1- We have Four traffic lights in 4 intersections (A +A1), (B+B1), (C+C1) and (D+D1)
A You go Straight and A1 you go left, B you go straight and B1 you go right and so on...
1- So if (A+A1) starts first and then stops then (B+B1) the (C+C1) then (D+D1) and so on how much time will it take
2- And if A + B will go together then A1 + B1 , and C+D then C1+D1 and so on... how much time will it take??
Which is faster Number 1 or 2?? which is more effective???
