中美交通信号控制器的标准化差异性研究

Standard Differences of Traffic Signal Controller in China and America

为更好地推进我国交通信号控制器的标准化,比较了我国GB25280-2010与美国NEMA TS2中美交通信号控制器在功能、分类、技术要求、参数设置、控制逻辑等方面的差异性,研究了interval、overlap、ring的定义和应用,分析了基于环的控制逻辑方法、优势,对典型交叉口的交通信号相位、灯组及接口端子进行了标准化配置,并对我国基于色步理念的配时体系提出了标准化改进的建议。研究发现采用基于双环8相位的交通信号控制方法,既避免相位冲突,又易形成搭接相位,操作起来标准且简单。

To advance traffic signal controller standardization in China, differences between GB25280-2010 and American NEMA TS2 for traffic signal controller are compared, including function, classification, technical requirements, parameters setting, control logic and other aspects, definition and application of interval, overlap, ring are researched, the advantages and control logic method are analyzed based on ring, standard configuration of phase, traffic signal lights and interface terminals are put forward for a typical intersection. Standard recommendations for improvement are proposed based on color step concept of timing system in China. The study found that using double ring 8 phase traffic signal control method is a good way not only in avoiding conflict, but also easy to form overlap phase and easy to operate.
