Yes.hi,
So you want to count cars as they go In and Out of a Car Parking Gate.?
As well as a Photo Transistor detector you need a Photo Emitter.
Is this a Homework problem.?

hi vtc,
As it is Homework I will not give you the answer to the problem, only hints
Look at this diagram, it should give you an idea how to make the counters, count up and down and the logic circuit required.
