1- Calculate the PHF for a facility with an hourly flow rate of 5394 vehicles/hour and a peak 15-minute volume of 1450 vehicles. 2- What is the hourly flow rate on a facility with a PHF of 0.89 and a peak 15-minute volume of 927 vehicles? 3- The speed of 10 vehicles were measured as spot speeds at the midpoint of a 1.207 km section of roadway. Calculate the TMS and SMS for the vehicles, assuming each vehicle travelled the entire section of roadway at a uniform speed. The speeds collected were as follows: Vehicle 1 Speed (km/h) 85 2 90 3 91 4 88 5 84 6 86 7 85 8 89 9 84 10 85 4- Why TMS and SMS have different values? Do a parametric study for a general case with 3 vehicles.
