• Origin-Destination (O/D) is important information in route choices and trip assignments. In this study, methodology of estimating O/D based on cellular base station information is proposed. GPS coordinates and cellular base station coordinates have acquired on taxies in Cheongju. Three weeks' data were collected and used. Scatter diagram and sample correlation coefficients show that there are few significant differences of O/D pattern among weeks. However, there is a difference in O/D pattern between weekday and weekend. Besides, there is a difference between morning peak and evening peak. Two methodologies are proposed to convert cellular base station-based O/D into an administrative district-based O/D - using the distribution pattern ratio of GPS coordinates and using the coverage area ratio of the base stations. The statistical analyses through scatter diagram, MAPE and RMSE show that there is few significant difference of pattern between the estimated BS-based O/D and GPS-based O/D.
