How we measure it
Curvature is the total change of direction along the road, in degrees for every mile, measured on the route line every 100 metres. Gentle drift under 3 degrees is ignored, so a long sweeping bend counts for less than a run of tight ones. On our routes they run from 6 on the E19 to 701 on the SP638.
Fuel counts stations within 1 km of the line on its longest stretch on our routes (19 miles), from OpenStreetMap. There are 5 on that stretch.
