Extension and Validation of NEMA-Style Dual-Ring Controller in SUMO

on YouTube ↗16m

" summary

Adds a dual-ring NEMA controller into SUMO source, implements fully-actuated timing, phase fit, green transfer, latching detectors and TS2-style offsets, and validates against an Econolite SIL running real controller configs from a three-intersection Tuscaloosa corridor. Validation uses simulation replay and millions of seconds of randomized fuzz testing plus coordinated/free-mode comparisons; results show matching phase timing, no barrier-cross events, and fixes pushed into SUMO 1.13.0 with tests and docs.
