SUMO needs plenty of RAM. You can reduce this somewhat by using a coarser intersection model. For that, just rebuild the network using the option --no-internal-links When using large route files, please make sure to load them with option --route-files (for incremental loading) rather than option --additional-files (loads all at once).
