Urban Mobility Planning in Mega Cities and Regional Cities - Decision Support system using smart card data to assist public transport planning

초록

Seoul has top levels of use frequency and complexity of public transport. In 2004, public transport network of Seoul has been reformed into an integrated distance based fare system by introducing smart cards which passengers tag when boarding and alighting public vehicles. Data collected from readers in every single bus and metro station are valuable for managing and operating public transport as they can illustrate trip chains of passengers. However, these data has not been intensively analyzed due to the huge size and lack of appropriate algorithms to handle. This study indicates the concept and main functions of Travel Record based Integrated Public transport operation System, called TRIPS, which aims to estimate precise passenger demands and to develop an advanced operation plan by analyzing smart card data. This system is able to overcome some of the problems of existing transport planning tools by integrating bus and metro data, estimating the expected results of operation changes and reflecting demands of station pairs in metro operation planning. The TRIPS project is at the system integration stage. Seoul Metropolitan Government is considering to apply TRIPS as a test bed for a decision support system of public transport operation planning and Seoul Metropolitan Rapid Transit Corporation is planning to apply some solutions of TRIPS.
