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