Abstract
In this paper, system for participatory planning, in which plural participants are involved in the process for planning and making decisions, is discussed. Then, the model for describing conflicts which can arise in participatory planning is proposed. First, the problems of game theory in describing conflicts in participatory planning are discussed. Second, policy conflict model is proposed. Based on the proposed model, typology of conflicts between participants is shown. Schemes for governing such conflicts are also considered. Finally, the proposed methodologies are applied to the problem on regional public transportation planning.
