VARIABLE ROAD CONDITION INFORMATION PRESENTATION METHOD AND VARIABLE ROAD CONDITION INFORMATION BOARD

摘要

PROBLEM TO BE SOLVED: To provide a variable road condition information presentation method and a variable road condition information board by which sufficient attention is called by informing a driver on a car at a sub-road side of information on an approaching car at a main road side at a traffic signal-free intersection, and no traffic flow is disordered without stopping the car at the main road side. SOLUTION: The variable road condition information board 5 is located on the upper portion of a pole 8 installed in such a manner that the driver on the car 6 at the sub-road 2 side may see the variable road condition information board at the traffic signal-free intersection 3. The car 10 approaching the intersection 3 is detected by using a car sensor 11 installed at the main road 1 side at its left approaching side. Pedestrians and bicycles are detected by using a pedestrian sensor 12 installed at the vicinity of the intersection 3 at the main road 1 side. Displaying the approach on the variable road condition information board 5 calls the attention to the driver on the car 6 at the sub-road 2 side. COPYRIGHT: (C)2004,JPO&NCIPI
