According to this map the world's straightest roads are inward the American Mid-West together with the Canadian prairies. How Straight or Bendy are the World's Roads is a Leaflet powered map showing the straightness of the world's roads (or at to the lowest degree all the roads that bring thence far been added to OpenStreetMap).
Each route on OpenStreetMap has been given a 'bendyness ratio', which was calculated past times dividing its length of the route past times the demand trouble departure betwixt its halt points. The map is divided into equal sized squares. Each foursquare on the map is thence colored past times the straightness of all the roads inward that square.
North America seems to bring the world's straightest roads. Holland together with northern Federal Republic of Federal Republic of Germany every mo good appear to prefer their roads to move of the demand variety.
