In April 2011 the International Union of Public Transport published a position paper challenging its 3,000-plus member authorities in 92 countries, to become “real mobility providers,” and promoting the joint mobility of public transport in combination with other modes like cycling, car-sharing and taxis.

The paper states that "successful cities rely on effective public transport in synergy with combined mobility services" and encourages its members to build intermodal strategic alliances with Combined Mobility services such as taxis, bikes and car-sharing.
The common and undeniable target is to change citizens’ travel behaviour and offer a genuine alternative to the car.
Modern mobility is based on flexibility and a high level of convenience. Combined Mobility is the answer: carsharing, taxis and shared taxis, bicycle and bike-sharing, car-pooling, demand-responsive transport, car-rental, etc., are services that can complement the classic fixed line- and timetable-bound public transport services and, together with walking, they form a complete and coherent mobility solution. Public transport should no longer consider these forms of mobility as competitive but rather as services that can be mutually beneficial.
