I am an open software developer and OpenStreetMap enthusiast from Hamburg.

Former game and backend developer, I currently specialize in mobile app development.

You may know me as the author and maintainer of StreetComplete. I've been developing this app part-time since 2016 and since 2020 full-time alternating between being fueled by open source funds and on my own account.

Inferring default speed limits
Tobias Zwick

Coverage of maxspeed data in OpenStreetMap is very sketchy (about 12%). This situation is unlikely to change because the limits are often not signed explicitly. So, data consumers such as router software need to compensate huge holes in the data with more or less rough estimates based on other data.

This talk shall explore a method how to infer default speed limits for different vehicle and road types more precisely for each country.
