A humanoid cop at an intersection may not be the thing. A smart traffic control system with AI may be what may have to be looked at. However, that will be too big for a B Tech project.

as per your interest you will sure find a suitable project for you , though they are too difficult as per btech level ..
but if you go through will sure help and give you a good sight and leads you a good engineer.
