 Abstract
This study aimed to propose the method and process of applying more than two weighting concepts to ERAM model integratedly. First, the existing methods of applying a weighting concept to ERAM model was examined, and the necessity of applying multiply weighting to ERAM model was considered. Second, as the method of applying more than two weighting concepts to ERAM model integratedly, what is called multi-weighted ERAM model, this study proposed the method of setting each entry of an weighted adjacency matrix as a multiplication result of different weighting values pertaining to the position of the entry, that is, . This method has the advantage that relative ratio of each weighting concept can be reflected in an integrated weighting value. Third, this study also proposed multi-weighted ERAM model of applying both distance and angle. Fourth, this study verified the distance & angular multi-weighted ERAM model. For the verification, Myeong-dong, Insa-dong and Seoul City Hall area were selected as analysis targets, and non-weighted(original) ERAM model, angular weighted ERAM model, distance weighted ERAM model, and distance & angular multi-weighted ERAM model were applied to analyses of each target area, and finally the correlation tests between the analysis result of each model and the pedestrian movement density data on each target area. As a result, the explanation ability of distance & angular multi-weighted ERAM model on the pedestrian movement density proved to be better than those of the order models.
