Embodiment 1

[0043] like figure 1 As shown, this embodiment provides a traffic scene digitization method, including the following steps:

[0044] Establish digital documentation of traffic scenarios;

[0045] The digital documents of traffic scenes include standard road feature documents, non-standard road feature documents and traffic participant documents, as well as global data documents;

[0046] The traffic participant file is used to save various data of traffic participants (people / vehicles). The establishment of this file considers pedestrians and vehicles as traffic participants, which are unstable factors of the traffic scene. Both parties are dynamic and contain their own Dynamic factors, by learning the behaviors caused by the dynamic factors of the traffic participants, provide uncertainty support for the subsequent establishment of the dynamic simulation model of the traffic scene, improve the randomness of the digitization of the traffic scene, and the behavior of the traff...

Abstract

The invention belongs to the technical field of digital simulation, and discloses a traffic scene digitization method. The method comprises the following steps: establishing a traffic scene digitization document; updating the traffic scene digital document according to the traffic scene data acquired in real time; and establishing a traffic scene dynamic simulation model based on the traffic scene digital document. The problems that in the prior art, traffic element standards are not uniform, elements without fixed codes cannot be mutually communicated among scenes, simulation model scenes are single, analysis data volume is not enough, and cluster training cannot be achieved and simulation result accuracy is low due to the fact that traffic scene simulation consideration elements are simple are solved.

Description

technical field [0001] The invention belongs to the technical field of digital simulation, and in particular relates to a traffic scene digital method. Background technique [0002] With the development of the city, the number of private cars has continued to increase, but with the increase in the number of vehicles, the consequence is the occurrence of a large number of traffic accidents, which has brought huge hidden dangers to social stability and personal and property safety. Researchers analyze traffic accidents, hoping to find solutions to reduce the incidence of traffic accidents. [0003] With the development of computer technology, the research on the reproduction of new or built roads and traffic scenes in the field of digital simulation has been recognized by researchers and traffic safety research experts. The data is controllable, the simulation reproduction of the traffic scene can be realized, and the traffic accidents in the traffic scene can be analyzed in ...
