3. A crest vertical curve joins a +3% and -4% grade. Design speed is 75 mph. Length = 2184.0 ft. Station at VPI is 325+ 55.00, elevation at VPI = 260 feet. Find elevations and station for VPC (BVC) and VPT (EVC). 4. On a 0.5-mile highway segment, if the speeds of these 8 vehicles are measured as 55, 45, 40, 50, 60, 65, 70 and 65mph, respectively, what is time mean speed? What is space mean speed. 5. An observer located at point X counted 6 vehicles passing through this point during a period of 45 seconds. What is the hourly flow rate based on the observation? Good Lucky DDA 0 IN INEERI Engine
