technical field [0001] The invention relates to a green wave traffic evaluation method based on track data, and aims to design a simple and feasible green wave traffic evaluation method to complete the horizontal comparison of different green wave traffic schemes. Background technique [0002] In recent years, with the rapid increase of urban car ownership, the problem of urban traffic congestion has become more and more serious. As a control method to alleviate urban traffic congestion, green wave traffic has been adopted by many cities due to its simple setting and obvious effect, which in turn promotes the Research on green wave transportation. [0003] However, the current research is more focused on the optimization of the green wave traffic control model, and the optimization results are more based on the ideal experimental environment. Because the green wave traffic scheme will have many interference factors in the actual arterial control, resulting in various green w...

[0003] However, the current research is more focused on the optimization of the green wave traffic control model, and the optimization results are more based on the ideal experimental environment. Because the green wave traffic scheme will have many interference factors in the actual arterial control, resulting in various green wave Optimization models often have low robustness, so it is particularly important to construct a scientific green wave traffic evaluation method and system to complete the accurate evaluation of the actual control effect of green wave traffic

[0004] The evaluation objects of the current green wave traffic evaluation method are mostly the main line of the green wave traffic control scheme and the main line without green wave control or different evaluation schemes caused by different parameters under a certain green wave control model, and for different green wave traffic control models The comparative study of different green wave traffic control models is relatively lacking. Firstly, due to the different parameter settings of different green wave traffic models, the conditions of various models are too idealized, and it is difficult to construct an evaluation system and method suitable for different green wave traffic control models. As far as the data required for the evaluation of the green wave traffic control model is concerned, the accuracy of the experimental simulation data evaluation cannot be guaranteed, and the actual evaluation data required for different green wave traffic operations are difficult to obtain
