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.
