Embodiment 1

[0053] An embodiment of the present invention provides a method for converting traffic information between maps of different granularities, including the following steps:

[0054] Obtain the set of road segments in the processing road network corresponding to the road segments in the published road network;

[0055] Count the coverage mileage ratio of each road condition in the set of road sections;

[0056] According to the proportion of mileage covered by different road conditions, the corresponding road conditions are selected as the road conditions of the road sections in the published road network to complete the conversion of traffic information between maps of different granularities.

[0057] Such as figure 2 As shown, the traffic information conversion method between different granularity maps provided by the embodiment of the present invention includes the following steps:

[0058] S001. Select a road segment L in the published road network.

[0059] S002, accord...

Abstract

The invention discloses a method for traffic information transfer among maps of different granularities and belongs to the field of intelligent traffic. The method comprises the steps that a road section set in a processed road network corresponding to road sections in an issued road network is obtained; a covering mileage ratio of each road condition in the road section set is counted; road conditions of the road sections in the issued road network are determined according to the covering mileage ratios of different road conditions, so that traffic information transfer among the maps of the different granularities is accomplished. The simple, efficient and accurate method for traffic information transfer is provided for the issued road network of the city road conditions, the accuracy of traffic information is improved, and the conditions that a transfer result shows that the road sections are jammed and the transfer result deviates from original road conditions are avoided.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for converting traffic information between maps of different granularities. Background technique [0002] In modern urban life, real-time and dynamic traffic information services are needed by the whole society. It provides efficient and feasible traffic guidance and travel planning information for public travel, transportation, etc., so as to save time, reduce costs and low carbon Environmental protection and other purposes. At present, the traffic information service in the city has become increasingly in-depth and affects people's travel life. [0003] Floating car (Floating Car Data) technology is one of the technical means to obtain road traffic information in modern intelligent transportation systems. It uses positioning technology, wireless communication technology and information processing technology to realize the real-time collection of traffic para...
