Question

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, the five minute peak hour factor (round off to $2$ decimal places) is _____

• A. 0.52

Answer 1

The correct option is A 0.52
Five minute peak hour factor

$=\frac{flowinpeakhour}{\frac{60}{5}\times peakflowduring5minute}$

$PH{F}_5=\frac{V_{av}^{60}}{\frac{60}{5}\times V_{av}^5}=\frac{1000}{12\times 160}=0.52$
