What is a summit curve?
Think about where the road meets an incline.
Why is sight distance important in road design?
Consider visibility requirements for vehicles.
What is the main purpose of summit curves?
Think about the shape and function of the curve.
True or False: A taller obstruction requires a shorter sight distance.
Reflect on visibility and driver safety.
You design a road with a summit curve where L = 300 m. Given h1 = 1.2 m and h2 = 0.15 m, calculate the minimum sight distance S.
Pay attention to units when calculating.
Explain how changing h1 to 1.5 m while keeping h2 constant at 0.15 m affects your sight distance in a summit curve design.
Think about visibility created by height.
