Paper Abstract

Pedestrian are one main component in urban space, and it's they that influence and determine urban layout. Spatial visibility analysis is a novel method in urban morphology and spatial configuration. Spatial visibility analysis in urban morphology mainly studies on spatial features (street network for instance) in the city configuration and visibility with humans in it. Through building the visibility of urban space, we can predict pedestrians flow movement trends to analyze the spatial modes. We hypothesis individuals move on street network and change their ways of movement at road crosses with viewshed directions. We can apply the isovist or viewshed to direct their behaviors, and we can analyze the distribution of pedestrian flows potentially. In urban planning, the distribution of facility locations must be consistent with pedestrian flows, and we can offer the estimate through the approach above. The paper first discusses the principle of pedestrian behaviors based on viewshed and the concepts of visibility centricity, then quantifies the parameters of visibility analysis on viewpoints to explore urban morphology of street network of WUHAN ZHONGNAN district. We extract the viewpoints with higher value and draw their distribution map. At the same time we survey the pedestrian facilities locations in city. This paper reveals the consistent relationship between them and demonstrates the influences of geometric features on pedestrian facilities locations over metropolitan's areas based one visibility analysis.
