The invention provides an induction signal control intersection traffic signal prediction method, which belongs to the technical field of signal control intersection traffic, and comprises the following three parts: historical data acquisition, Markov transition probability matrix construction and traffic signal prediction. When historical data is collected, road traffic flow data and traffic signal data need to be collected and stored locally. And when the Markov transition probability matrix is constructed, the stored historical data is used for construction. And during traffic signal prediction, the obtained Markov transition probability matrix is combined with current traffic flow data and traffic signal data to complete traffic signal prediction. Compared with an existing traffic signal prediction method, the real-time traffic flow state is considered, so that the prediction precision is high, meanwhile, the calculation process is relatively simple, the calculation efficiency is high, and the method provided by the invention is suitable for traffic signal prediction of most induction signal control intersections.

    本发明提供一种感应信号控制交叉口交通信号预测方法,属于信号控制交叉口交通技术领域,其包括三部分,分别是采集历史数据、构建马尔科夫转移概率矩阵、交通信号预测。在采集历史数据时,需要采集道路交通流数据与交通信号数据,并将它们存储至本地。在构建马尔科夫转移概率矩阵时,用存储的历史数据进行构建。在交通信号预测时,用已经得到的马尔科夫转移概率矩阵,结合当前的交通流数据与交通信号数据,完成交通信号预测。本发明与现有的交通信号预测方法相比,考虑了实时的交通流状态,因此预测精度较高,同时由于计算过程相对简单,因此计算效率较高,本发明提供的方法适用于绝大部分的感应信号控制交叉口交通信号预测。
