A multi-strategy integrated method, system, and terminal for inferring missing origin and destination points in public transportation trips.

Abstract

This invention discloses a multi-strategy fusion method, system, and terminal for inferring missing origin and destination points in public transportation trips, belonging to the field of public transportation data processing technology. The method includes: acquiring initial traffic data; preprocessing the initial traffic data to obtain standard trip data, which includes complete trip data and missing trip data, wherein the missing trip data consists of trip records with missing boarding and / or alighting stations; sequentially employing multiple inference strategies in descending order of confidence to infer missing stations in the missing trip data, terminating subsequent strategies after any strategy successfully infers the missing stations; and filling in the inferred missing stations into the missing trip data to obtain target traffic data containing complete origin and destination point information. This invention achieves the beneficial effect of high coverage and high accuracy in completing public transportation trip origin and destination points by progressively invoking multiple inference strategies in descending order of confidence.
