current qualitative signal phase design, through deep study of signal phase and phase order, the quantitative conditions of application of over-two signal phase is put forward. Based on the traditional formula, by deepening and demarcating, this paper puts forward the optimized method of distributed phase time.
