混合交通条件下的信号交叉口配时设计系统

Signal timing designing system under mixed traffic conditions

根据交叉口信号配时的有关理论,在充分考虑中国城市道路交叉口混合交通流运行特性的基础上,采用V isual Basic程序设计语言开发了适合中国交通实际状况的信号交叉口配时软件系统.经过仿真分析及实际验证表明,利用本系统对信号交叉口进行配时设计,具有计算精度高、计算速度快的优点,并且明显改善了信号交叉口的交通运行状况.

Based on the traffic signal control theory, a signal timing software system is designed using Visual Basic language. The system is suitable to the actual traffic status of China because it takes the traffic flow characteristics at the intersection into account adequately. Simulation analysis and practice validation suggest that using this system for the signal timing design has the priorities of high calculation precision and speed. In addition, the system improves the run conditions of the signalized intersection greatly.
