A simulation run of the full GB road model uses considerable RAM (up to ~80 or 120 GB).
This is largely due to holding pre-computed alternative route options for all origin-destination pairs in memory.
Could consider a file-based solution (leveldb, SQLite or similar?).
Though this would likely have some effect on simulation time, it would make the model much easier to run on any machine that's not specifically a "high-memory" VM/node.
