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






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






3. 2.5






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






5. Grades - length






6. 11.2 fps^2






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






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






9. Superelevation - side friction - radius






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






11. Rate per hundred million vehicle miles of travel






12. Rate per million entering vehicles






13. Provide lateral guidance and support vehicles






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






15. 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






16. Infrastructure - vehicles - operators






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






18. 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






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






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






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






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






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






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






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






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






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






28. Mobility & Access






29. 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






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






31. Average speed of drivers (SMS)






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






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






34. Speed without any impacts of delay (TMS)
