Traffic operation state prediction method, device and system

Abstract

The embodiment of the invention provides a traffic operation state prediction method, device and system. The method comprises the following steps: acquiring multi-source traffic data of a target intersection; and on the basis of the multi-source traffic data, establishing a traffic operation state model to obtain a road traffic state and a vehicle traffic state of the target intersection. According to the traffic operation state prediction method, device and system provided by the embodiment of the invention, the traffic flow characteristics of the three types of traffic data sources are integrated and extracted by adopting a multi-modal data fusion technology, and the road traffic state of the current intersection is obtained. Moreover, edge nodes process floating vehicle track data to obtain time sequence characteristics and state characteristics of motor vehicle track information. According to the embodiment of the invention, the traffic state of the intersection is described from two levels of vehicles and roads, the traffic operation state of the intersection can be accurately and comprehensively predicted, and the safety and efficiency of road traffic are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of intelligent transportation, and in particular to a method and device for predicting traffic operation status. Background technique [0002] With the improvement of people's living standards and the rapid development of cities, the urban transportation system is also facing more and more severe tests with the progress of urban modernization. The number of vehicles increases year by year, vehicle congestion intensifies, traffic accidents occur frequently, and social resources are wasted. The intensification of environmental pollution has seriously affected people's travel efficiency, quality of life, and physical and mental health. Therefore, alleviating traffic congestion in cities has great economic and ecological significance. [0003] The assessment of traffic operation status has a significant impact on the safety and efficiency of road traffic. Monitoring and predicting the traf...
