Traveling Ego Vehicle is traveling in one Driving Lane

Driving Lane is current path of travel for zero or one Traveling Ego Vehicle


An Ego Vehicle On Road is certainly on the Road, but could be in a Non Driving Lane. The vehicle may be pulled over on the shoulder or it may be in a Shared Single Road Lane. In the latter case, a lane change would be out of the question since there is only one lane in the Road. So, the fact that a Traveling Ego Vehicle is in a Driving Lane is a key qualification for a number of possible behaviors.

A given Driving Lane may or may not be currently occupied by the Ego Vehicle at the moment.
