Constructing Indices Representing Physical Attributes for Walking in Urban Neighborhood Area

摘要

Physical attributes for walkable urban neighborhood required summary of indices. The development of indices is based on hierarchy of walking need theory which applies dimensions of accessibility, safety, comfort and pleasurability. The aim of this research is to construct indices of physical attributes by detecting differential item functioning (DIF) base on respondent's demographic factors and their perceived environment. The findings using the Rasch model has dropped 16 items and maintains 20 items that reliable to gauge the 4 dimensions. This research could be used to obtain indices in a justly manner and become an indicator for walkable urban neighbourhood model.
