Problems solved by technology

However, manual survey methods have insufficient spatial coverage
The cross-section flow monitoring method mainly monitors the traffic flow of certain sections for state monitoring, and the spatial continuity is low, which will also lead to insufficient spatial coverage

Embodiment approach

[0074] In addition to the above-mentioned monitoring of the traffic state of road nodes by sub-entrance, in the embodiment of the present application, traffic state monitoring of road nodes by sub-turning can also be carried out. The main implementation methods are as follows:

[0075] In order to monitor the traffic status of road nodes by turns, the above step 103 can be implemented as: obtaining the navigation behavior data of each vehicle from the dynamic attribute data of the monitoring area according to the vehicle identification. Wherein, the navigation behavior data refers to the data that can reflect the vehicle navigation behavior, for example, it may include: navigation actions (such as turning left, turning right, or going straight, etc.), yaw behavior, path selection behavior, and so on. These navigation behavior data can reflect the navigation actions of the vehicle to a certain extent. Therefore, the navigation behavior of each vehicle can be predicted accordin...

Abstract

The embodiment of the invention provides a traffic state monitoring method and a computer program product. In the embodiment of the invention, static attribute data of a monitoring area and dynamic attribute data of the monitoring area within monitoring time can be acquired; performing track identification on the dynamic attribute data to determine a navigation track attribute corresponding to the monitoring area; then, traffic state parameters of road nodes in the monitoring area within the monitoring time can be calculated according to the static attribute data and the navigation track attributes; and the traffic state of the road node in the monitoring time can be determined according to the traffic state parameter of the road node in the monitoring time. In the embodiment of the invention, traffic state monitoring of all road nodes in the monitoring area can be realized based on the static attribute data of the monitoring area and the mining result of the navigation trajectory attribute in the monitoring area, and improvement of the space coverage of traffic state monitoring is facilitated.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a traffic state monitoring method and a computer program product. Background technique [0002] With the continuous increase of motor vehicles, the problem of traffic congestion is becoming more and more serious, and the pressure of traffic control work is increasing. The monitoring of traffic status can provide reference for the traffic management department to know the traffic status in time and adopt effective traffic management measures. [0003] In the prior art, manual investigation and section flow monitoring are the main ways of traffic state monitoring. However, the manual survey method has insufficient spatial coverage. The cross-section flow monitoring method mainly monitors the traffic flow of some sections for state monitoring, and the spatial continuity is low, which will also lead to insufficient spatial coverage. Contents of the in...
