感应控制是城市交通信号控制的重要方法之一,特别适合于交通流量不大但随机波动较大的交叉口的信号控制。本文针对经典的感应控制所存在的效率不高等局限性,研究了感应控制的主要控制参数,给出了配时的推荐计算方法,分析了相序对感应控制的控制效果的影响,提出了一种变相序的多相位感应控制算法。本文所提算法在仿真平台进行了实验,实验结果证明比经典的感应控制方法所产生的车辆的平均延误要低,同时,算法简单易行,实用性较强。
Induction control is one of the important methods of urban traffic signal control. It is especially suitable for signal control of intersections with small traffic flow but large random fluctuations. Aiming at the low efficiency of classical inductive control, this paper studies the main control parameters of inductive control, gives the recommended calculation method of time distribution, analyzes the influence of phase sequence on the control effect of inductive control, Multiphase Sensing Control Algorithm for Displacement Sequence. The proposed algorithm is tested on the simulation platform. The experimental results show that the average delay of vehicles is lower than that of the classical induction control method. At the same time, the algorithm is simple and practical.
