2.3.4. Methods of horizontal curve setting

Try these first

1. 1.

   What is the primary tool used in linear methods?

   Hint

   Consider the basic tools for measurements.

2. 2.

   Name two methods for setting horizontal curves.

   Hint

   Think about the types of methods discussed.

3. 3.

   Which method relies primarily on chains and tapes?

   • Angular Methods
   • Linear Methods
   • Both

   Hint

   Consider the simpler toolset used.

4. 4.

   True or False: The deflection angle is simply the intersection angle.

   • True
   • False

   Hint

   Think about how angles are defined in curve setting.

5. 5.

   A curve requires a 30m radius. If the intersection angle at point B is 90°, calculate the tangent lengths and deflection angle required for setup.

   Hint

   Use the tangential formula for computing lengths.

6. 6.

   You have two methods available for a project. How would you decide the appropriateness of each in setting curves for high-speed rail versus a local road?

   Hint

   Evaluate the context and speed requirements of the vehicles involved.
