摘要
为了合理地进行信号相位的设计,运用图论中的染色理论方法求解了信号相位数目的最优值,另外采用有序样本动态聚类的方法,研究建立信号相位相序的组合优化模型。通过南京市太平北路-珠江路交叉口作为研究实例,计算验证了文中的方法和模型,并就交通流与信号相位相序的关系进行了分析,为信号交叉口的信号设计,特别是信号相位相序优化研究提供了新思路和新方法。
In order to design the signal phases rationally, the ntunber of the phase is solved by the coloring theory, and the method of dynamic ordinal samples cluster algorithm, and the optimization model of phase combination and arrangement was built up.By the case study of Taipinbeilu-Zhujianglu intersection, the methods and the models were verified. The relationship of the traffic flows and the signal phases and the phase sequence were analyzed. The results provided new ideas and methods for the signal design, especially for the study of the phase optimization.
