Think about safety on curves.
4Question 4.
True or False: A larger curve radius typically requires a smaller setback distance.
- True
- False
Show hintHide hint
Consider how the geometry of the curve affects visibility.
Question 5.
You are designing a road section with a curve radius of 300m. If the sight distance needed is 120m, calculate the setback distance required. Use appropriate formulas.
Show hintHide hint
Think about sight distance's role in defining safety.
