Problems solved by technology
However, dynamic factors such as signal control schemes and traffic flow operation conditions all affect the correlation of intersections. The fixed intersection coordination control grouping scheme obviously cannot meet the response requirements of signal control schemes for real-time traffic operation conditions, and may even seriously affect green traffic. wave control effect
At present, many research results have been accumulated in the field of dynamic sub-area division of arterial lines. The dynamic division of signal control sub-areas is realized based on complex division models or artificial intelligence algorithms with a huge amount of data calculation. This method can be based on real-time traffic demand. Effectively adjust the division of sub-regions, but the real-time performance is not good

Description
technical field [0001] The invention relates to intelligent traffic signal control, in particular to a scheme-selective green wave configuration method and system for trunk lines. Background technique [0002] The green wave coordinated control of trunk lines is a commonly used method of coordinated signal control at intersections, which can effectively reduce the number of vehicle stops, improve the efficiency of traffic operation, and ensure the smooth running of trunk lines to a certain extent. Scholars at home and abroad have also carried out a lot of research in the field of green-wave collaborative control of trunk lines, proposing many control strategies and optimization algorithms, such as maximizing the green-wave bandwidth or minimizing the average delay, number of stops, and fuel consumption. The objective is to build an optimization model to adjust the signal timing parameters. The practical application of these methods and technologies has also achieved good res...
