VEHICLE COLLISION AVOIDANCE SYSTEM ABSTRACT OF THE DISCLOSURE An automatically guided vehicle (110) is disclosed which follows guide lines positioned in a predetermined guide path (102) on the floor. The guide path (102) includes coded markings and the vehicle comprises sensing circuitry (210) capable of sensing the markings and generating proximity signals indicative thereof. The coded markings can indicate approach of the vehicle into a "congestion" zone wherein other vehicles similarly situated can cause hazardous condi- tions therein. Radio frequency (RF) transmission circuitry (240) on the approaching vehicle (110) is responsive to the congestion zone indication signals to transmit and receive RF signals to and from other vehicles on the guide path (102). The approaching vehicle (110) performs various collision avoidance operations as determined by the received RF signals.
