The invention discloses a
public transport passenger travel portrait
restoration method and device, equipment and a storage medium. The method comprises the following steps: acquiring a first type of data which contains a passenger identifier but lacks a get-off
station, and a second type of data which contains a complete origin and destination but lacks a
persistent identifier; preprocessing and standardizing the two types of data; aiming at the same operating vehicle, identifying an
anchor point pair and calculating a systematic
clock drift distance, and calibrating a
timestamp of the second type of data; and based on an optimal
allocation algorithm, performing spatial-temporal trajectory matching on the two types of data in the same vehicle shift, and generating a fusion
record simultaneously associated with a unique passenger identifier and a complete travel origin-destination. According to the method, the problem that a single
data source cannot give consideration to accurate single trip restoration and long-term passenger tracking is solved, high-precision and long-term traceable passenger
trip chain construction is realized, and a reliable data basis is provided for
public transport fine analysis and operation management.
