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. Provide lateral guidance and support vehicles






2. Mobility & Access






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






4. 2.5






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






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






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






8. Superelevation - side friction - radius






9. Rate per million entering vehicles






10. 11.2 fps^2






11. 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






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






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






14. 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






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






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






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






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






19. Average speed of drivers (SMS)






20. Infrastructure - vehicles - operators






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






22. Curves - curves with spirals - broken back - compound curves - reverse curves






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






24. 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






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






26. Grades - length






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






28. Speed without any impacts of delay (TMS)






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






30. Rate per hundred million vehicle miles of travel






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






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






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






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