Facility:

KASAI multi modal transport station, underground bicycle parking, automated system

General Description:

Kazaicrane3_2
Underground bicycle parking below a Tokyo Metro Station, and bus station in the highly populated area of Kasai in Edogawa ward east Tokyo. Kasai is considered a role model for multi-modal transport stations. Providing room for 9400 bicycles, the facility is considered one of the biggest of its type in Japan.
The space is divided in two areas east and west; there are three types of bicycle storage spaces. 2920 bicycle spaces consist of double deck tier racks. 1590 tier racks are allocated on the west side whilst 1330 on the east side of the facility. 6480 bicycle spaces are divided on 36 underground towers, each tower able to contain 180 bicycles maximum. The towers are allocated 15 on the west side (4290 bicycle spaces) and 21 towers on the east. The east side has more since the west side of Kan-nana street receives cycling flows from north and west sides of Kasai  (the most highly populated).

Each of the towers has a top booth access where users place their bicycles on a rail-platform, insert prepaid AC cards and then the internal system pulls the bicycles inside and places them on available racks inside. The mechanism is basically a cable crane. The racks are laid out on a carousel arrange, very similar to others previously seen in Spain by Biceberg. The whole process of inserting or collecting a bicycle takes 23 seconds.

Kazaidiagram
The 6480 bicycle spaces of the towers are intended for subscribers only being most of them students, and commuters.  A minimum subscription runs for a month. Before the subscription the bicycle has to be inspected since the design and dimensions of the racks, as well as crane holders and other elements within the tower are intended to match those of a standard Japanese bicycle (female frame shopper bicycle + basket, so-called: mama-chari). Thicker tyres of a MTB, thinner tyres of a road bicycles or smaller 20“ tyres of folding bicycles, simply won’t fit. For subscribers who ride these types of bicycles and other users (visitors and non subscribers) there are 2920 spaces of double deck tier racks.

There are also grey areas, or free-standing spaces which are intended to compensate bicycle parking space when either the towers or the tier-racks run out of capacity, they are designed to cope on special events such as cherry blossom viewing or summer fireworks viewing in which masses of people commute through Kasai station. The grey areas are supposed to allocate 600 bicycles more. These can also serve tricycles and recumbent cycles.
