INTERSECTION COLLISION AVOIDANCE SYSTEM

An intersection collision avoidance system includes a warning device and at least one detection device, wherein: each detection device of the at least one detection device comprises a pair of sensors to distinguish a direction of movement of a person or vehicle from between movement along a first pathway toward an intersection and movement along the first pathway away from the intersection; and the warning device provides a visual and/or audible warning to another person or vehicle moving along a second pathway toward the intersection of likely imminent entry of the person or vehicle into the intersection in response to detection, by one of the at least two detection devices, of the person or vehicle moving toward the intersection along the first pathway.
