Embodiment Construction

[0053] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0054] First of all, based on the subway space network, combined with the information of train running timetable, construct the subway space-time expansion network. Methods as below:

[0055] Step 1: Extend the physical station on the time axis. The extension method is: according to the train departure timetable, for all the trains of all lines passing through the physical station, use the expansion node for the arrival time point and departure time point respectively express.

[0056] Step 2: Connect the arrival time point and departure time point of the same train on the same line on the same physical node through a stop arc.

[0057] Step 3: Connect the departure time point and arrival time point of the same train on the same line at adjacent physical stations through train running arcs.

[0058] Step 4: Connect the arrival time points and departure time points...

Abstract

The invention relates to an urban subway dynamic passenger flow distribution method constructed on the basis of a time-space network. Based on a subway passenger flow demand and an aging characteristic of passenger travel cost, urban subway dynamic passenger flow constructed by the passenger travel time-space network is distributed. Based on a subway space network, train running timetable information is combined, subway physical stations are expanded in time and space and a minimum cost route among each station in the time-space network is obtained according to a shortest route search algorithm. According to the dynamic passenger flow distribution method, a user balance principle can be met so that a passenger travel time and space route is closer to an actual one.

Description

technical field [0001] The invention relates to a dynamic passenger flow distribution method for urban subways constructed on the basis of spatio-temporal networks. Background technique [0002] With the gradual expansion of subway networks in some cities in my country, the rapid growth of subway passenger flow and the uncertainty of passenger route selection behavior will put forward higher requirements for the operation and management of urban subways. On the other hand, my country's urban subways will be constructed and operated by different investment entities in a gradual manner. For example, the investor and operator of Beijing Metro Line 4 and Daxing Line is Beijing Jinggang Metro Co., Ltd., while the operator of other lines is Beijing Metro Operation Co., Ltd. This marks that my country's urban subway has entered the "multi-operator, multi- Line" network integrated operation era. [0003] At present, my country's urban subways use the automatic fare collection syste...
