Changwon's aim was to introduce a user-friendly bicycle system that would become part of the city's urban landscape. The city has managed to create a bicycle system matching its own particular needs by researching other cities' bicycle programs, analysing Changwon's physical conditions and by applying advanced technologies. The new system, NUBIJA, has lead to improvements in citizens' health, job creation and has also laid the foundation for a low-carbon transportation culture. The extensive use of information technology and implementation of a cyclist's insurance system are among NUBIJA's unique characteristics.
