Bus operation period division and one-way point recommendation method based on time aggregation

Abstract

The invention discloses a bus operation period division and one-way point recommendation method based on time aggregation. The method comprises the following steps: 1) preprocessing bus global satellite positioning data, wherein the step comprises bus one-way time extraction, bus global satellite positioning data standardization processing, and line bus one-way time data screening and elimination; 2) preliminarily analyzing operation periods and determining the number n of the periods; and 3) performing analysis through an improved time aggregation algorithm, and recommending one-way time of each operation period according to obtained operation period division, clustering centers, and extreme points and the obtained number of cases. The invention considers that differences of different periods needs to be considered in operation and optimization scheduling, and provides a scientific and discriminative scheme for operation period division and one-way time recommendation.

Description

technical field [0001] The invention relates to a bus operation period division and one-way point recommendation method based on vehicle historical operation data, and belongs to the field of public transport data mining application and service evaluation. Background technique [0002] In recent years, with the implementation of the public transport priority development policy and the construction of public transport cities, public transport facilities have gradually increased and improved, and the coverage of the network has generally increased. It is represented by ordinary buses in ground public transportation. The attractiveness of buses does not depend mainly on providing more connection capacity, but on the service level, and improving the punctuality rate is one way to improve the service level. As the basis of public transport operation, the bus departure timetable not only affects the travel of passengers, but also affects the operating costs of public transport co...

Problems solved by technology

The patent with the application number 201910325267.0 introduces a method for dividing the operating time of urban public transport lines. This invention investigates the arrival and departure times of each bus on bus line A for K consecutive working days, the time when it leaves each stop, and the time at each stop. Based on the operation data of the basic bus line, the actual headway of the bus is counted, the passenger flow of the bus line is counted, the initial scheme set of bus line operation period division is determined, and the optimal bus line operation period division is optimized. The solution realizes the accurate and fast division of operation periods, and solves the problems of rough division, poor precision and slow division speed of existing methods
