DEVELOPMENT OF INTELLIGENT DELINEATOR SYSTEM

Reduced visibility caused by blowing snow on highways changes so quickly by place and time that it's very difficult to figure out the conditions in detail and provide drivers with appropriate information. When a driver stops his car because of an accident or difficulty in driving, the driver must let followers know immediately. But it's also extremely difficult and can be one cause of multiple-vehicle collision in winter. The authors developed the intelligent delineator system, which is a light-emitting delineator incorporating a pole-type visibility meter and a car halt surveillance radar. When visibility is reduced, it emits light automatically to call drivers' attention, and automatically detects vehicles halted and warns the followers. A pole-type visibility meter was developed first, then a car halt surveillance radar for the system was developed, and their performances were examined. In addition, the light-emitting delineator with a pole-type visibility meter at a median strip on a national hgihway near Sapporo was installed in the 1994/95 winter for an on-site test. Test results determined that the pole-type visibility meter has sufficient accuracy and stability in operation, and the car halt surveillance radar has enough possibility for future practical development. This paper reports on the system development and the on-site test results of the light-emitting delineator system with pole-type visibility meter, which already reached the practical use stage, and also addresses development challenges and future prospects.
