TOPIS analyzes big data. Big data collected by TOPIS, greatly consists of transportation card data, data on bus, taxi operation, speed and traffic volume data by road. Transportation card data is generated whenever you get on or off a mode of transport such as a bus or transfer to another one. Approximately 85 million cases of transportation card data are collected every day. Bus and taxi operation data such as GPS information collected by TOPIS reaches 26 million cases per day.
