| Abstract |
ERAM theory is an analytical tool for spatial configuration of architectural and urban spaces such as Space Syntax model. In this study, we tried (1) to reinterpret ERAM theory in terms of Markov process which is a kind of stochastic process and (2) to compare ERAM theory with Space Syntax model using pedestrian movement data. Besides, a new quantitative index ERAM and ERAM(r) for the spatial attribute is suggested. The results of the study include the followings. From the reinterpretation of ERAM theory, it can be said that ERAM theory is well compatible with stochastic process. From the comparison of integration and ERAM, it can be said that ERAM reflects the spatial configuration better than integration. Therefore, ERAM analysis can be used as a powerful tool for predicting accessibility of architectural and urban spaces. |
