Embodiment Construction

[0032] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0033]Step 1: Use the clustering algorithm based on the density and relative distance of passenger demand points to cluster passenger demand points, and select the hub center station on the new subway network. The selected nodes should meet the following criteria: (1) The passenger demand at the station is greater than The average site demand (2) is greater than 2km away from other nodes with similar demand density.

[0034] First, the density ρ of each demand node needs to be calculated i and distances to other nodes in, d 0 Indicates the radius of the service area of ​​the transportation hub. and

[0035] The clustering algorithm can be divided into two stages. In Phase 1, the location and number of metro hub central stations are selected. A metro station located in the catchment area at the center of the cluster was selected as the hub center ...

Abstract

The invention discloses a hub-and-spoke network framework-based multi-mode public traffic network design method. In a new metro network system, a city general public traffic network is redesigned by taking a hub-and-spoke network as a framework, and a multi-mode traffic transport system is constructed. The method mainly comprises the steps of (1) clustering demand points of passengers by applying a clustering method, and selecting a hub central station for metro stations and bus stations; (2) based on a new metro network, proposing multi-mode traffic network design, including design of main bus routes by adopting a heuristic route generation method and design of feeder bus routes by applying a traveling salesman problem; and (3) establishing a bilevel programming model problem to describe a decision-making process of departure frequency optimization of the routes, and performing solving by utilizing an artificial bee colony algorithm.

Description

[0001] technology neighborhood [0002] The invention relates to a multi-mode public traffic network design method based on a hub-and-spoke network framework, belonging to the field of urban traffic management and control. Background technique [0003] With the continuous deepening of urbanization and the rapid growth of citizens' travel needs, road congestion, air pollution and traffic accidents have become the main concerns of traffic planning in many large cities in the world. From the perspective of traffic demand management, an effective way to solve these problems is to encourage travelers to shift their travel modes from private cars to public transport. my country's major cities are gradually building a multi-mode public transport system with the subway network as the skeleton and a combination of various public transport methods. However, the new subway lines have a greater impact on the passenger flow distribution of the existing bus network. Therefore, the existin...
