Mobility management is a global concept of various policies to ensure the efficient sustainable satisfaction of mobility demands. Intermodality including all transport carriers will provide an increased quality of life and added value. Car sharing may effect a new mobility behaviour and support intermodal concepts by providing various vehicles at various traffic and transport roads. Traffic and transport in urban areas are suffering from an increasing mobility demand. Transport carriers operate in isolation and customer needs are not considered. City cars are expected to be part of the solution to weaknesses in present mobility. Smart appears to be an ideal car to be interconnected with road rail and air-bound transportation. Seamless travelling will provide the customer with a new experience in door to door mobility. Owners and users will gain benefits from strong partnerships within the transportation industry.
