【摘要】 根据城市交通的特点,提出采用多十字路口统一线控的方法,在基于PC-PLC网络下对干线交通信号进行智能协调控制,有助于主干路方向车流的流动,可有效地减少停车次数和等待时间,提高干线的交通车流量。以实际的城市交通道路为对象进行的计算机仿真结果表明,城市交通干线智能控制方法在提高干线通行能力方面优于单点控制,可为解决城市交通问题提供一种新的途径。更多还原

【Abstract】 According to the characteristics of city transportation, on the PC-PLC network platform, adopting an original uniform line control technology to multi-crossroad, we implement an intelligent and coordinative control to the signals of the city traffic trunk line. This control system effectively reduces the latency time of vehicles and increases the traffic flux of the trunk line. Results of the emulation make clear that this method of intelligent control distinctly overmatches that of one-point control to improve traffic capacity, and consequently provides a novel approach to settle city traffic problem.更多还原
