osm-legal-default-speeds | Infer default legal speed limits from OpenStreetMap tags

osm-legal-default-speeds is a Kotlin library. osm-legal-default-speeds has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Kotlin multiplatform library that provides information about legal default speed limits. Runs on JVM, native and JavaScript. It can be used by data consumers such as router software to fill the gaps in OpenStreetMap data, i.e. when explicit maxspeed tagging is missing because there is no explicit sign or because it hasn't been tagged yet. Additionally, it can be used to supplement the legal speed limits for other vehicle types (buses, goods vehicles, motorcycles, ...), as these can be assumed to never be tagged unless explicitly signed. It uses the data from the Default speed limits page from the OpenStreetMap wiki as input. In the parser/ subdirectory, there is a parser written in Python that generates a JSON from the data in the aforementioned wiki page. The data from this JSON can be consumed by the library (found in the library/ subdirectory).
