5. If TTL is Total Tangent Length, TL is Tangent Length, T is Curve Tangent, L is Curve Length, which formula will calculate the correct PI station of Curve 2 on SR25? @ from the PT of curve 1, add the TL2 tangent length to get the PC2 Sta, then add T2 to get the PI2 station. a. PI2 Station = PT1 Sta + TTL2. b. PI2 Station = PI1 Sta + TTL2 ................
