Abstract

There are some studies that analyze public transport service gap by region from comparing supply and demand. However, due to data limitations, previous studies were limited in subdividing region-based service gap by Origin-Destination (O-D). This study analyzes the gaps of public transport services based on O-D, a micro spatial unit. The data used in this study include timetable of public transport and smart card data stored with transportation used records of individual users. The supply index presented in this study is based on O-D travel time considering for temporal fluctuation. And the demand index is explained in terms of actual traffic of O-D. The proposed methodology is applied to Seoul metropolitan city and the analysis for identifying service gap is conducted along major time periods of a day. Visualization is performed on some O-D pairs that require improvements in supply relative to demand. The areas where disparities in service exist were identified.
