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






3. Provide lateral guidance and support vehicles






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






5. Infrastructure - vehicles - operators






6. Speed without any impacts of delay (TMS)






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






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






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






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






11. 2.5






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






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






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






15. 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






16. Rate per hundred million vehicle miles of travel






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






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






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






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






21. 11.2 fps^2






22. 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






23. Superelevation - side friction - radius






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






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






26. Rate per million entering vehicles






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






28. Average speed of drivers (SMS)






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






30. Mobility & Access






31. Grades - length






32. 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






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






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