Question 6 (Peak Hour Factor): Given the traffic volume data provided below, answer the following questions: (1) Find the peak hour factor (PHF) for the hour of 4:00-5:00PM. (2) Find the peak hour factor (PHF) for the hour of 5:00-6:00PM. (3) Compare the two PHF values you got from part (1) and part (2). Which hour has a lower PHF value? What contributes to the lower value? (4) Based on your analysis, interpret the meaning of PHF. Time Interval 15-minute...

A traffic engineer collected the eight 15-minute traffic volume from 7:00 am-9:00 am. The eight 15-minute traffic counts are 150, 175, 200, 250, 260, 220, 190, and 160, respectively (7:00-9:00 am), what are the peak hour traffic volume and Peak Hour Factor (PHF)? What is the breaking distance (ft.) for a vehicle from an initial speed 55 mph to a final speed of 35 mph? Assume the coefficient of friction is 0.5 and 5% downgrade. A traffic engineer’s 10 minute...

Problem 1 (15vpts) A proposed highway has two tangents of bearings N 75° 54' 36" E and N 53° 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve to join these tangents, decides that the external ordinate is to be 78.00 ft. The Pl is at station 65+43.21. Determine: (a) The external angle of the curve (A) (b) The radius of the curve (d) The station of the PC (f) The...

I. A highway transportation agency is conducting a traffic count on an existing highway for the purpose of determine the directional design volume. An automatic traffic counter using a weigh-in-motion (WIM) equipment gave a total continuous one-year count of 4,372,096 axles. Manual classification studies at the count station indicated the following: Passenger cars = 3-axle trucks 4-axle trucks 5-axle trucks = 69% 21% 6% 4% (a) Calculate the existing average annual daily traffic (AADT) in vehicles per day....
