典型四相位信号交叉口交通组织优化应用研究

交叉口交通组织优化的核心是对其各类冲突进行有效控制.针对我国典型四相位信号控制交叉口,提出了典型四相位信号交叉口交通组织优化的方法,即以时间优化为主,空间优化为辅,对自行车与行人进行一体化设计,提出了绿灯间隔时间优化模型和相位衔接优化模型.最后选取武汉市友谊大道与园林路信号交叉口进行了实例验证,验证结果表明,该方法经济实用,能有效提高四相位信号交叉口的通行质量和行车安全,为城市交通信号控制技术的研究与开发提供了理论依据.

Study on Optimizing Traffic Operation of Typical Four-phase signal intersection

The core of optimizing traffic organization at signal intersection is that to effectively separate all kinds of traffic conflicts.In view of the typical four-phase signal intersection in China,the method of optimizing traffic organization at typical four-phase signal intersection is proposed that bike is designed for integration with the pedestrian ,and optimizing the green light interval model and end pedestrians phase and bicycle phase ahead of time. Finally,we select Youyi road and Yuanling road intersection to validate the models,and the results show that the models is effective and practical, can improve the quality and driving safety of four-phase signal Intersection.
