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






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






3. Average speed of drivers (SMS)






4. Rate per million entering vehicles






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






6. Superelevation - side friction - radius






7. Mobility & Access






8. 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






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






10. 11.2 fps^2






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






12. Speed without any impacts of delay (TMS)






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






14. Grades - length






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






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






17. Provide lateral guidance and support vehicles






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






19. 2.5






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






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






22. Rate per hundred million vehicle miles of travel






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






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






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






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






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






28. 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






29. Infrastructure - vehicles - operators






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






31. 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






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






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






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