Unable to track single vehicle to compute distance traversed by it

I have successfully detected the vehicles with my algorithm,now I want to calculate the speed of vehicle(s)

as u see in the figure , I am having more than one vehicles in each frame with new vehicles adding in the new frames.So it's becoming very difficult to track single vehicle (say leftside car in the image which is coming towards us) and calculate its centroid at different frames.

So how should i avoid other vehicles to calculate pixel distance traversed by the single vehicle? Thank u in advance

YOu need to know the distances and then measure how many pixels are between them. For example, what is the distance between the poles in real world units, and in pixels?

If they're merged together you can try to separate them with watershed() or imopen().

@Image Analyst sir can u send me algorithm or matlab code to separate them with watershed() or imopen() for above images
