Method for obtaining bus stations with bus-waiting and bus-IC-card-holding passengers

Abstract

The invention provides a method for obtaining bus stations with bus-waiting and bus-IC-card-holding passengers, wherein the method comprises simple steps and can accurately obtain the bus stations at which the bus-IC-card-holding passengers get on a bus so as to lay a foundation for summing the number of the passengers getting on the bus and analyzing the distribution of the passengers at each station. The method comprises the following steps: 1) collecting information about the positions of the bus stations along a bus route and storing the information in a geographic information base; 2) receiving bus real-time positioning data, matching the bus real-time positioning data with the information about the positions of the bus stations in the geographic information base so as to obtain bus arrival time data, and storing the bus arrival time data; and 3) reading card slotting records of an IC-card toll collector of the bus, and matching the card slotting times in the card slotting records with bus arrival time, namely corresponding the card slotting record between bus arrival times at two adjacent stations of the same bus with a previous bus station at which the bus-IC-card-holding passengers get on the bus.

Description

technical field [0001] The invention relates to the technical field of traffic data processing, in particular to a method for obtaining boarding stations for passengers with bus IC cards. Background technique [0002] In recent years, with the widespread application of urban bus IC cards, extracting urban bus passenger flow information from IC card information has become another effective method for bus data collection. The IC card contains rich and stable data resources. Through data analysis and processing, real-time and continuous bus passenger flow data can be obtained, which can reflect the distribution of passenger flow to a certain extent, and provide us with a single station and each time period. Spatiotemporal distribution analysis offers the possibility. [0003] However, at present, most urban bus IC cards in China adopt the form that passengers do not distinguish between boarding stations, that is, bus IC cards can only record information such as the passenger's...

Problems solved by technology

The problem with this method is that due to the complexity of the urban driving environment and various random factors that affect the normal implementation of the public transport operation plan, the vehicles usually cannot arrive at the stations along the route according to the planned time. The card swiping site obtained by the time matching result is often wrong

This cluster analysis method has very high requirements for the selection of the time threshold, too large or too small will lead to errors in the judgment of the boarding station

When the value is too large, once the bus travel time between two stations is less than this value, it will be misjudged that the card swiping records of the two stations are of the same type; For a long period of time, the card swiping records of the same site may be misjudged as different types

The selection of time thresholds should be different in different passenger flow distribution periods. During off-peak hours, the passenger flow decreases, and some stations may not have card swiping records, so that it is impossible to accurately determine which stations the card swiping records belong to.

Therefore, this method is too complicated for practical application

[0006] In summary, there is no practical application in the prior art, and a method that can accurately obtain the boarding site of bus IC card holders
