REFLECTIONS ON CONCEPTS FOR IMPACT RESEARCH

THE ECONOMIC EFFECTS OR IMPACTS OF HIGHWAY IMPROVEMENTS HAVE RECEIVED AN INCREASING SHARE OF RESEARCH IN THE AREA OF TRANSPORTATION AND LOCATION IN RECENT YEARS. ALTHOUGH SUBSTANTIAL PROGRESS HAS BEEN MADE TOWARD IDENTIFICATION AND MEASUREMENT OF CHANGES WHICH FOLLOW HIGHWAY ADDITIONS, MUCH REMAINS TO BE DONE IN EXPLAINING HOW AND WHY THESE CHANGES OCCUR AND WHO OR WHAT GROUPS ARE AFFECTED AND HOW. IT IS BELIEVED THAT THE EXPLANATION OF HIGHWAY IMPACTS AND THEIR INCIDENCE CAN BE AIDED BY TAKING A LOOK AT CERTAIN ESSENTIALLY CONCEPTUAL QUESTIONS WHICH SHOULD BE DEALT WITH IN THE PLANNING STAGE OF NEARLY EVERY HIGHWAY ECONOMIC IMPACT STUDY. THIS PAPER DISCUSSES AND OFFERS TENTATIVE ANSWERS TO THE FOLLOWING FOUR QUESTIONS WHICH THE AUTHORS HAVE FOUND TROUBLESOME: (1) WHAT FUNDAMENTALLY IS MEANT BY IMPACT, AND HOW AND WHY SHOULD IMPACTS BE TRACED? (2) IS THERE A VALID AND THEORETICALLY DEFENSIBLE DISTINCTION BETWEEN REDISTRIBUTIVE EFFECTS AND BENEFITS? (3) HOW SHOULD THE AREA OF IMPACT FOR HIGHWAY ECONOMIC STUDIES BE DEFINED? AND (4) WHAT CONSTITUTES AN APPROPRIATE TIME SPAN FOR INCLUSION IN THE STUDY OF ECONOMIC IMPACTS? THE MAIN PURPOSE OF THIS PAPER IS TO SHOW THAT THE KINDS OF IMPACT STUDIES MADE SHOULD DEPEND ON THE ANSWERS TO THESE QUESTIONS AND THAT THE STUDIES WHICH ARE SUGGESTED BY THE VIEW ADOPTED HERE MAY WELL PROVE TO BE MORE FRUITFUL THAN THOSE OF THE PAST. /AUTHOR/
