5700 MHz ITS

Collisions tend to occur at intersections

with poor visibility for drivers, such as in

residential areas.

Visibility for drivers is degenerated due to trees, walls, or other obstructions.

Visibility is poor!

Another vehicle

Driver’s vehicle

ITU-R Report M.2228

“Advanced ITS

ITS alert drivers through alarm sounds, heads-up display, and voice message.

A vehicle is approaching from the left !

Many traffic accidents happen at intersections in Japan.

700 MHz ITS are useful for avoiding such accidents at intersections.
