GPS-based transit signal priority (TSP) has advantages in providing flexible and conditional signal priority to transit vehicles. This study compared the effectiveness of different combinations of operational patterns and TSP strategies and assessed their impacts on side-street traffic operations. Micro-simulation analytical tools were applied to two testbeds of Utah Transit Authority’s Bus Route 33 and bus rapid transit (BRT) Line 35 MAX. Eight scenarios were created for Route 33 that included the existing conditions and combinations of regular/BRT operational patterns with traditional TSP, GPS-based TSP, conditional TSP implementations. Three scenarios were created for 35 MAX, also considering the existing traditional TSP condition, GPS-based TSP, and conditional TSP implementations. Results confirmed similar operational effectiveness of GPS-based TSP when compared to traditional TSP. Conditional TSP had smaller impacts on side-street traffic while providing transit vehicles considerable amounts of delay reduction and travel time saving.
