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

Example Embodiment

[0064] Example one

[0065] Such as figure 1 As a schematic flow chart of a method for sensing traffic operating status based on multi-source data fusion, the method for sensing traffic operating status based on multi-source data fusion provided in an embodiment of the present application may include the following steps:

[0066] S101: Acquire mobile traffic data, where the mobile traffic data includes traffic participant status data acquired through a mobile network;

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

[0068] The traffic participants can use GPS, Beidou and other satellite navigation systems, base stations and Wi-Fi and other network positioning systems through mobile terminals, vehicle terminals and other equipment to report their position, movi...

Example Embodiment

[0101] Example two

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

[0103] After obtaining the traffic operation status of the road network, it may further include:

[0104] Publish the traffic operation status of the road network through a data interface or a display device. The traffic operation status can be published on the display device of the user terminal, the large screen of the traffic status on the road, the traffic monitoring equipment of the traffic management 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 solutions:

[0106] 1. Traffic signal optimization can include:

[0107] According...

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...
