The urban bike station is usually an important part of city bike-sharing system. The basic premise of the smart bike-sharing concept is sustainable transportation. Such systems often operate as part of the city’s public transport system. The major issue with the earlier generation of bike station is the waste of public space: Most of recent bike-sharing station occupy a large space which especially precious in city down town area. The ordinary station arrangement of bike always be straight line, this kind of arrangement is unsuitable in urban down town areas specially city public transportation center or business district
As a new solution for city public transportation system, vertically arranged parking/storing spaces for bicycles is attractive. It is also considered to get the bicycles folded and stored more efficiently. The efficient utilization
of three dimensional public spaces must be the critical object of this project.
it is important to integrate bike towers, subway station and bus station together for a higher efficiency.
