Abstract
It is feasible to infer passengers’ boarding and alighting station by using IC card data and GPS data. However, in most cases, the data collected has some problems, such as replicated data and missing data because of the drawbacks of transit system and the influence coming from the external environment. Furthermore, data users cannot explain the data reasonably because they do not know how data is collected. This paper, taking Chengdu transit system as an example, focus on the data cleaning method in data preparation phase. It presents some methods of data cleaning about the data quality problems in IC card and GPS data, and then discusses the triggering distance of buses in Chengdu.
