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 tangency; PVT = PVI + g2^2(L)/2






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






3. Grades - length






4. 11.2 fps^2






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






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






7. Superelevation - side friction - radius






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






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






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






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






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






13. 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






14. Average speed of drivers (SMS)






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






16. Speed without any impacts of delay (TMS)






17. Rate per million entering vehicles






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






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






20. 2.5






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






22. 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






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






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






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






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






27. Provide lateral guidance and support vehicles






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






29. Infrastructure - vehicles - operators






30. Mobility & Access






31. Rate per hundred million vehicle miles of travel






32. 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






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






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