STUDY OF URBAN STREET NETWORK WITH BUILDING NODES

Abstract

Studies on urban networks often focus only on street systems, such as streets as links and junctions as nodes. Attentions to the buildings are hardly paid, though they are the starting/ending nodes of human flows, and the most influential elements in the urban networks. This paper proposes the "Building-Street Network", which integrates buildings as urban nodes, and can be evaluable with the weights of the building attributes like the total floor area. By using the indices of Betweenness Centrality that shows the characteristic structure of urban network, the evaluation of weighted Builiding-Street Network of districts in Tokyo is made, to show the correlation to the building attributes.
