Problems solved by technology

[0004] The above generated traffic operation status is mainly obtained from the cluster analysis of the data returned by the terminal on the server side. Due to factors such as single data type, errors in terminal device positioning, unstable network transmission data, and the returned data depends on traffic participants, In road sections and time periods with low traffic flow, there is not enough data to be returned. In addition, the returned data lacks an accurate and real-time verification scheme, resulting in the inability to obtain the traffic operation status of some areas and time periods or the obtained traffic operation status is inaccurate , unable to meet the needs of user travel and traffic control and scheduling

Embodiment 1

[0065] Such as figure 1 It is a schematic flowchart of a traffic operation state perception method based on multi-source data fusion. The traffic operation state perception method based on multi-source data fusion provided by the embodiment of the present application may include the following steps:

[0066] S101. Obtain mobile traffic data, where the mobile traffic data includes state data of traffic participants obtained through a mobile network;

[0067] Wherein, the traffic participants include: pedestrians, bicycles, private cars, taxis, online car-hailing, buses, passenger cars, freight vehicles, etc. The position and movement status of these traffic participants in the road network change in real time.

[0068] The traffic participants can report their position, moving speed, moving direction and other states in real time through the mobile Internet through mobile terminals, vehicle terminals and other equipment, using satellite navigation systems such as GPS and Beido...

Embodiment 2

[0102] On the basis of the technical solution based on the fusion of multi-source data to obtain the traffic operation state provided in the first embodiment, this embodiment further provides a scheme for regulating the traffic operation state, as follows:

[0103] After the traffic operation status of the road network is obtained, it may also include:

[0104] Publish the traffic operation status of the road network through the data interface or the display device. The traffic operation status can be published on the display device of the user end, the large screen of the traffic status on the road, the traffic monitoring equipment of the traffic control department, etc., and the navigation route planning service call can also be provided through the data interface.

[0105] This embodiment provides the following three types of traffic operation state control schemes:

[0106] 1. Traffic signal optimization can include:

[0107] According to the traffic operation status of ...

Embodiment 3

[0117] Corresponding to Embodiment 1 and Embodiment 2 of the above method, this embodiment also provides a traffic operation state perception system based on multi-source data fusion, as shown in the schematic diagram of the system architecture shown in 2, the system may include:

[0118] Mobile traffic data acquisition module 201: used to acquire mobile traffic data, the mobile traffic data includes traffic participant status data acquired through the mobile network;

[0119] The first traffic state data acquisition module 202: used to acquire structured first traffic state data from the mobile traffic data; wherein, the first traffic state data may include: first traffic flow data and first traffic event data;

[0120] The fixed traffic data acquiring module 203 is used to acquire the fixed traffic data, the fixed traffic data including the road video data obtained by the camera;

[0121] The second traffic state data acquisition module 204: used to acquire structured secon...

Abstract

The invention discloses a traffic operation state sensing method and system based on multi-source data fusion. The method comprises the following steps: acquiring mobile traffic data; obtaining structured first traffic state data from the mobile traffic data; acquiring fixed traffic data; obtaining structured second traffic state data from the fixed traffic data; fusing the first traffic state data and the second traffic state data to obtain target traffic operation state data; obtaining structured road network data from the map data; and matching the position data of the target traffic operation state data with the position data in the road network data to obtain the traffic operation state of the road network. According to the technical scheme provided by the invention, the comprehensiveand accurate traffic operation state in the road network can be obtained, the traffic control and guidance are facilitated, and the traffic passing efficiency in the road network is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a traffic operation state perception method and system based on multi-source data fusion. Background technique [0002] In the field of transportation, whether it is planning routes during user travel or traffic management not only for traffic control and scheduling, but also increasingly relies on traffic operation status information, such as real-time traffic conditions, traffic events, prohibited and restricted traffic information, etc. When planning routes, users can avoid congested roads and estimated arrival times combined with real-time traffic conditions. Traffic managers can find and locate traffic operation problems according to traffic operation status, and set or adjust traffic signals and road organization in a targeted manner. [0003] At present, one of the most commonly used traffic operation state perception methods in the industry is map and n...
