Tools for improving road data

We have lots of Free software tools and open projects that could be utilized to help improve road networks.

Here are some of the most interesting ones:

https://labs.strava.com/slide/ - Strava's "Slide is based on the principles of Mathematical optimization. A coarse input line is iteratively refined to optimize its alignment with the GPS heat data. The result is a smooth, properly sampled path representing the true path of travel."

https://github.com/sharedstreets/sharedstreets-builder - "SharedStreets data standards are a way to uniquely identify any street in the world. SharedStreets makes maps connectable, and allows quick porting of data between different street representations, whether data linked to OpenStreetMap, a city-managed GIS system, or a commercial basemap."
