Abstract： The characteristics of passenger flow is an important indication for public transit network planning and operation optimization. To make up the missing passenger volumes data from the IC card readings, this paper proposes a methodology to estimate the passengers' on-and-off volumes at transit station. The method can effectively solve the problem of time difference between IC card charging system and bus GPS system, and the lagging in the IC card swiping. Taking Tianjin and Shenzhen as example, the paper presents the application of the method from macroscopic to microscopic views, such as bus line investigation and passenger flow characteristics. The integration between bus and rail transit is also discussed. The results show the high accuracy and strong applicability of the methodology in estimating passengers' onand- off volumes at transit station.
