How about changing the dot representing the person into a triangle indicating the direction travelled? So the path has the triangle pointing away from the path, and the route has the triangle pointing at the route. Also, the destination on the route icon could be an X maybe? EDIT: The path should also be the reverse of the route. That is, the "this is you" marker should be at one end of the line for path and at the other end for route. I'm thinking the bottom of the icon for path.
