Development of Planning Support System for Welfare Urban Design – Optimal Route Finding for Wheelchair Users

We are developing a planning support system for welfare urban design. If we quantify the optimal route (the route that is the easiest to pass through) for challenged people, we will be able to select the areas that require adjustment in terms of accessibility with greater efficiency. In this paper we report on our development of the prototype system to present an optimal route for wheelchair users, and also, the two workshops we had for evaluating the accuracy of the resulted optimal route.
