    Abstract: The present invention relates to a communication system which can effectively avoid congestion in ITS communications at a street intersection to properly assist the driving of autonomous vehicles. An information source roadside apparatus 3 acquires terminal movement information on movement directions of nearby pedestrian terminals, and transmits the information to an information destination roadside apparatus, which determines, based on the received information, if there is predicted congestion in the terminal-to-terminal communications at a predetermined future time. When determining that there is predicted congestion, the information destination roadside apparatus transmits an instruction for a congestion avoidance operation to the pedestrian terminals 1. Then, each pedestrian terminal performs the congestion avoidance operation by switching a communication mode from a direct communication mode using the terminal-to-terminal communications, to an indirect communication mode using communications via a roadside apparatus.

    Abstract: Provided is a system which can reduce load on a travel controller that performs a danger avoidance operation by preliminarily detecting a significant event without increasing an amount of ITS communications, thereby providing suitable assistance for travel control of autonomous vehicles. When a vehicle 1 passes through a certain section of a road after an in-vehicle terminal 4 has detected a significant event while the vehicle 1 is traveling in the section, the in-vehicle terminal 4 transmits event data (images and other information related to the event) to a roadside apparatus 6 at an end point of the section. The roadside apparatus 6 transmits the event data to another roadside apparatus 6 at a start point of the section, which in turn transmits the event data to an in-vehicle device in another vehicle entering the section so that the device can perform travel control based on the event data.
