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






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






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






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






5. Rate per hundred million vehicle miles of travel






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






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






8. Grades - length






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






10. 11.2 fps^2






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






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






13. 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






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






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






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






17. Mobility & Access






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






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






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






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






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






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






24. Provide lateral guidance and support vehicles






25. 2.5






26. 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






27. Infrastructure - vehicles - operators






28. Rate per million entering vehicles






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






30. Speed without any impacts of delay (TMS)






31. Average speed of drivers (SMS)






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






33. Superelevation - side friction - radius






34. 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
