The invention discloses a traffic signal control method based on an edge roadside. The method comprises the following steps: acquiring the traffic flow of each intersection at the current moment; calculating the proportion of the traffic flow of each intersection to the total flow of the intersection to obtain first data; processing the first data through Logistic mapping, and predicting to obtain second data; calculating based on the second data to obtain a Jacobian matrix, and obtaining a Lyapunov index according to the Jacobian matrix; if the Lyapunov index is a positive number, the noise suppression intensity is adjusted based on the Lyapunov index, and a noise suppression factor is obtained; processing the first data based on the noise suppression factor to obtain denoised first data; the denoised first data is processed based on the chaos theory, the signal period and the green light time are dynamically adjusted, and then the pollutant emission amount is calculated; and adjusting the signal period and the green light time again based on the target pollutant discharge amount. According to the invention, the road passing efficiency and the vehicle passing rate are improved, and the parking time and the pollutant discharge amount are reduced.
本发明公开了一种基于边缘路侧的交通信号控制方法,包括:获取当前时刻的交叉口中各路口交通流量;计算各路口交通流量占交叉口总流量的比例,得到第一数据;通过Logistic映射对第一数据进行处理,预测得到第二数据;基于第二数据计算得到雅可比矩阵,并根据雅可比矩阵得到Lyapunov指数;如果Lyapunov指数为正数,则基于Lyapunov指数调整噪声抑制强度,得到噪声抑制因子;基于噪声抑制因子对第一数据进行处理,得到去噪第一数据;基于混沌理论对去噪第一数据处理,动态调整信号周期和绿灯时间,进而计算污染物排放量;基于目标污染物排放量,再次调整信号周期和绿灯时间。本发明提高了道路通行效率和车辆通过率,减少了停车时间和污染物排放量。
