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






2. Mobility & Access






3. Superelevation - side friction - radius






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






5. Provide lateral guidance and support vehicles






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






7. 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






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






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






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






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. Average speed of drivers (SMS)






13. Rate per million entering vehicles






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






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






16. Grades - length






17. 11.2 fps^2






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






19. Speed without any impacts of delay (TMS)






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






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






22. 2.5






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






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






26. Infrastructure - vehicles - operators






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






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






29. Rate per hundred million vehicle miles of travel






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






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






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






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






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