Abstract

Disclosed is a pedestrian support system that supports the movement of a pedestrian through the use of tags. This pedestrian support system comprises: a plurality of tags having an information storage unit and that are placed on a cable that extends over a traveled path; a guide device that is held by a pedestrian that is traveling along a sidewalk and that is capable of non-contact communication with the tags, and a central control device, comprising a database in which tag map information is recorded, that uses that tag map information to creates path information having tag IDs that are in the order of tags that are located along a path from a starting location to a destination location and directly or indirectly sets that path information in the guide device. The guide device reads the tag IDs from the tags, compares the read tag IDs with the tag IDs in the path information to identify the location on the path where the pedestrian is walking, and provides information such as advancement direction to support the movement of the pedestrian.
