USE OF TWO-WAY BEACONS IN ROAD MANAGEMENT--EXPANSION OF VEHICLE INFORMATION AND COMMUNICATION SYSTEM FUNCTIONS

This report discusses the use of two-way beacons in road and vehicle communication systems to realize advanced road management services. The vehicle information and communication system (VICS) is an emerging technology expected to become practical in the near future in Japan. While one-way beacons have been used in VICS projects in the demonstration phase, these beacons are further evolving into two-way beacons that mediate communications between road facilities and vehicles. The development efforts in this field have entered the stage of technical verification. Expected improvement of two-way road and vehicle communications will facilitate more advanced road management, traffic control, and freight management. Currently, road management services heavily depend on wireless transmission including road traffic information, service management information, and instructions to management vehicles. The quality and efficiency of these services can be improved by timely and flexible transmission of data designed to deal with both scheduled and nonscheduled patterns of services. Two-way beacons are effective in ensuring the promptness and flexibility of data transmission. It is necessary to construct a system integrating communications using two-way beacons, communications using existing wireless systems, and batch processing, either combined or used separately for suitable purposes. An important factor is the timing of the introduction of this system.
