可变信号周期的干线公交分段绿波协调控制方法

Methodologies of arterial traffic signal coordinated control for trunk bus segmented progression based on variable cycles

干线交通信号协调控制是针对地面常规公共交通方式信号优先研究的核心内容之一。本文以提高干线公交的服务水平为目标,以干线公交分段绿波周期时变为研究对象,提出了一种可变周期的动态干线公交分段绿波控制算法。本文以一个单点交叉口为样本,比较了实施新技术前后的公交延误情况和社会车辆的延误情况。结合多属性决策理论提出了评估新技术使用效能的方法。通过一个具体算例对新方法进行了验证,验证结果表明本技术具有极好的工程应用前景。

The technology of arterial traffic signal coordinated control is one of the core contents in studying the conventional public transportation over ground with time priority.With the purpose of improving the service level of the trunk bus,an algorithm of the segmented green waves of conventional arterial public transportation,which was inductive and signal period-variable,was proposed.Taking a single intersection as a sample,bus delays before and after the implementation of new technologies with the delays of social vehicles were compared.Combining with the theory of multiple attribute decision making,a method was proposed to evaluate the efficiency of the new technology.A specific example was given to show the effectiveness of the new method.Results showed that the methodology proposed had excellent engineering application prospects.
