1. A vehicle communication system in which communications for automated driving control for vehicles is executed according to a zone system;
- said vehicle communication system comprising;
a monitoring means for monitoring an information traffic volume in two or more areas provided in a zone on a road and each having a specified number of channels or a specified number of time slots allocated thereto; and
a controlling means for controlling reallocating, when an information traffic volume in one area of the two or more areas has exceeded a specified value, channels or time slots allocated to other areas of the two or more areas to said one area.

Abstract
An area corresponding to a zone 15 on a road 14 is divided to area A and area B, and an information traffic volume in each area is monitored. When overflow is about to occur, time slots for other areas are temporally allocated to the area to evade the overflow, so that shortage of communication channels due to a traffic jam or for some other reasons can be prevented in a system for providing automated driving controls for vehicles by means of communication systems based on a zone system.
