This page lists all licenses of code SUMO depends on directly for compiling. There may be secondary references (like the C++ standard library or a particular OpenGL implementation) which are not mentioned here except for the cases where we deliver binaries for that code.

Code in the repository

All the code which can be found under <SUMO>/src and <SUMO>/tools except for <SUMO>/src/foreign and <SUMO>/tools/contributed is since 03.10.2017 (revision 26300) licensed under EPL V2. All earlier versions were licensed under GPL V3+. The code in <SUMO>/src/foreign and <SUMO>/tools/contributed should have separate license files but we strive to list them here as well:
