A Study of Applying Eco-Driving Speed Advisory on Transit Signal Priority
summary
A cooperative system called ATSP-C system integrates transit signal priority with an eco‑driving speed advisory under Connected Vehicle assumptions, implemented in SUMO on a real Tainan electric bus route and driven by an intersection passing‑probability test and signal phasing from RSU→OBU. The scheduler tries red truncation or green extension (ymax tested at 22 s vs 10 s), the advisory searches speeds in 0.7–1.1× speed range to maximize passing probability, and results show up to 33% delay reduction (VC 0.5) and ~1–1.5% energy savings while assuming full compliance.
