Abstract:

TRANSPORTATION IMPROVEMENTS ARE SOMETIMES BASED ON ESTIMATES OF UNFULFILLED NEEDS OF PARTICULAR GROUPS. HOWEVER, THE CONCEPT OF NEED (AS DISTINCT FROM THAT OF TRAVEL DEMAND) HAS NOT AS YET BEEN DEFINED WELL. THIS PAPER ANALYZES VARIOUS METHODS OF COMPUTING HOW MUCH TRANSPORTATION PEOPLE NEED. THE USE OF NEED IS DISCUSSED IN THE CONTEXT OF HEALTH SYSTEMS PLANNING AND OTHER DISCIPLINES. AN IN-DEPTH CASE STUDY OF THE TRANSPORTATION NEEDS OF POVERTY GROUPS IN RURAL AREAS IS DISCUSSED TO ILLUSTRATE METHODS OF ARRIVING AT QUANTITATIVE NEED ESTIMATES. WAYS OF DEFINING NECESSARY TRIPS (BY TRIP PURPOSE) ARE DISCUSSED. THE NUMBER OF HOUSEHOLDS NEEDING TRANSPORTATION IS CALCULATED ACCORDING TO THE TRANSPORTATION SERVICES AVAILABLE TO THE HOUSEHOLD AND THE TRANSPORTATION SERVICES THAT THE HOUSEHOLD CAN AFFORD. A SCALE OF FIVE LEVELS OF NEED IS DERIVED FROM TRANSPORT SERVICE AVAILABILITY AND AFFORDABILITY. USING TRAVEL BEHAVIOR DATA COLLECTED THROUGH HOME INTERVIEWS, THE NUMBER OF TRIPS REQUIRED FOR PERSONS IN SEVERAL AREAS OF RURAL POVERTY TO MEET THE AVERAGE U.S. TRAVEL STANDARD IS CALCULATED. THE AMOUNT OF TRIP-MAKING REQUIRED TO MEET SUCH A STANDARD IS SO LARGE THAT IT WAS CONCLUDED THAT THIS MEANS OF CALCULATING NEED WAS IMPRACTICAL. ANOTHER ALTERNATIVE, ALONG THE LINES OF DEMAND AND INCOME-EXPENDITURE ANALYSES, IS PROPOSED FOR FUTURE RESEARCH.
