For low vision travelers, independent mobility is almost essential to access basic servicesin urban environments. In the context of this study, independent mobility may be defined by itsthree basic components: the physical ability of the traveler, cognitive knowledge, andenvironmental conditions of the travel landscape. Each of these components is associated withspecific potential problems that relate to, or can be represented by, geographic features. Thisresearch utilizes spatial data analysis and modeling techniques to rate urban environments inregards to individuals with visual impairments. A case study is conducted to illustrate themodeling procedures.
