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: Regarding display of browsing information on a portable terminal, it is possible to impose a browsing restriction on a person who does not have a browsing authorization with a simple configuration while avoiding a hindrance to easy access to the browsing information. An information browsing system includes: one or more transmitters that respectively transmit wireless signals including transmitter identification information which is identification information of the transmitter toward a target area; a portable terminal that holds terminal identification information and receives the wireless signal; a storage that accumulates browsing information isplayable on the portable terminal; and a server that provides the browsing information to the portable terminal by communicably connecting to the portable terminal, in which at least one of the portable terminal and the server determines whether or not to display the browsing information on the portable terminal based on a combination of the transmitter and terminal identification information.

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.
