This work has the objective of creating an information service to supply necessary information to mobility handicapped individuals based on a monitoring technique. There are a number of stumbling blocks in a subway station in the routing of infrared rays, supersonic waves, or generic RF signals. In this work we used a space digitization method than triangulation methods using RF signals. We suggest an alternative location positioning method that makes use of a mosaic map. A number of RFIDs are implanted instead of sensors, which are not expensive solution for public facilities.
