Augmenting with Ring-and-Barrier Structured Traffic Signal Controller Module
summary
Claims a working SUMO extension that models eight NEMA phases in a two-ring, two-barrier structure, plus a TraCI command to update timings in real time. Two approaches are implemented: a translator that converts NEMA timings into SUMO stage files (reliable for fixed-time control) and a new Ring-and-Barrier controller module added to SUMO source that supports actuated and coordinated actuated control. Validation uses simulation animation and logs and the module successfully reproduces generalized North American NEMA timing behavior.
