Witkar

The Witkar (Dutch, literally "white car" or "white cart") was one of the first technology-based carsharing projects in the world. It is the invention of Dutch social inventor and politician Luud Schimmelpennink, an industrial designer and at the time Amsterdam city councillor. The project was opened by minister Irene Vorrink on 21 March 1974.

The first actual Witkar project took place in Amsterdam between 1974 and 1986. While it provided daily service for more than 4,000 registered users over those years, the project never got beyond the limited demonstration phase due to a lack of support by government.

The system was initially conceived in 1969 by Schimmelpennink in order to reduce traffic in central Amsterdam, but it failed to win the support of the City Council and was spun off to be developed by a specially formed co-operative society. The co-operative managed to raise loans of US$ 250,000 for the first phase though 1974. This included the design and construction of the vehicles, the purchase of a PDP-11 mini-computer for the central control system, development of the control software, and construction of the first 35 cars and five stations. A further 10 stations were scheduled for operation by the end of 1976, by which time the fleet was to have been extended to 100 vehicles. The ultimate target was 150 stations and 1,000 vehicles, but as a result of lack of government support this never happened.
