Road network and public transport network matching method and system

Abstract

The invention discloses a road network and public transport network matching method and system. The method comprises the following steps: C1) collecting vector data of all roads in a research area; C2) collecting vector data of all public transit networks in the research area; C3) calculating the direction angle of the road section; C4) establishing association between the bus route and the road section; C5)-C7) matching the bus lines and the road sections to which the intersected bus segments belong; and C8) determining road sections passed by the bus lines and bus lines passing on the road sections, and forming a path road section set of the bus lines and a bus line set of the road sections. For a 'large-block' road network with a large road network distance, a buffer area is created at the midpoint of the road section and is associated with the bus route, so that rapid and accurate matching of the bus route and the passing road section is realized, and for a 'small-block' dense road network, relation analysis of the bus route and the road section at the intersection is increased, and accurate matching is realized.

Description

technical field [0001] The invention relates to the field of computer technology and urban public transportation technology, and specifically refers to a method and system for matching a road network and a bus network. Background technique [0002] With the rapid development of the economy and the continuous expansion of the city, traffic travel has become an important factor affecting urban development and residents' daily life. In order to meet the growing traffic travel needs of residents, my country has proposed a development strategy that prioritizes public transport. Under this background, it is very important to rationally plan, dynamically evaluate, and optimize the urban public transport network. Urban public transport, especially regular public transport, relies on urban roads. Therefore, in the process of urban public transport planning, evaluation, and optimization and adjustment, it is of great significance to determine the road sections that each bus line passe...
