Evaluation of Transit Signal Priority Options for Future 5600 W Bus Rapid Transit Line in West Valley City, Utah (12-4166)

This paper presents an analysis of different Transit Signal Priority (TSP) for a future Bus Rapid Transit (BRT) corridor in West Valley City, UT. The goal is to find the optimal TSP strategy for estimated and planned traffic and transit operations. The study uses VISSIM microsimulation software in combination with ASC/3 Software-in-the-Loop (SIL) simulation. Four different models were used in the analysis: No TSP, TSP, TSP with phase rotation and Custom TSP. The results show that TSP with phase rotation and Custom TSP can both be considered for implementation. TSP with phase rotation brings significant benefits for BRT, with minimum impacts on vehicular traffic. Custom TSP brings major benefits for BRT in terms of travel times, delays and stops. However, this strategy has more impacts on vehicular traffic. Custom TSP is an advanced strategy that still needs examination and improvement. The study provides a set of instructions on how the described strategies can be implemented in the field traffic controllers.
