Q4.1.1 Which two horizontal curves have the lowest Effective Design Speed? - Horizontal curves have the same speed, 50mph, throughout the road. Q 4.1.2: Which two vertical curves have the lowest Effective Design speed ? The segments of road with grades ranging from 73+81.89 to 77+09.974, and from 80+38.058 to 83+66.142, have been designed to accommodate lower effective speeds of 33mph and 26mph, respectively. Specifically, the first segment is a crest curve, while the second one is a sag curve.

Q4.1.3 In each direction of travel (decreasing and increasing), identify the segment with the shortest available Stopping Sight Distance. - The stopping sight distance is at its minimum in two segments of the road: between 41+58.00 and 45+60.00, and between 101+82.00 and 107+10.00. In the former segment, the stopping sight distance is 198ft, while in the latter, it is 180ft.
