Abstract:The objectives of this research were to explore the current transportation planning process in California, to understand the challenges and opportunities posed by Intelligent Vehicle Highway Systems (IVHS); and to develop a framework for a transportation planning methodology that responds to them. In developing such a methodology, the authors' goal was an integrated computer platform for performing the necessary analysis and modeling involved in planning, as well as for supporting the deliberative processes that are involved in making programming decisions. In this report the authors present the framework for a transportation planning process for the IVHS era, the elements of a transportation planning methodology and the general architecture of a computer platform for integrating analysis and deliberation. They define transportation planning to include the entire range of transportation decision-making regarding transportation improvements and policies. They present a computer model for integrating planning and analysis, called PLANiTS. The proposed planning methodology involves extensive use of knowledge bases in assessing transportation actions. It involves on-line access to knowledge and to modelling capability. By placing the planning process in a computer aided environment, PLANiTS aims to make it more transparent and to give users the opportunity to seek consensus on the basic assumptions, criteria and models of analysis, as well as the programming decisions.
