Transportation Engineering

Subject : engineering
Instructions:
  • Answer 34 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • 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. Curves - curves with spirals - broken back - compound curves - reverse curves






2. Flexible: asphalt concrete; rigid: portland cement concrete






3. Vertical point of curvature; PVC = PVI - g1^2(L)/2






4. Climate conditions - terrain - type of area (rural or urban); and frequency of slow moving vehicles






5. Mobility & Access






6. Average speed of drivers (SMS)






7. Must be able to see far enough to be able to cross the road from a stop






8. Multiple curves connected directly together go from large radii to smaller radii (similar to spiral curves)






9. Superelevation - side friction - radius






10. Asphalt: alligator - longitudinal - reflection - pothole - rutting - pumping --- Concrete: corner breaks - durability cracks - longitudinal crack - joint seal failure - scaling/spalling - blowup






11. Rate per hundred million vehicle miles of travel






12. Sight distance - horizontal alignment - vertical alignment - combo of vert. and horiz. alignment - minimum cross slope - edge radii - ISD - freeway ramp junctions - horiz. and vert. clearances






13. Vertical point of tangency; PVT = PVI + g2^2(L)/2






14. Must be able to see far enough to stop before the intersection






15. Selected speed used to determine the various geometric design features of the roadway (controls your horizontal adn vertical curves)






16. Interstate + Freeway/Expressway - Principal Arterial - Minor Arterial - Collector - Local






17. Rate per million entering vehicles






18. Design for function NOT volume; (Ex. Roads designed only on volume: Briarcrest Drive and Rock Prairie Rd)






19. The distance required to react and brake -- does not impact geometric design until it is applied to the characteristics of design such as vertical curve length






20. Infrastructure - vehicles - operators






21. Speed without any impacts of delay (TMS)






22. Uses parabolic curve for variable radius; length is determined by the rate of change; length along the curve is the projected horizontal distance






23. Provide lateral guidance and support vehicles






24. Principal Arterial (freeway is the highest class) - Minor Arterial - Collector - Local Roads and Streets






25. Interstate - Principal Arterial - Minor Arterial - Major & Minor Collector - Local






26. Roadways: AASHTO Green Book & TxDOT Roadway Design Manual Rail: American Railway Eng. Ass.






27. Two curves with different radii connected back to back in the same direction






28. Term used to describe the way in which highway designers try to fit the highway to the terrain while maintaining design standards fro safety and performance






29. 11.2 fps^2






30. Interchanges or intersections with unexpected or unusal maneuvers; changes in cross sectionl areas of concentrated demand






31. Uses circular curves for constant radius; curves require superelevation; the length is measured along the curve between its beginning and ending point






32. Distance required to permit control of the vehicle to avoid collisions






33. 2.5






34. Grades - length
