Abstract

We have developed a high-accuracy pedestrian positioning information system named P-POINTS (Personal Positioning INformaTion System). This system is characterized by highly accurate position detection and seamless indoor/outdoor utilization, these benefits not offered by conventional position detection systems. P-POINTS employs pico cells to improve its accuracy. Owing to the small coverage area of each cell, the resolution of position detection can be increased. It is also suitable in extending the service area such as inside of buildings or underground areas. These features make it attractive to realize pedestrian support in an ITS service
