Abstract:
Research and practice have produced valuable recommendations on transport infrastructure elements or programs that can contribute towards more sustainable urban transport development (see Schiller, Bruun & Kenworthy 2010 for a comprehensive overview). However, conflicting values and competing interests among stakeholders in the transport policy process often create barriers to the implementation of these policies (Baumann & White 2010a). These transport stakeholders range from community organisations through to business interest groups, infrastructure and service providers and pedestrian, cyclist and motorist associations. Problem situations like these, for which there are no solutions that completely satisfy all parties, are often referred to as wicked problem (Rittel & Webber 1973).
