specific Embodiment approach 1

[0060] Specific implementation mode 1: Combination Figure 1 to Figure 3 To explain this embodiment, the method for dividing the operation period of a bus route based on on-board GPS data described in this embodiment is implemented through the following steps:

[0061] Step 1. Extract bus line operating time division indicators: suppose a bus line sends M buses from the departure station every day, the first bus is numbered 1, and so on, the last bus is numbered M, and the line has N operating hours , The headway of the nth operating period is H n , 1≤n≤N, suppose it belongs to the nth operating period and the number is m n The average line stopping time of the bus for J consecutive days is D(m n ), 1≤m n ≤M, its calculation method is shown in formula (1).

[0062]

[0063] In formula (1), I represents the number of stops of the bus line, J represents the number of days, and d ij (m n ) Represents the mth n The stop time of the bus at the ith stop on the j day, H min Represents th...

specific Embodiment approach 2

[0115] Specific implementation manner two: combination Figure 1 to Figure 3 To explain this embodiment, the sub-module I in step three (11) of the method for dividing the operation period of bus routes based on on-board GPS data in this embodiment is implemented through the following steps:

[0116] Step A (1), calculate the element u min -1 and the absolute value of the difference between the average line stop time of each element in the temporary collection and the average line-to-station travel time are stored in matrix Y respectively 1 The first and second rows of; calculate the element u max +1 and the absolute value of the difference between the average line stop time of each element in the temporary set and the average line travel time between stations are stored in matrix Y respectively 2 The first and second lines of;

[0117] Step A (two), judgment matrix Y 1 , Y 2 Whether the maximum absolute value of the difference between the two division indicators in the max , △E ...

specific Embodiment approach 3

[0127] Specific implementation mode three: combination Figure 1 to Figure 3 To explain this embodiment, the implementation fee is the step three (twelfth) of the method for dividing the operation period of the bus route based on on-board GPS data. The sub-module II is established through the following steps:

[0128] Step B (1), calculate u min -1 and the absolute value of the difference between the average line stop time of each element in the temporary collection and the average line-to-station travel time are stored in matrix Y respectively 1 The first and second lines of;

[0129] Step B (two), judge whether matrix Y 1 The maximum value of the absolute value of the difference between the two division indicators in is less than or equal to △D max , △E max , If yes, go to step B(3), otherwise go to B(4);

[0130] Step B (three), element u min -1 is included in the temporary collection, and proceed to step B (5);

[0131] Step B (4), add 1 to the class numbers of the k+1 to Kth ...

Abstract

A method for dividing bus route operation periods based on vehicle-mounted GPS data, which relates to a method for dividing bus route operation periods, in particular to a method for dividing bus route operation periods based on vehicle-mounted GPS data. The invention aims to solve the problems of difficulty in acquiring technical data and unreasonable division indicators in the existing bus operation period division technology. The specific steps of the present invention are: extracting the division index of bus line operation period; initially dividing the bus line operation period; splitting the bus line operation period; merging the bus line operation period. The invention is used in the field of transportation.

Description

Technical field [0001] The invention relates to a method for dividing the operation period of a bus route, in particular to a method for dividing the operation period of a bus route based on vehicle-mounted GPS data, and belongs to the field of transportation. Background technique [0002] Prioritizing the development of public transportation is an effective way to alleviate traffic congestion and reduce traffic pollution. Scientific bus dispatching helps to improve the punctuality of buses at the stops, reduces the waiting time of passengers and the operating costs of bus companies, and is an important means to increase the attractiveness of bus travel modes. During daily operating hours (for example, from 6:00 to 22:00), the passenger flow of the bus line changes with time, and there are great differences in passenger flow between different periods. In order to improve the operating efficiency of the public transport system, different scheduling schemes (including departure fr...
