Bremen will introduce a car rental system that has improved the German city's traffic conditions as an Urban Best Practices Area case at World Expo 2010.

The city today got permission from the Expo organizer to begin preparations for its UBPA case presentation.

Zhou Hanmin, deputy director general of the Bureau of Shanghai World Expo Coordination, issued a registration license to Dr. Heiner Heseler, Bremen's Economic and Harbor Minister.

The city will build a pavilion in a paper-folding style to present the case themed "From knowledge to innovation: Urban mobility solutions."

The pavilion will have five exhibition areas – City of Nature, Science, Mobility, Culture and Future.
