Embodiment Construction

[0028] In order to make the technical solution of the present invention more clear and understandable, the solution of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0029] figure 1 It is a flow chart of an embodiment of the method for constructing a traffic travel scene according to the present invention, such as figure 1 As shown, the following specific implementation methods are included.

[0030] In 101, real urban road network data is acquired.

[0031] In the scheme of the present invention, the simulation of traffic conditions all uses real urban road network data, including expressways, main roads, entrances and exits, and roads in the community. Traffic signs, traffic lights, traffic restrictions, speed limits, etc., are consistent with the real scene.

[0032] How to obtain real urban road network data is an existing technology.

[0033] In 102, real traffic travel sample data is acquire...

Abstract

The invention discloses a transportation scene construction method, device and equipment and a storage medium. The method comprises the steps that true urban road network data is acquired; true transportation sample data is acquired; a transportation model is determined according to the acquired transportation sample data; and a needed transportation scene is simulated according to the urban road network data and the transportation model. By the application of the scheme, the transportation scene conforming to true conditions can be constructed.

Description

[0001] 【Technical field】 [0002] The invention relates to computer application technology, in particular to a method, device, equipment and storage medium for constructing a traffic travel scene. [0003] 【Background technique】 [0004] Modern cities are developing faster and faster, and the accompanying traffic problems are becoming more and more serious. The population and the number of vehicles are constantly increasing. However, the space and capacity of the city are limited, and it is impossible to build new roads and traffic facilities without an upper limit. Traffic congestion has become a problem. major issues of urban development. [0005] Therefore, it is necessary to consider how to alleviate traffic congestion through other means without building new roads and traffic facilities, that is, it is an inevitable development trend to consider new and potential transportation solutions. [0006] For example, the introduction of unmanned vehicles, but since unmanned vehi...
