The invention discloses a method and a system for calculating the entry time and the transfer time of a subway based on data of a smart card. The method comprises the following steps: S1, preprocessing the data, namely performing quality analysis on the data of the smart card, filtering incomplete and inaccurate data, and matching entry records with exit records of passengers; S2, performing basic data analysis, namely calculating an optimum path between two stations, and calculating shortest time between the two stations; S3, calculating the entry time, namely calculating the entry time from a gate to a station by analyzing a time relationship between the passengers without the transfer of the subway; S4, calculating the transfer time, namely calculating the transfer time among different lines of a transfer station by analyzing a taking time relationship between the passengers needing to transfer the subway and the passengers without the transfer of the subway. The method and the system are low in labor cost and high in extendibility; if new lines or stations are added, only line information needs to be added.
Description
technical field [0001] The invention relates to the fields of spatio-temporal data mining and traffic technology, in particular to a method and system for calculating subway entry time and transfer time based on smart card data. Background technique [0002] Whether analyzing the space-time distribution of subway passengers, simulating the operation of the subway or predicting the density of the subway in real time, two time constants will be used, that is, the walking time from the subway toll gate to the platform under the assumption that the passenger’s walking speed is constant and The time spent walking while changing trains at an interchange station. [0003] At present, there is no method for calculating the entry time and transfer time of subway passengers, but these two times are very important for simulating the operation status of the subway and the spatial and temporal distribution of passengers, such as the known passenger entry time, entry time, The transfer t...
