Bus line station optimal arrangement method maximizing space-time reachability

Abstract

The invention relates to a bus line station optimal arrangement method maximizing space-time reachability. The method comprises the following steps: determining an arrangement position and a direction of a single bus line, and obtaining a bus line arrangement line; acquiring passenger trip aggregation point data; acquiring city activity facility point data; acquiring walking network data along the bus line, and associating the walking network data with the bus line arrangement line, passenger trip aggregation points and city activity facility points; calculating total trip time from the trip aggregation points to the activity facility points; determining whether a sum of the total trip time and stay activity time is greater than total available time; constructing a bus line station optimal arrangement model; and obtaining a bus line station arrangement scheme maximizing the space-time reachability by use of a genetic algorithm. According to the invention, through introducing the space-time reachability as an object function, an optimal bus line station arrangement scheme is obtained, and the arrangement scheme satisfies the trip purpose demands of travelers and improves the service level of the bus line.

Description

technical field [0001] The invention relates to the field of public transport planning, and more specifically relates to a method for optimally laying out bus line sites to maximize time-space accessibility. Background technique [0002] With the development of my country's economy and the continuous expansion of urban population, residents are facing more and more problems in travel. With the rapid increase in the number of cars, the problem of urban road congestion is becoming more and more serious. In order to alleviate the problem of urban traffic congestion, city managers have proposed development strategies such as "public transportation priority". Public transportation plays an increasingly important role in the travel of urban residents, and the layout of bus stops affects the operational efficiency and service level of public transportation. The increase in the number of stops leads to an increase in travel time, and when the number of stops on a single bus line is...

Problems solved by technology

That is to say, the existing bus line station optimization layout model basically starts from the mobility of residents’ travel, and needs to use OD (Origin-Destination) passenger flow to calculate, and does not take into account the accessibility of residents’ travel This is an important indicator, and it is difficult to obtain OD passenger flow, which requires a large-scale actual traffic survey, and the acquisition accuracy is not too high
