The transport card can also be substituted with an ordinary bank card or a smart phone. This high-tech pricing system not only eliminates the user’s discomfort of having to queue to recharge the conventional pre-paid transport card, it also facilitates the collection of traffic big data. Considering that 99% of users in Seoul travel with a transport card (Seoul Solution, 2016), the data directly reflect consumer needs and indirectly signal consumer satisfaction. This opens up new opportunities for making transport and land-use decisions more responsive to community needs. Previously, bus stops and subway exits were scattered around the station without proper direction boards, which made transfers inconvenient and time-consuming. Therefore, the city government built a multi-modal transit centre, which brings together 89 bus routes on one spot within a close walking distance to subway lines 1 and 4, as well as KTX express railway (Seoul, 2016b).
