城市道路信号交叉口配时系统优化设计

摘要

The design instruction mainly introduces the emulation system of circulating of the signal crosses,including creating the mathematics model according to the character of the crosses,using the coefficient of dispersion emulation means,controlling the emulation steps by the random variants created by the computer,finally outputting all kinds of targets needed,and analyzing the results.%在讨论城市道路交叉口运营特征的数学模型基础上,采用优化算法进行设计配时方案.优化算法以事件步长法推进仿真钟,模拟输出运行延误,通行能力和饱和度等主要评价指标.在对输出结果进行分析后,可以对信号控制交叉口进行通行效率评价.
