To ensure that urban zigs and zags don’t masquerade as fun roads, I’ve recently added a filtering stage to Curvature that zeros-out the curvature rating for 30 meters (~100 feet) in both directions from each conflict point along the roadway. By zeroing out curves near these conflict zones Curvature can avoid suggesting roads that really aren’t very “fun”.
I’m happy to announce the launch of a new in-browser Curvature map with worldwide coverage. Now you can browse the map without any need to download KML files and open them in GoogleEarth. Planning trips on twisty roads has never been easier.
To assist new users, KML files will now include a legend indicating how to interpret the color scale and different line-weight given to roads: The legend will be added to KML files as they get regenerated over the next few weeks from the date of this post. This legend “overlay”…
Several years after releasing Curvature I finally got around to building a dedicated project website with information and instructions that are understandable by non-techies. Enjoy roadcurvature.com and spread the love of twisty roads!
