Transit OD Generation Based on Information Technology

Due to development in computer and information technology, data access and collection have becoming more and more convenient. In many cities’ transit system, transit vehicle GPS data and passenger IC card data could be provided. This paper focuses on the method that uses the passenger IC card data (only record once per trip) and transit vehicle GPS data to generate the transit OD matrix. After analyzing the characteristic of transit trips, the author gives the definition of continuity for a transit trip. Based on this definition, this paper then presents a search method to generate the transit OD matrix. The validity of this method has been tested in the modeling process for Zhengzhou city’s comprehensive transportation system. At the end, it is hoped that this research may give a useful lesson for other cities’ transportation modeling practice.
