Abstract:
A method of making a toil turn in a waiting vehicle at an intersection where vehicles travel on the right side of a road, wherein a first oncoming vehicle is entering the intersection and wherein a second oncoming vehicle following the first oncoming vehicle has its left-turn signal on, said method comprising:sensing blinking signals of the left-turn signal of the second oncoming vehicle from a first end of an optical fiber installed linearly along the centerline of the road, said first end being directed facing a driver of the waiting vehicle, wherein the blinking signals are reflected to said first end from a second end of the optical fiber, wherein the optical fiber is longer than the length of the first oncoming vehicle such that said second end is directed to receive the blinking signals of the left-turn signal of the second oncoming vehicle and reflect the light to the first end and the waiting vehicle; the first end of the optical fiber comprises light-emitting diodes and the second end of the optical fiber comprises CDS photoelectric elements; and the waiting vehicle turning left when the driver deems conditions to be said taking into consideration the presence of the blinking signals sensed.
