Abstract

The invention provides a topology modeling method and system of a traffic road network. The method includes: obtaining road information of all roads in the target traffic road network, using the road information to form a key element information library; Organize the road information in the information database, create intersection information and road section information; use the intersection information, road section information and recursive algorithm to establish the topology model of the target traffic road network. The present invention encodes and arranges the road information of all roads in the target traffic road network to create intersection information and road section information. The topology model of the target traffic road network, the encoding model can support eight-way intersections, which can meet the modeling requirements of urban complex road conditions, reduce manual operations, reduce the error rate of road network information matching, and improve the convenience and accuracy of the system and operability.

Description

technical field [0001] The invention relates to the technical field of urban traffic digitization, in particular to a topology modeling method and system of a traffic road network. Background technique [0002] With the rapid development of modern science and technology, traffic organization management is also moving towards digitization, informationization and scientificization. Road network topology modeling based on GIS maps is a key part of realizing traffic information management and control, and lays a solid foundation for comprehensive traffic perception, discovery, reproduction, and optimization based on road networks. According to the graphic characteristics of the network, the urban road network can be divided into the following categories: square type, belt type, radial type, radial ring type, free type, and mixed type. In real life, affected by urban planning, topography, historical conditions, etc., there are often many irregular and complex intersections in th...
