Background Info: Mainline design speed - 70 mph Local Street design speed = 45 mph: Point A: Elev is 950", the entering grade is -2%. Ponit B. Elev is 950", the exiting grade is -3% Point C: Elev is 968,23 Street segment CD is on a upgrade of 1% 2 XY-1.1 X.Y-1.10 A. Mainline Geometric Design For mainline geometric design, you are only required to design the appropriate vertical curves based on above given point information (A, B, C). The vertical curves need to satisfy Caltrans standards of SSD minimum curve length, and vertical clear ance, etc. You curve design shall be shown in given profiles of the original design files. Your supplementary report shall document the necessary curve length calculation and demonstrate the compliance with Caltrans standards.
