I know the formula for calculating Space mean speed is pretty straight forward, but I am getting confused by the calculation shown in HCM.
If you look at page 7-3 in the end the SMS is supposed to be 38.298, I cannot understand how HCM has arrived at 25.5 mi/h.
I used nL/ (sum of travel times); n is the no. measurements, L is the distance. Can some one please review this for me.
Thanks.
