Abstract
I THINK THAT THE ADVANTAGE OF POSITION IN THE CITY IS AN IMPORTANT FACTOR FOR DEVELOPMENTS, AND HAS BEEN MADE PRIMARILY BY STREET NETWORK. THEN LOOKING UPON STREET NETWORK AS GRAPH AND USING GRAPH THEORY, QUANTITATIVE VALUES WHICH ARE EQUIVALENT TO THE ADVANTAGE OF POSITION HAVE BEEN GOT. THIS PAPER DESCRIBES SOME PRACTICAL USES APPLIED TO REAL STREET NETWORKS(PLANNING ROADS OF KUMAMOTO CITY), AND RESULTS THAT THE DISTRIBUTION OF THESE VALUES SHOWS THE PRESENT STATE AND CHANGE OF NETWORKS OR URBAN STRUCTURE
