This is a statistical calculation of the average daily number of vehicles on a segment of roadway. In 2009, MDOT's surveys found that the highest AADT along the trunkline was 26,141 vehicles daily on the westernmost section near the US 23 interchange while the lowest counts were along the north–south section of Ecorse Road at 8,926 vehicles.[6] The section of M-17 from US 23 to the western junctions with Bus.
