A Model of London and the South East

A general description is presented of how the MEPLAN model has been implemented and used within a study area comprising London and the South East of England. The model operates at a strategic level and represents both the land-use system and the transport system, together with the ways in which these two systems interact to determine the future evolution of the region. There is an explanation of the main theoretical structures included in the MEPLAN model and the way in which these are used to represent the aspects of relevance to the study area. Over the last four years this model has been used by decisionmakers to inform the debate on a wide range of policy issues. These uses of the model are reviewed and conclusions on its worth are drawn.
