Seoul Transport Operation and Information Service (TOPIS)

Seoul TOPIS (Transport Operation & Information Service)

Seoul TOPIS refers to the general transport control center responsible for operating and managing Seoul's overall traffic. TOPIS does this by collecting traffic information from the Bus Management System (BMS), the Transport Card System, the unmanned surveillance system and traffic-related authorities and institutions such as Seoul Traffic Broadcasting, Seoul Metropolitan Police Agency and the Korea Expressway Corporation.

The Purpose for Establishing Seoul TOPIS

The system is designed to clear heavy traffic and avoid sudden traffic issues by collecting information on bus operations, the number of people using public transport, traffic density, traffic speeds, incidental situations such as traffic accidents and demonstrations, status of expressways, private traffic information and other information related to transportation, and establishing science-based public transit policies through analysis of this integrated traffic information.
