Along with an aging society, the term "barrier free" has begun to be used. When disabled set out to reach their chosen destination, various kinds of barriers exist. In order to remove them and guarantee "freedom of movement", it is necessary to arrange for sidewalks and roads to be continuous. However, it is difficult to arrange for the removal of all barriers in an existing city. The purpose of this study is to develop the system of providing information which enables the disabled to judge the route to their destination in person. Furthermore, we grasp current problems and examine a possibility of the priority determination system of improvement of barriers by the system of providing information. An important requirement when providing information is facilitating incorporation of new data according to needs, so systemized provision of information becomes necessary. This time, for the purpose of making this system, a series of flows ranging from collecting of information to production was performed. Since realization of the idea was the main point and some parts were easily modeled, there are some problems such as collecting of information, set up of an evaluation value, the structure of the program, etc. However, this system can be gradually applied and made highly suitable for general purposes by improvement in each step and the whole system.
