Operating Speed is?
The speed the road is designed at.

The speed the road allows you to drive at.
The speed the driver wants to drive at.
Design speed is?
The same as the posted speed.
Generally higher than the posted speed.

The desirable method for setting out curves is by?
Offsets from tangents (x and y)
Polar rays (tangential angles)
Coordinates
All of the above
Why is superelevation mainly used?
To improve the appearance of a curve.
To help vehicles around the curve safely.
More comfortable for the driver.
To help vehicles 'cut the corner' and therefore reduce the distance they need to travel.
Point M on a superelevation development profile is when?
The superelevation is at normal camber (-3%, -3%)

The superelevation is at full development.
CS is?
Common Spiral point.

Circular-Straight point
Calculated Superelevation
An objective for Geometric Design is to?
