Description: Lane width should be coded according to where the pavement/shoulder surface changes, or to the pavement lane striping (if the shoulder and pavement surface are the same). Where there is no delineation between the through-traffic lane and the shoulder or parking lane, or where there is no centerline, estimate a reasonable split between the actual width used by traffic and the shoulder or parking lane based on State/local design guides. When striping is placed inside the edge of the pavement (within approximately one foot) to keep traffic from breaking the pavement edge, ignore the striping and measure from the pavement edge to the center of a single centerline stripe. Or, if double centerline striping exists, measure to the center of the two stripes. If more than one lane exists, measure all lanes in the inventory direction and use the average value to the nearest foot. If lane widths vary over the extent of the sample section, use the predominant width(s) for measuring and reporting purposes.
