MODEL SYSTEMS FOR URBAN TRANSPORTATION PLANNING: WHERE DO WE GO FROM HERE?

A BRIEF SURVEY IS PRESENTED OF THE URBAN TRANSPORTATION PLANNING EFFORTS OF THE PAST AND THOSE CURRENTLY UNDERWAY. FIVE HIDDEN ASSUMPTIONS THAT APPEAR TO UNDERLIE THE ENTIRE PLANNING PROCESS AND ABOUT WHICH THE AUTHOR HAS DOUBTS: (1) THE PURPOSE OF THE PLANNING PROCESS IS THE SELECTION OF THE DESIGN FOR THE URBAN TRANSPORTATION SYSTEM THAT SUPPORTS THE LAND USE ANTICIPATED FOR THE DESIGN YEAR, (2) LAND USE IS NOT AFFECTED BY THE LOCATION OF TRANSPORTATION FACILITIES OR AT LEAST IT CAN BE ASSUMED SO FOR THE PURPOSE OF BUILDING THE TRANSPORTATION MODEL, (3) IN EVALUATING ALTERNATIVE TRANSPORT SYSTEM DESIGN THE DESIRABILITY OF A PARTICULAR SYSTEM CAN BE DETERMINED BY COMPARING FLOWS ON ALTERNATIVE DESIGNS AND ANALYZING THE NET COSTS AND BENEFITS OF THE SYSTEMS, (4) SYSTEM SIMULATION RESULTS MUST BE USED TO HELP SIZE FACILITY DESIGN RAMPS AND PLAN TRAFFIC CONTROL INSTALLATIONS, AND (5) CITIZEN PARTICIPATION IS EXTREMELY DIFFICULT TO INCORPORATE INTO THE TECHNICAL ASPECTS OF TRANSPORTATION PLANNING. THE AUTHOR FEELS THAT THE GREATEST CHALLENGE IS TO EFFECTIVELY PERFORM URBAN TRANSPORTATION PLANNING BY RECOGNIZING THAT CURRENT PLANNING HAS STAGNATED IN THE BUILDING OF NEW MODELS AND IS FAILING TO ADEQUATELY ADDRESS THE PRESSING MODEL-BUILDING ISSUES OF THE CURRENT TIME.
