Bus running direction judgment method based on transit IC (Integrated Circuit) card data

Abstract

The invention relates to a bus running direction judgment method based on transit IC (Integrated Circuit) card data. The method comprises the following steps of: extracting passenger flow data of bus stops; extracting first bus transaction records per bus one day by calculating a transaction time interval of every two adjacent transaction records in the transit IC data per bus one day; extractingpassenger flow data of bus stops of the first bus; obtaining passenger empirical data of the bus stops through statistics according to a traffic survey result or transit enterprise operation data; carrying out bus travelling operation judgment on the basis of a dynamic time warping method; and calculating the warping distance between the passenger flow of the bus stops of the first bus and the passenger empirical data of the bus stops in the uplink direction and the downlink direction by utilizing the dynamic time warping method, and judging the bus traveling direction. According to the method disclosed by the invention, the problem of making statistics on transit passenger flow in different running directions in a one-ticket system on the basis of transit IC card data is solved, so that the problem of unbalance of passenger flows in the transit line operation is quantized; and the bus running direction judgment method is helpful for transit planning, operation and management departments to master passenger flow space-time change characteristics of transit lines and provides decision basis for optimization, scheduling, operation, and the like of transit lines.

Description

technical field [0001] The invention relates to a method for judging the running direction of a bus vehicle according to the transaction data of a bus IC card, and belongs to the field of bus information data processing. Background technique [0002] The bus IC card data mining charging system provides low-cost mass data for bus travel analysis. However, because the system is designed to facilitate passenger payment and fare settlement, and does not consider the application in the field of transportation, the IC card data lacks some necessary data. travel information. For example, the bus lines in most cities in my country are one-ticket lines (single card swipe), which lacks information on where passengers get off the bus. Therefore, it is not possible to directly obtain the running direction of bus vehicles (shifts) and the travel direction information of passengers from the bus IC card data. , for traffic analysis. [0003] The existing processing methods include: 1) Mat...

Problems solved by technology

[0003] The current existing processing methods include: 1) Match the vehicle number of each shift in the vehicle dispatching information table with the vehicle number in the IC card data to determine the running direction of each shift, but this method relies on electronic Scheduling information table, need to establish a more complex relational database

2) By installing the vehicle-mounted GPS device, the GPS positioning information and the bus IC card are fused to obtain the vehicle running direction, but this method is limited by the coverage of the GPS device of the bus vehicle, and it is prone to data loss at present, so it cannot guarantee the speed of each shift. direction can be obtained
