MilleMiglia is a C++ library that produces synthetic middle‑mile logistics networks with up to 10,000 nodes and 100,000 edges. It runs on any POSIX system with a C++17 compiler and requires only standard STL, no external dependencies. The generator outputs JSON‑like files that match the format used by existing VRP solvers, effectively replacing proprietary datasets that are normally inaccessible.
It is useful for researchers and practitioners who need realistic benchmark instances without accessing commercial data. However, it abstracts away real‑world constraints such as traffic variability and carrier contracts, so it may not capture all operational nuances. If you need fine‑grained vehicle scheduling or integration with live routing engines, this tool alone won't suffice.
