Urban land-use models: The determinants of adoption and use

This paper delineates the conditions under which computerized land-use models have been adopted and used in the activities of a number of regional planning agencies. Our discussion is based on intensive case studies of planning agencies and the group includes both model adopters and nonadopters.We find that the presence of advocates of model adoption and of persons interested in their continued refinement and use are of paramount importance in the decision to adopt a model and in its subsequent incorporation into the life of the planning agency. However, although the presence of an advocate is by-and-large sufficient for model adoption, the continued interest of agency staff is necessary but far from sufficient in determining how and to what extent the model will in fact be exercised. At this stage both political and organizational factors become important. Moreover, it is at the use stage, rather than at the consideration of adoption, that the characteristics of the model receive more careful scrutiny and shortcomings become more important.This research has been supported by a grant from the Research Applied to National Needs Division, National Science Foundation (SSH74-19323).
