- F1The equivalent hourly flow rate for an approach with 125 vehicles in the peak 15 minutes and PHF = 0.92 would be:QUESTION 12 60 10. 15-min Volumes 75 40 Lane Configurations Y Consider the left turn movement from main street. If the conflicting flow rate is 280 veh/hr, and the critical headway, adjusted for heavy vehicles and grade, is 4.2 seconds, and the follow-up time, adjusted for grade, is 2.29 seco nds, calculate the potential capacity, Cp,4 (veh/h). Provide your answer to the nearest integer. SRCP
- THE MAXIMUM NUMBER OF VEHICLES OBSERVED IN ANY FIVE-MINUTE PERIOD DURING THE PEAK HOUR IS 160. IF THE TOTAL FLOW IN THE PEAK HOUR IS 1000 VEHICLES, FIND THE FIVE-MINUTE PEAK HOUR FACTOR.14. Free-flow speed of vehicles on a road section is 88 km/h. Jammed density is 228 veh/km. Determine the traffic density on the road if traffic flow is at a maximum level. Also determine the possible maximum flow for the road section and the average speed of vehicles at that maximum traffic flow rate. (114 veh/km, 5016 veh/h, 44 km/h)Choose the correct option
- Problem 2: A Class III two-lane highway is on level terrain, has a measured free-flow speed of 45 mi/h, and has 100% no-passing zones. During the peak hour, the analysis direction flow rate is 150 veh/h, the opposing direction flow rate is 100 vehh, and the PHF = 0.95. There are 5% large trucks and 10% recreational vehicles. Determine the level of service.The rate of flow at a point in the expressway is 1/3veh/sec. Compute the space mean speed if the density is 25000 veh/m.Problem 23: A motorist traveling at 100 kph on an expressway intends to leave the expressway using an exit ramp with a maximum speed of 50 kph. At what point on the expressway should the motorist steps on her brakes in order to reduce her speed to the maximum allowable on the ramp just before entering the ramp? The section of the expressway has a downgrade of 3%. Acceleration is 3.5 m/sec?.
