If the current trends in transport are not changed, a sustainable transport system is not feasible. In order to achieve such a state, new technologiesmay be an interesting option. In this context several success and failure factors for the introduction of new technologies are analyzed in this article. These possibilities are identified in different areas, notably economic, spatial, institutional, social/psychological and technological fields. Withinthis context the following new options are discussed: the electric car, people movers, subterranean infra-structure, telematics, the high speed train,the high speed maglev train, shuttles in vacuum tunnels and alternative fuels. Finally , some policy choices, which maystimulate future technical developments, are discussed. It is concluded that anactive government policy may stimulate the introduction of new technologies, which may give a substantial contribution to achieving a sustainabletransport system.
