Q2 (25 pts) A bridge crest vertical curve is used to join a +4 percent grade with a -3 percent grade at a section of a two lane highway. The roadway is flat before & after the bridge. Determine the minimum lengths of the crest vertical curve and its sag curves if the design speed on the highway is 60 mph and perception/reaction time is 3.5 sec. Use all criteria.
1. The Stopping Sight Distance is the distance needed for a complete stop. 2. The horizontal curve's radius should be increased when road friction & side-grade increase 3. The greater the difference between current speed and ending speed, the greater is the SSD. 4. Volume counts on roadways differ according to its class. 5. The comfort and appearance criteria do not apply to Crest Vertical Curves. 6. Home Interviews should not be used to find the Critical Routes on a Network. 7. If a horizontal curve's speed increases, the roadway superelevation must decrease for safet 8. The minimum distance to place a large sign or billboard from a curved road increases whe road curve's radius decreases. 9. DSD is always greater than PSD given the same maximum speed. 10. Signs and Markings information are gathered during the Intersection Studies. 11. Infrared Meters are used to measure densities. 12. Conflict Studies are different & not related to accidents studies. 13. Traffic Impacts Studies are used to measure the disbenefits of roads redesigns.
