This filtered view joins the refrigerated truck rate and volume data to calculate a weighted average rate per mile (rpm). Quarterly average rates are weighted by regional volume shares in that quarter. Mileage categories are: a) local–500 miles and less, b) short distance–between 501 and 1,500 miles, c) medium distance–between 1,501 and 2,500 miles, and d) long distance–greater than 2,500 miles.
