A Method for Public Transit OD Estimation Using Transit Smart Card Data

Abstract

With the utilization of Intelligent Transportation Systems (ITS) in public transportation (PT), trip data of passengers are recorded continuously by transit agencies. Researchers developed various algorithms to infer the origin and destination (OD) points of the PT users by using their transit smart card data. The origin and destination matrix is a very vital metric that can help the authorities to analyze public transportation. This study suggests a comprehensive method for OD inference of trips taken on public transportation. The OD pairs of the trips that cannot be inferred using chaining trips are found using the trip histories of the passengers. For the trips that have no further information, we used the overall OD distribution of the studied route.
