The environment in which transportation analysis and infrastructure planning take place has changed dramatically during the last years. The focus is now, to a considerable extent, on how to transform the transportation system in a direction that could be sustainable in the long run, rather than on planning for infrastructure investment to meet new demand. At the same time information technology penetrates all sectors of the society. This will change how the transportation system will be used by travellers and conveyers, both directly, through new products and services, and, indirectly, through a spatial reorganisation of many activities that govern the transport demand. In such a situation it must be questioned whether the analytical tools that may have functioned reasonably well in the past, also are appropriate, or possible to adapt, to be useful for the issues we will face in the future. A survey is made of ideas for model development for travel analysis with an emphasis on activity based models based on an international literature review. The study treats tools for the whole chain from location decisions to network effects. The main focus is on such development that is of interest for a medium-sized city like Stockholm. It stresses demands that might be raised on modelling tools with a background in the planning issues that can expected to be central within the next ten-year period. Different ideas for model development, and existing models that could be considered for implementation, are evaluated with respect to their usefulness for planning, need for resources, demand for competence and data, and obstacles of implementation. Finally, we are suggesting some specific model development that should be tested in Stockholm, including a pilot study concerning the implementation of an activity-based model.
