ATSUM: An Attlas-SUMO Middleware
summary
ATSUM is a middleware that automatically converts Attlas operational configs into SUMO networks, detectors, routes and executable signal programs, running deterministic pipeline steps for topology conversion, detector-based demand estimation, signal optimization and a real-time controller-in-the-loop loop. The system versions inputs/outputs for versioned reproducible runs, exposes a GUI, and was validated on a six‑intersection case with 3‑hour rush‑hour simulations where MaxBand produced better progression results than MultiBand in that instance, showing the pipeline reliably generates runnable SUMO experiments.
