A STUDY OF RELATION BETWEEN THE HISTORICAL CHARACTER AND USABILITY ON STREET PATTERN BY APPLYING SPACE SYNTAX

Abstract

 Existing urban space is constructed of a variety of streets that have the unique historical characters, for example old paths existing from pre-modern age, urban roads authorized in city plan, small allays built by urban sprawl. On the other hand, each street currently has usability on street network such as main street, commercial street, grid road in residential district. On planning street network, it is important to demonstrate the relation between these characteristics.
 The study field is Meguro Ward, Shibuya Ward and the periphery, where the urban area of Tokyo has exploded during modernization. In this study, we analyzed old edition topographic maps to identify the construction age of each street and applied Space Syntax to analyze the betweenness usability on street pattern. And then, we calculate the correlation ratio between these indices. As a result, it is revealed that older age streets have higher value of betweenness usability on neighborhood scale.
