Embodiment Construction

[0016] The present invention will be further described below in conjunction with the drawings.

[0017] Reference figure 1 , A method to measure the degree of unbalanced spatial distribution of traffic flow in a public transit network, including the following steps:

[0018] Step 1: Statistics and collection of actual urban public transportation network data, including latitude and longitude information of bus stops, location and length of bus lines;

[0019] Step 2: Construct a weighted directed spatial network model of the urban public transport system. The nodes of the network model are public transport stations with longitude and latitude information; if two stations are adjacent stations on a public transport route, there will be a gap between the two stations. There is a connecting edge, which reflects the direction of the corresponding bus line, and its weight is the actual length of the bus line between the two stations. figure 1 Represents a weighted directional spatial pu...

Abstract

The invention provides a method for measuring the imbalance degree of spatial distribution of a public transportation network traffic flow. The method comprises the following steps of: 1, calculating and collecting practical urban public transportation network data; 2, constructing a weighted oriented space network model of an urban public transportation system; 3, randomly selecting an edge e of the network, and calculating the betweenness of the edge; 4, traversing the whole network, and calculating the betweenness of each edge; and 5, calculating the Gini coefficient of the network. The method can be used for evaluating and balancing the imbalance degree of the spatial distribution of the public transportation network traffic flow, and is beneficial to well controlling and relieving urban traffic jam for the public transportation.

Description

Technical field [0001] The invention relates to the field of network science and public transportation, in particular to a method for measuring the degree of unbalanced spatial distribution of traffic flow in a public transportation network. Background technique [0002] The urban public transportation network is a typical spatial network. The spatial network is a complex network with spatial attributes. The network is embedded in the space where it is located. Each node and edge has its own spatial (geographic) location. The constraints of spatial location have an important influence on the properties of the network. Due to the diversity of public transportation travel modes, people are often not satisfied with traditional travel modes such as walking, buses, and subways. The addition of public bicycles also provides people with richer choices. Therefore, most of the current research on urban public transport networks is becoming more and more important. More and more attention...
