Question 1.
What is the purpose of super-elevation in road design?
Show hintHide hint
Think about the forces acting on vehicles in motion.
Question 2.
Define design speed in the context of road design.
Show hintHide hint
Consider what influences road geometry.
3Question 3.
What is the primary role of super-elevation in road design?
- To increase vehicle speed
- To reduce centrifugal force
- To establish road aesthetics
Show hintHide hint
Think about forces at play during cornering.
4Question 4.
True or False: Higher design speeds require greater super-elevation.
- True
- False
Show hintHide hint
Recall your understanding of how speed affects road design.
Question 5.
Design a theoretical curve for a highway with a design speed of 100 km/h. Consider all factors that need to be included to ensure safety and efficiency.
Show hintHide hint
Use the formulas we discussed about super-elevation.
Question 6.
Evaluate a case where a vehicle experienced an accident on a curve. Discuss factors that could have been improved in road design to prevent such incidents.
Show hintHide hint
Consider what forces were likely at play during the accident.
