EMPIRICAL STUDY OF RELATION BETWEEN USABILITY AND ACCESSIBILITY ON STREETS IN A NETWORK

Abstract

On planning streets network, it is required to secure traffic function for each street corresponding to its practical usability. In this background, though Space Syntax Theory which enables us quantitatively to evaluate accessibility that differs from emphasized concept on designing streets network like classification and capacity so far is recently pointed out, relation between accessibility of this theory and usability of streets in network is not explained clearly by existent research.
In this research, we analyze which Integration Value and Betweenness Value which are quantified by Segment Angular Analysis in Space Syntax Theory possess what kind of relations with usability. Result of this research, it are revealed that Integration Value relates with total usability on the street and Betweenness Value relates with diversity of organ and destination of trips using the street.
