Abstract

The invention discloses a bus line network optimization method based on accessibility and reachability strength; it comprises the following steps: obtaining the basic data for optimizing the bus line network and using the bus line network as an initial bus line network, and calculating the initial bus line network The objective function value is calculated by genetic algorithm to obtain the optimal bus line network. The invention can improve the accessibility of the line network on the basis of satisfying the original travel demand service, realize the maximum matching between the reachable intensity and the travel intensity, minimize the bus operation cost, and save bus 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...
