Abstract
The planning system with three parallel planning processes, in other words, a tri-coinciding planning process is proposed in this paper. The process is composed of technical examination process, planning sequential process and communication process. Although the similar process has already been applied in the guideline of the Ministry of Land, Infrastructure, Transport and Tourism for the rough planning of major infrastructure development, we develop a general framework for the regional plan and the infrastructure plan by considering validity claims based on citizen's needs. We examine the reason of taking those framework and some controversial points of discussion during the planning process, such as the evaluation of alternatives, the causal relation between ends and means.
