Problems solved by technology

During the peak period, passengers often have to wait for at least two trains at the station to get on the train. The extension of waiting time causes inconvenience to passengers and reduces passenger satisfaction in the rail transit system.

Embodiment Construction

[0045] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but is not limited thereto.

[0046] The present invention provides a train diagram optimization method for improving the timeliness of passengers, establishes a mathematical model (that is, the waiting time of all passengers on the whole line with constraints), and adjusts the departure interval and the stop time of each station to reduce the waiting time of passengers.

[0047] In the method of the present invention, according to the operating data of the subway operating company, at first obtain the current timetable of a suburban line, the title of the station is represented by number, as shown in table 1 below.

[0048] Table 1 Current timetable

[0049]

[0050] Assuming that passengers enter the station evenly during the peak period, the passenger entry rate at each station is stable, but the value of each station is different, and th...

Abstract

The invention discloses a train operation diagram optimization method for improving passenger timeliness, and belongs to the technical field of urban rail transit operation diagram optimization. The method steps are as follows: Step 1, calculate the number of people waiting for train i at station n; step 2, determine the number of people on board when train i arrives at station n; step 3, calculate the number of people getting off when train i arrives at station n; step 4, determine train i The number of people boarding when arriving at station n Step 5, calculate the waiting time W of passengers at the station, and obtain the model of the waiting time of all passengers on the whole line with constraints. The method can be used to optimize the train diagram, reduce passenger waiting time, and improve passenger satisfaction.

Description

technical field [0001] The invention relates to a method for optimizing a train diagram for improving passenger timeliness, in particular to a method for optimizing an urban rail transit train diagram for reducing the average waiting time of passengers, and belongs to the technical field of urban rail transit diagram optimization. Background technique [0002] In recent years, with the rapid development of urban rail transit, the issue of passenger satisfaction in rail transit systems has attracted attention. The urban rail transit system has the characteristics of large passenger flow and small departure intervals. Passengers are more sensitive to waiting time. Therefore, an important indicator to measure passenger satisfaction is passenger waiting time. The main way to reduce passenger waiting time is to optimize the train map. [0003] At this stage, the research on the optimization of train diagrams has accumulated in theory to a certain extent. The research on reducing...
