Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, the present invention has designed a kind of bus-subway coupling network construction method based on space network, in the actual application process, specifically comprises the following steps:

[0028] Step A. According to the various bus lines in the city, use the Space L traffic network modeling method to construct a weighted undirected bus network. Among them, the same two bus stops on each bus line are used as a bus stop; each bus stop is used as each network Nodes, the network nodes corresponding to the adjacent bus stations on the same bus line are connected, and the weight of the connected edge is the bus line passing through the two bus stations corresponding to the two network nodes. The shortest travel time between stations; the specific example is Figure 2-a As shown, a ...

Abstract

The present invention relates to a method for constructing a bus-metro coupling network based on a space network. The method is characterized in that: a bus network and a metro network are connected by introducing a pedestrian way, the difference between the essence of the two kinds of transport carriers and difference of passengers flow rate caused by the habit of passengers who choose the transport carrier are taken into account; for the time-consuming issue most stressed by people to travel, the time spent on the car, walking time and transfer waiting time are included in the total time spent on the road to carry out the topology of a bus-metro coupling network based on the space network which is more in line with the actual situation; and in addition, a multi-layer network analysis method is also used to calculate the average path length and the average weighted path length of the network. The results show that the constructed network structure performance is better than the previous topology, so that compared with the previous modeling of single-layer and composite networks, the modeling manner of the method disclosed by the present invention can better reflect the real traffic system.

Description

technical field [0001] The invention relates to a method for constructing a bus-subway coupling network based on a space network, and belongs to the technical fields of network science and urban public transportation. Background technique [0002] Urban public transport systems are usually large-scale systems that are integrated with networks of multiple travel modes. Only when these networks (such as rail network and bus network) are well connected can the role of urban transportation system be brought into full play. Due to its large capacity and fast speed, rail transit has become the preferred travel method for most travelers; due to its small number of stations, most travelers prefer to travel by bus and subway. In view of the essential differences between buses and subways, researchers have empirically analyzed the complexity of multi-modal transportation networks, but most of the research is to use the synergy between modes to couple this spatial network into a singl...
