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. 2.5






2. Provide lateral guidance and support vehicles






3. Rate per million entering vehicles






4. Average speed of drivers (SMS)






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






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






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






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






9. Infrastructure - vehicles - operators






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






11. 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






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






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






14. Speed without any impacts of delay (TMS)






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






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






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






18. Superelevation - side friction - radius






19. 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






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






21. 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






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






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






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






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






26. Mobility & Access






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






28. Grades - length






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






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






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






32. Rate per hundred million vehicle miles of travel






33. 11.2 fps^2






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