Figure 1 is a plan view of the intersection. 1 is the intersection point where the ultrasonic receiver of the present invention is embedded, and 2 is the ultrasonic receiver in the center of the intersection point. 'Figure 2 is a side view of the ultrasonic receiver. 3 is a shelter 14 for preventing erroneous reception of ultrasonic waves from other directions, which is an ultrasonic wave receiving window. In FIG. 3, the internal circuit of the receiver 5 is a wave detection circuit, 6 is a first-come-first-served priority determining circuit, 7 is a conversion amplification circuit, and 8 is an output circuit to a traffic signal operating circuit.
