Problems solved by technology

However, the urban road network is relatively complex and it is difficult to obtain historical traffic data in many areas. Therefore, for those skilled in the art, how to use the real-time and historical traffic data of some traffic intersections or road sections to effectively calculate the remaining historical traffic data in the urban road network The traffic operation status of traffic intersections or road sections of traffic data is a technical problem that needs to be solved urgently

Abstract

The present invention provides a traffic flow prediction method and device. The method comprises a step of determining a vehicle turning probability from each of the starting intersections to a targetintersection according to vehicle driving trajectory data from the starting intersections to the target intersection, wherein the vehicle turning probability is used for indicating a probability thata vehicle travels from a starting intersection to the target intersection, and a step of determining the traffic flow of the target intersection according to the traffic flow of each of the startingintersections and the vehicle turning probability from each of the starting intersections to the target intersection. According to the method of the embodiment of the present invention, the traffic flow of the target intersection is determined according to the traffic flow of other surrounding intersections and the probability of traffic flow from other surrounding intersections to the target intersection, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a traffic flow prediction method and equipment. Background technique [0002] The city's intelligent transportation system is to combine wireless sensor technology, communication technology and information technology to analyze traffic big data, so as to obtain valuable traffic information for the traffic big data platform. Through these valuable traffic information, government departments can not only understand the travel information of residents in the urban road network and provide reasonable travel routes for residents, but also use this information to conduct traffic survey and analysis, so as to formulate a series of traffic policies conveniently and efficiently management of urban traffic. For example: through the analysis of the starting and ending points of vehicles in the city and the traffic capacity of roads, it can help government departments und...
