Customized public transit network optimization method based on intelligent search

Abstract

A customized public transit network optimization method based on intelligent search comprises the following steps: using network terminals to obtain passenger travel demand data, and building a passenger demand database; building an evaluate index mathematics model satisfying customization public transit and constrained conditions; using N stations ranking in the front in terms of passenger travel population as basis, and building the start point of a backup route set of the customization public transit and initialization routes of N backup route sets; using the initialization routes of N backup route sets as the basis, combing with public transit GIS and station passenger demands, and building a backup route set; using a passenger nonstop rate as a fitness function on the basis of the backup route set, and using a heredity algorithm to search the customized public transit network satisfying the customization public transit evaluate index mathematics model. The method can optimize the passenger nonstop rate so as to build the customized public transit network, thus alleviating partial transport problems, and providing conveniences for passengers to travel.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to an intelligent search-based customized bus line network optimization method. Background technique [0002] With the continuous development of China's economy and the intensification of urbanization, the number of motor vehicles in major cities in my country has grown rapidly, while the number of urban roads is limited, and its growth rate is far lower than the growth rate of motor vehicles, resulting in serious traffic congestion. At the same time, with With the increase of urban population, most cities expand outward in the shape of "spreading big cakes", resulting in unreasonable layout of urban functions, overly scattered residential areas and work areas, excessive travel distances for residents, and many transfers and long time by public transportation. , and the irrational layout of the city has triggered a serious urbanization agglomeration effe...

Problems solved by technology

[0003] When urban managers formulate corresponding policies and measures to solve the problem of "urban disease", they first adopt the method of widening roads and building new roads, but limited investment and urban land resources make the growth rate of urban roads far behind the growth rate of traffic demand , the problems of traffic congestion and environmental pollution are still not effectively resolved
