Ruth Traffic Simulator - Datasets and Configurations for ACE / Evkit Benchmark

This repository contains the input datasets and supporting configuration files used in the evaluation of ACE (Asynchronous Communication and Execution) for scalable alternative route computation in traffic simulation, presented at SC25. Two scenarios are included: Prague (2.6M routes, compact urban network): shorter alternative routes with smaller graph size. Central Bohemia (25M routes, large mixed urban–rural network): longer alternatives with larger graph size. The files include: Origin–Destination (OD) matrices in CSV and serialized formats. Road network representations (GraphML, HDF5, Parquet). Configuration files (config.json). Conversion and test scripts (.py, .sh). OSM→HDF5 mapping: Central Bohemia Region/osm_to_hdf5_id.pkl maps OSM element IDs to the internal HDF5 map IDs to avoid the need to rebuild the map from GraphML. In the Prague folder the mapped IDs are already embedded (stored directly in the .pkl/.parquet), so there is no separate mapping step. These datasets allow reproducibility of the experiments comparing ACE and Evkit, covering computation time, startup overhead, and scaling behavior on the Karolina supercomputer.
