UCATSC: SUMO Dataset and Code for Uncertainty-Aware Constrained Traffic Signal Control Under Vision-Based Partial Observability

This record contains the reproducibility package for the UCATSC study on uncertainty-aware constrained traffic signal control under vision-based partial observability. The package includes SUMO isolated-intersection experiments, DQN-RL and safety-masked DQN outputs, targeted liveness and structured-uncertainty stress tests, a three-intersection arterial-corridor spillback extension, processed result tables, figures, trained model snapshots, route and network files, and controller scripts. A physical vision-testbed support folder is included with the Arduino Nano LED signal-head sketch and wiring/setup documentation. The package is intended to support review, reuse, and verification of the reported simulation results. The physical testbed material is a low-voltage laboratory prototype and is not intended for direct deployment on field traffic-signal hardware.
