Evaluating traffic performance of transit signal priority using SUMO simulation: A real-world case
summary
A SUMO-based evaluation of a V2X Tainan deployment models Bus No. 70 over 21 signalized intersections and nine electric buses, implementing a two-stage TSP (group progression + per-intersection isolated control) via Python–TraCI. Simulation yields a 16% average bus travel time reduction and 60% drop in waiting counts across 21 intersections; field surveys give MAPE 2.91% and 1.74% for pre-timed and TSP scenarios, validating the SUMO simulation calibration.
