The invention discloses a credible preset road network matching method and device, equipment and a storage medium, and relates to the technical field of traffic data analysis and processing, and the method comprises the steps: carrying out the preprocessing of collected road network data, and constructing a road network topology based on the preprocessed road network data, so as to obtain target road network data supporting the passing of vehicles; beidou positioning data corresponding to the current vehicle and sent by the Beidou terminal are received in real time, and road supplementary data corresponding to a road where the current vehicle is located and collected by roadside equipment are acquired in real time; based on the target road network data, performing road network matching on the Beidou positioning data by using a preset road network matching algorithm to obtain a corresponding road network matching result; and performing credible processing on the road network matching result based on the road supplementary data to obtain a corresponding road network matching credible result. According to the invention, the roadside equipment assists the Beidou terminal in positioning, so that the accuracy of track matching with the road network can be effectively improved.
