AN ANALYSIS OF THE CAR-OWNERSHIP CONSCIOUSNESS AND AN EVALUATION OF THE ROAD NETWORK PLANNING BY SHANNON'S ENTROPY

Abstract

By introducing new concepts of virtual information element (VIE) and opportunity benefit, we constructed new models being appropriate for analyzing questionnaires and evaluating the road network planning in terms of opportunity. Using Shannon's entropy, (VIF-1, VIE-2) diagram is analyzed, and opportunity index is evaluated. The new models are applied for the analysis of the car-ownership consciousness and the evaluation of the road network planning in terms of opportunity in East Region of Hokkaido. It is shown that the car-ownership consciousness are classified into two classes and that the access-opportunity may be increased by the road network construction planning between Akan and Shibecha.
