Seriously ... I think people should put some effort into their problems ... the solution is as simple as your question ...

Vow! how u do that(Nice Animation), but i already using optical flow with Lucas-Kanade method, in this i stuck on multiple vehicle. Can we find the direction using centriod (on multiple vehicle)....

Yes you can, just keep track of the centroid Y and X coordinate. The change in direction gives you movement ...

Yes, i done that, but inbetween with multiple vehicle (in same direction) the centroid will overlab.. Y:125 Y:129 Y:135 Y:75 Y:59 Y:62

That is why you assign a tracker like kalman or optical flow for each position, to track the correct centroid instead of switching between them.
