Abstract

The present invention provides a traffic control method, device, and control equipment. The traffic control method includes: building a traffic model based on digital twin technology; Data synchronization between scenes; performing disturbance control on the real traffic scene to obtain the disturbed traffic data; modifying the model parameters of the traffic model according to the disturbed traffic data to obtain the target traffic model ; using the target traffic model to control a device controller in the real traffic scene, where the device controller is used to control the passage of the target object in the real traffic scene. The method solves the problem that the way of solving the traffic model in the prior art has poor real-time performance and it is difficult to accurately control the traffic.

Description

technical field [0001] The present invention relates to the field of traffic, in particular to a traffic control method, device and control device. Background technique [0002] Since its birth, digital twin technology has attracted a lot of attention, and various industries have gradually begun to apply this technology. [0003] In the transportation industry, traffic digital twin technology has been widely used in traffic status analysis, traffic simulation, etc., but the use of traffic digital twin technology to actively build traffic models has not yet been realized. The so-called active model building refers to the method of perturbing the real-world traffic conditions through the traffic digital twin, then observing the real-world traffic conditions after the disturbance, and then calculating the parameters of the traffic model through data calculation. [0004] In the prior art, most of the information on the road is passively collected by the information collector o...
