Intelligent driving lane with RF-ID for vehicle navigation system

Abstract

In our residential area, northern part of Japan, we sometime meet heavy snow fall and are put into low visible condition due to the snowstorm. Unfortunately, some drivers go out from their driving lane. In order to prevent, such traffic accidents with low visible condition, we developed a vehicle navigation system with UHF RF-ID system. There are several studies related on lane departure warning and vehicle positioning. Some of them uses GPS, DSRC, and other technique, and are some application of triangular surveying. Our navigation system finds vehicle position using information written on RF-ID tag buried under the road surface. From the view point of lane support system, buried RF-ID tags has capability to make the driving lane intelligent with driving support information. In this paper, our navigation system will be shown on this viewpoint.
