| Abstract |
In the previous study, it proved considerably effective to apply the notion of visibility, one of the most significant human behavioral property, to the traditional spatial analysis method such as ERAM model. Based on that successful result of the previous study, this study focuses to extend the role of visibility in ERAM model and to propose weighted ERAM model in respect of visibility. ERAM model uses adjacency matrix extracted from the graph of spatial structure, thus it is appropriate to applying the notion of weigh. As an explorative study to apply the notion of weight to Visibility ERAM, this study aims to construct models using weight factor of border and turning angle each and to apply them to actual built-environment. Weight factor of border is proposed to consider the effect of surrounding zone, which is well-known to concerned researchers as 'edge/border effect', and weight factor of turning angle to consider the easiness of directional change, which is meaningful in the human movement behavior. In this way, the weighted visibility ERAM models reflecting both border and turning angle factor is proposed and verified by applying it to actual built-environment and comparing the result with real human movement pattern. |
