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...
