.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Grades - length
Intersection Sight Distance
broken back
veritcal alignment
Approach sight triangle
2. Uses parabolic curve for variable radius; length is determined by the rate of change; length along the curve is the projected horizontal distance
Standard deceleration rate for SSD braking
Function of Roads
Vertical Curves
Urban Functional Classes
3. Selected speed used to determine the various geometric design features of the roadway (controls your horizontal adn vertical curves)
Types of pavement surfaces
Design Speed
veritcal alignment
Superelevation is controlled by 4 factors
4. Must be able to see far enough to be able to cross the road from a stop
Departure sight triangle
Rural Functional Classes
Superelevation is controlled by 4 factors
Approach sight triangle
5. Multiple curves connected directly together go from large radii to smaller radii (similar to spiral curves)
Operating Speed
Horizontal Curves
Superelevation is controlled by 4 factors
compound curves
6. Curves - curves with spirals - broken back - compound curves - reverse curves

7. Uses circular curves for constant radius; curves require superelevation; the length is measured along the curve between its beginning and ending point
Horizontal Curves
veritcal alignment
Approach sight triangle
Stopping Sight Distance
8. Interchanges or intersections with unexpected or unusal maneuvers; changes in cross sectionl areas of concentrated demand
