What is super-elevation?
Think about how a bike leans while taking a turn.
What is a transition curve?
Consider how highways curve gently rather than sharply.
What is the main purpose of super-elevation?
Think about physics of turning and forces at play.
True or False: Vertical curves have no effect on stopping sight distance.
Consider how elevation changes might block sight.
Design a transition curve for a road with a radius of 200 m and a speed limit of 60 km/h, ensuring comfort under standard parameters.
Study the length and rates provided in the content for parameters.
A highway has a vertical curve changing from a 3% upgrade to a 2% downgrade. Calculate the parameters needed for a smooth transition.
Keep in mind the grade change details.
