Embodiment Construction
[0027] like Figure 1-Figure 6 A scheme-selective dynamic green wave control method for traffic signals based on electric police data is shown, including the following steps:
[0028] Step 1: establish a cloud server, and establish a data acquisition module, a data analysis module, a scheme library generation module, a scheme matching module and a scheme sending module in the cloud server;
[0029] Step 2: The data acquisition module is used to connect with the electric police system through the intermediate library, and periodically extract the passing data of each intersection of Lubo;
[0030] The data collection module extracts the passing data of each turning lane at each intersection of Lubo every 15 minutes, and the passing data includes the license plate number and passing time;
[0031] In the data collection described in this embodiment, each turning lane at the intersection needs to be bound with the corresponding electric police bayonet number, and the binding inf...

The invention discloses an electronic police data-based scheme selection type traffic signal dynamic green wave control method and belongs to the technical field of intelligent transportation. According to the method, a cloud server is established; a data acquisition module, a data analysis module, a scheme library generation module, a scheme matching module and a scheme sending module are established in the cloud server; and the average travel speed of green waves is calculated by utilizing upstream and downstream electronic police data; on the basis of the average travel speed, alternative schemes suitable for the current running state of the green waves are selected from a scheme library through automatic matching; and the dynamic adjustment of phase difference parameters of each intersection is finished. Compared with a traditional fixed green wave or time-division-based green wave control mode, the method has a self-adjusting capacity, can adapt to complex and changeable traffic flows of urban roads, and can achieve mode conversion from manual decision making to intelligent decision making. With the method adopted, existing resources are fully utilized, repeated construction is avoided, and investment cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of intelligent traffic, and in particular relates to a scheme-selective dynamic green wave control method for traffic signals based on electric police data. Background technique [0002] With the rapid economic development, the continuous expansion of the city scale, the continuous growth of car ownership, the traffic problem is becoming more and more serious. Urban road traffic signal control has become an important means to improve urban traffic operation, including induction control, periodic control, green wave control, etc. Due to the good optimization effect, green wave control has become the main traffic signal control method used in many cities, including fixed green wave control and time-based green wave control. The traffic flow is a passive control method that requires manual maintenance and updating on a regular basis. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is ...
