The twistier the road, the more time spent turning. What I eventually came up with is a process of calculating the radius of curvature at every segment of every road and then adding up the length of the most curvy segments to get a total distance spent turning. Unfortunately all of these methods had situations that confused the algorithms (such as circular roads) or didn’t distinguish between fun curves and boring broad changes of direction that would only be exciting at far beyond the speed limit. I can get the raw data from the Open Street Map for the path of every road, but how to determine which ones are the most twisty? At the beginning I tried a strategies such as calculating the ratio of distance traveled on a road versus the distance between the start and end points. I’ve known this data was available for a long time, but it was only last week I realized that it would be possible to search through the coordinates that make up road-paths to analyze their geometry rather than just their position.

In some parts of the world the Open Street Map has better coverage than any commercial providers in the US the original data was imported from the public domain USGS TIGER data set and has then been expanded and improved by the community. While most of these systems use proprietary data sets, a service called Open Street Map (OSM) is a community driven project that anyone can add and edit - a Wikipedia for cartographic data.

What I realized I needed was a way to highlight just the most curvy roads so that I would know where to explore next.įor those less familiar with the intersection of cartography and software, the electronic mapping systems of the world (your Garmin/TomTom GPS, Google Earth, MapQuest, etc) have sequences of thousands of coordinates that linked together define the paths of roads across the surface of the earth. Atlases and electronic maps like Google Earth allow you to zoom in, but then there is the problem of finding the gems in the sea of data. While I’ve had some good successes in locating roads by map (such as Tracy Road), one of the shortcomings of a map is the tight curves you can really lean into tend to be below the resolution for many maps. While I’ve had great times on dirt roads through farmland and wide open highways, there just isn’t anything that compares to the thrill of leaning through the corners on a winding road. In the process of taking up motorcycling this summer I also gained an additional hobby: scouring maps and travel guides to find the roads that would be most fun to ride. Update October, 2013: Google Earth KML files generated by curvature.py are now available covering the entire world. Update November, 2016: New dedicated Curvature site. Update October, 2020: Curvature is now available as an in-browser map.
