Problems solved by technology

This method has certain application value, but there is no certain basis for the determination of the transfer time threshold, and there are missed judgments and misjudgments for bus passengers whose card swiping intervals are too long or too short; and only time is considered in the transfer identification This single factor does not consider issues such as transfer distance, and the accuracy of transfer recognition is low

Embodiment 1

[0064] Taking the GPS and bus IC card of public transport vehicles in Foshan as an example, select the bus swiping card record of a certain passenger on March 18, 2014, and adopt the present invention to carry out bus transfer identification for this passenger. The specific process is as follows figure 1 and figure 2 shown, including the following steps:

[0065] Step 1. In the step of data fusion based on vehicle GPS and bus IC card data, there is a certain offset between the GPS system time of Foshan City bus and the time of swiping the card recorded by the bus IC card POS machine, and the time of receiving GPS data lags behind the actual time. For 6 seconds, the GPS data reception is calibrated with reference to the time of the bus IC card, and invalid data is eliminated at the same time to complete the fusion of the four system data, as shown in Table 1.

Abstract

The invention discloses a bus transfer identification method based on vehicle GPS and bus IC card data, sequentially comprising the steps as follows: carrying out data fusion based on vehicle GPS and bus IC card data; extracting passenger bus travel data; acquiring a shortest path matrix of bus stops; identifying the get-on stop and the get-off stop; judging a transfer behavior based on the card swiping time interval; identifying the transfer behavior based on the walking distance for transfer; identifying the transfer behavior based on a transfer time threshold; and identifying the transfer behavior based on bus arrival time matching. The method of the invention takes comprehensive factors into consideration, is convenient in calculation and actual operation, is high in practicability, can greatly improve the convenience in and accuracy of bus transfer identification, and has a broad application prospect.

Description

technical field [0001] The invention relates to the field of bus information data processing, in particular to a bus transfer recognition method based on vehicle GPS and bus IC card data. Background technique [0002] As the important passenger flow information of urban residents' bus travel, bus transfer data is of great significance to the planning and management of urban public transport. By analyzing the bus transfer data, it can provide a basis for the site selection and design of transfer hubs. A reasonable urban bus The transfer system can reduce the travel time of urban residents, rationally organize the coordinated development of various public transport modes, improve the operating efficiency of the public transport system, and promote the sustainable development of urban traffic. Therefore, obtaining urban bus transfer data has become one of the important tasks of public transport surveys. [0003] At present, the method of manual investigation is mainly used in C...
