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 curvature; PVC = PVI - g1^2(L)/2






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






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






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






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






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






7. Infrastructure - vehicles - operators






8. 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






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






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






11. Grades - length






12. Superelevation - side friction - radius






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






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






15. Average speed of drivers (SMS)






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






17. 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






18. Provide lateral guidance and support vehicles






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






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






21. 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






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






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






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






25. Rate per hundred million vehicle miles of travel






26. Mobility & Access






27. Rate per million entering vehicles






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






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






30. 2.5






31. Speed without any impacts of delay (TMS)






32. 11.2 fps^2






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






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