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






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






3. 11.2 fps^2






4. Rate per hundred million vehicle miles of travel






5. 2.5






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






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






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. Grades - length






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






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






12. 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






13. 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






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






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






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






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






18. Rate per million entering vehicles






19. Speed without any impacts of delay (TMS)






20. Average speed of drivers (SMS)






21. Infrastructure - vehicles - operators






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






23. Superelevation - side friction - radius






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






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






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






27. Mobility & Access






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






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






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






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






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






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






34. Provide lateral guidance and support vehicles
