Urban Open Space's Accessibility Assessment Using Angular Segment to Reinvent as Evacuation Shelter in Historic City
International Journal of Social Science and Humanity
This paper using a combination toolset consists of GIS and Angular Segment Analysis in the Space syntax theory to reveal the possibility to reinvent urban open spaces in a historic city regards to its type. The objective of this study is to clarify the relation of auspicious urban open spaces and its urban fabric. Study area in this study is Chiang Mai historic city area situated in Northern part of Thailand. According to urban spatial condition of the city, it has been planned within a strong
... ed within a strong geometry shape and deform-grid network. The angular segment analysis was used to analyze approaching and angular distance each typology of urban open spaces. The entry points were retrieved by field survey and input to GIS's data. Then, a result of angular segment analysis will overlay with multiple overlay technic. Finally, these overlay's results will be discussed and revealed, urban open space's angular length and spatial data will be classified to created material for reinventing. The result of the study reveals that the relation between religious spaces and its cultural-urban fabric. Urban fabric related to angular length from religious spaces, reflected the cultural-spatial pattern, simultaneously. These determine that religious spaces in Chiang Mai could be reinvented according to its approaching. Index Terms-Open space, emergency shelter, historic city, space syntax.
