Abstract

The invention discloses a bus route network optimization method based on reachability and reachability strength. The method comprises the following steps: obtaining bus route network optimization basic data and serving a bus route network as an initial bus route network; and calculating object function value of the initial bus route network and obtaining an optimal bus route network by utilizing a genetic algorithm. The method can improve bus route network reachability on the service basis of meeting the original travel demands, realizes reachability strength and travel intensity matching maximization, allows the public transport operation cost to be minimum and saves public transport resources.

Description

technical field [0001] The invention belongs to the technical field of public transportation, in particular to a method for optimizing a bus line network based on accessibility and reachability strength. Background technique [0002] With the development of urban economy, the number of urban cars is increasing day by day, increasing urban road traffic congestion. In view of this problem, the key to solving urban traffic congestion is to construct a public transport-oriented urban traffic development road. Public transport travel can not only greatly reduce road vehicles, but also has better economy and environmental protection than car travel. To develop urban public transport, the first thing is to plan the bus line network, and the accessibility of the line network and the matching degree between the accessibility and passenger flow demand are the key to evaluate the bus line network, because on the one hand, the accessibility is directly related to the travel of resident...
