Preferential treatments for transit are needed for high-occupancy transit vehicles to improve theiroperations. However, these treatments are often not effective in saturated traffic conditions whentransit operates in mixed traffic. Additional Right-of-Way (ROW) for transit at intersections canbe achieved with Queue Jumpers. They allow buses to bypass the waiting queues by using queuejumper lanes and getting an early green signal. The goal of this paper is to evaluate individualand combined effects of Queue Jumpers and Transit Signal Priority (TSP) on performance of aBus Rapid Transit (BRT) system and vehicular traffic along 3500 S in West Valley City, Utah.Four VISSIM microsimulation models were developed for evaluation: the existing scenariowithout special treatments for transit (Base), the QJ scenario that introduced Queue Jumpersonly, the TSP scenario that implemented TSP only, and a combination of Queue Jumpers andTSP (QJ & TSP). The implementation of any transit strategy resulted in significantimprovements in BRT operations. The QJ & TSP scenario yielded highest benefits: 13-22%reduction in BRT travel times, better corridor progression, lower intersection delays and numberof stops, increased speed (22%), and better travel time reliability and headway adherence. Transittreatments did not affect private traffic along the corridor. These strategies, however, had certainimpacts on side streets. QJ & TSP scenario increased average delays for cross-street traffic by15%. However, with small improvements in QJ and TSP settings, the combination of the twostrategies can be most beneficial and highly desirable for implementation.
