Confronting Amsterdam's Parking Problem

According to Geere, with 200,000 official
bicycle parking spots, the city's supply of spaces falls woefully short of accomodating the 300,000 bikes that can be found in public spaces at any one time.

Engineers at the IBA,
the Amsterdam department of engineering, think they've developed a way to help fill this shortfall with a series of "automatic hangers mounted on the city's roofs." A company called Velominck, which
has been building underground bike parking garages in the city
since 2005, seems to be willing to try them out.

"Here's how it'd work. When you arrive at your destination, you
find a Velominck station and swipe a transport card a little like

one of London's Oyster cards against a terminal so it knows who
you are. A door opens, and you clip your bike into a robotic arm,
which then pulls it up a transparent elevator to the roof. It can
then be safely stored there until the owner returns and swipes the
card again -- which summons the bike down from the rooftop."

With completion of the first autmoated rooftop parking system expected to take five years to complete, "the IBA is working on ways to improve the
efficiency of existing bike storage facilities," in the meantime.
