Abstract
The present disclosure teaches inter-vehicle communications for avoiding rear collision of rail vehicles on a railroad. For example, a collision avoidance system may comprise an end-of-train device and a V-aware unit located on different vehicles. The two devices may be configured to wirelessly communicate with each other, and then detect each other's presence by estimating a distance between them. Warnings may be issued to respective operators against a collision hazard when the distance drops to or below a pre-determined threshold.
