Abstract:
This paper aims to propose a route navigation method for disabled access GIS. We focused the disabledâ€™s psychologies as well as their physical conditions. This paper represents quantization of physical and psychological burden of the disabled persons inflicted by various barrier factors. Also it represents estimation of total burden of a route to determine the optimum route. The route is represent ed by graph theory and route navigation method which is based on Dijkstra algorithm is applied. We extend the algorithm to make it possible to provide information on obstacles even when there are no accessible routes available to destination. The result of this study is being implemented and published as 3D Web Disabled Access GIS.
