PLANNING URBAN TRANSPORTATION SYSTEMS

THIS PAPER FORMULATES THE CONCEPT OF A GENERALIZED PLANNING FRAMEWORK WHICH CAN BE USED AS A BASIS FOR STRUCTURING A LARGE CLASS OF PLANNING AND DESIGN PROBLEMS. THE PHASES OF THIS FRAMEWORK ARE DEFINED AND THEIR INTER- RELATIONSHIPS ESTABLISHED. THE ROLE OF TRANSPORTATION PLANNING IN THE TOTAL URBAN PLANNING PROCESS IS DISCUSSED AND RECENT DEVELOPMENTS IN FORMAL LAND USE MODELS ARE REVIEWED. EXISTING KNOWLEDGE ON THE FUNCTIONAL PLANNING OF URBAN TRANSPORTATION SYSTEMS IS REVIEWED IN TERMS OF THE GENERALIZED PLANNING FRAMEWORK AND THE MAJOR GAPS IN THIS KNOWLEDGE ARE POINTED OUT. THE PLANNING PROCESS DESCRIBED IN THIS PAPER IS MORE COMPREHENSIVE THAN THAT TRADITIONALLY USED IN METROPOLITAN TRANSPORTATION STUDIES. THE MANNER IN WHICH IT IS STRUCTURED PROVIDES A BASIS FOR THE INCORPORATION OF NEW INFORMATION ON ANY ELEMENT OF THE PLANNING PROCESS WITHOUT REVISING THE COMPLETE PLANNING PROCESS. /AUTHOR/
