Embodiment Construction
[0054] In order to make the objects, technical solutions, and advantages of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0055] The application scenario of the embodiment of the present invention will be described before the embodiment of the present invention will be explained in detail.
[0056] The embodiment of the present invention is applied to a scenario that needs to be determined to determine the road condition of the target road, wherein the target section is a road segment connected to the traffic light in the road, such as a road segment of 100 meters or 200 meters of the lamp. Specifically, when the vehicle arrives at the target road, the road condition state of the target road section can be issued to the user according to the traffic condition of the published road, and the travel time is estimated on the target section. Alternatively, it is also possible to s...

The invention discloses a method and a device for determining a road condition state, belonging to the technical field of road traffic. The method includes: acquiring the driving information of multiple first vehicles on the target road section, each first vehicle is a vehicle whose vehicle position is located on the target road section within a preset time period, and the driving information includes driving trajectory and waiting light information; according to the multiple first vehicles The driving information of a vehicle determines the road condition characteristics of the target road section. The road condition characteristics of the target road section include the number of first vehicles in different driving information intervals in at least one time period within the preset duration; The road condition features are input into the road condition recognition model, and the road condition state of the target road section is output. The invention can improve the accuracy and efficiency of determining the road condition state.
Description
Technical field [0001] The present invention relates to the field of road traffic technology, and more particularly to a road condition state determination method and apparatus. Background technique [0002] At present, traffic congestion has become an increasing issue of major cities. In order to facilitate user travel, you can provide users with road condition query functions through navigation software. Through the road condition query, users can query the road conditions of each section, and choose the right road section. Drive. Among them, the road conditions of the road segment typically include congestion, slow, and smooth. In addition, due to traffic lights on most roads in the city, the vehicle is easily influenced by the red green light when driving on the road. Therefore, it is necessary to accurately display the road of the road in front of the road, that is, the goal of connecting with traffic lights in the road. Road condition status of the road segment. [0003] In...
