This paper is based on the Dutch National Spatial Planning Agency's 'Spatial patterns and transport networks' project. This project reviews how transport networks can be designed and developed in relation to spatial developments. It is concluded that many of the present problems of transport planning, such as congestion, environmental pollution and the growing use of space for traffic, are only partial problems. The structural problem is the inflexibility of space. It is impossible to create a permanent solution for an optimal mutual adjustment between spatial activities and the transport of people. Even if activities have been planned, conditions can be changed so that the planning is no longer applicable. It is argued that an enlargment of the transport planning horizons is necessary. This is possible by: (1) paying more attention to other disciplines and approaches; (2) making a better use of the space and time dimension; and (3) utilising all potential of technology. It is also argued that the main emphasis in transport planning should be given particularly to the integration of space and transport.
