Samenvatting
This paper introduces the service descriptions of driver support safety systems (DSSS), and discusses the advantage of utilizing the radio waves for some of those systems. The radio waves can broadcast information continuously while infrared beacon communicates once in a spot area. Right-turn Collision Prevention System is supposed to be one of more effective systemsin case of using the radio waves and its functionality with the radio waves is verified. The basic characteristic tests are also conducted for DSRCof 5.8GHz band and New Radio systems of 700MHz band, which are the candidates of the radio waves for DSSS in Japan.
