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 vehicle dispatching system that reduces burden on users. A roadside apparatus 4 detects a vehicle waiting person based on images captured by a camera 13, acquires the person's position data; sets a pickup point based on the person's position data and map data, acquires the pickup point's position data, and transmit it to a server 5. The server selects a vehicle to be dispatched for the person according to a positional relationship between the vehicle and the pickup point, and transmits the pickup point's position data to an in-vehicle terminal 2. The in-vehicle device or the roadside apparatus performs control so that the vehicle moves to the pickup point, when determining, based on the pickup point's position data and the map data, that a lane closest to the pickup point is for the same traveling direction as a lane in which the vehicle is traveling.

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.
