11Summary

1. VICS and ETC systems have come into widely used.

2. IT Strategic Headquarters newly declared ITS policies and roadmaps

(e.g. “Promotion of automotive safety” and “The greening of the

movement of persons and goods” ).

In Japan…

3. The 700 MHz band is allocated for advanced Driving Safety Support

Systems.

4. 79 GHz band High-Resolution Radar needs spectrum allocation and

discussion of its interference issues.
