• Description:
  The objective of this research is to introduce an adaptive real-time offset transitioning expansion to actuated controllers to improve coordination of traffic signals. This algorithm, the Purdue Real-time Offset Transitioning Algorithm for Coordinating Traffic Signals (PRO-TRACTS) is designed to mitigate the effect of early-return to-green problems experienced with coordinated actuated controllers and accounts for downstream vehicle queues that may impede vehicle progression. PRO-TRACTS fine-tunes the offsets at signalized intersections continuously to improve progression regardless of the offsets’ initial values. The algorithm presented in this report works with both the internal model of the CORSIM simulation package and actual NTCIP controllers.
