摘要

In this 2011 Past Presidents' Award paper the author modeled transit signal priority (TSP) and queue jumpers at six signalized intersections for the Livermore Amador Valley Transit Authority's Bus Rapid Transit (BRT) system in the City of Pleasanton, California. Vehicle actuated programming to model green extension, early green, and queue jumpers along the 2-mile-long corridor were used. Two VIS-SIM models were developed for the alternative analysis: one with TSP operation and right-turn queue jumpers only and the other with TSP operation and both right-turn and left-turn queue jumpers. A maximum of 10 percent of the cycle length for extended green/early green to avoid deteriorating level of service for the rest of the traffic was used. It was found that TSP and queue jumpers helped reduce bus travel time by 30 percent without adversely affecting automobile traffic in the corridor. TSP and queue jumpers are most beneficial when congestion levels are higher. Intersections with higher v/c ratios for the corresponding through movement offer higher travel time savings for the bus when the intersection has TSP or queue jumpers. The VISSIM models will serve as planning took to further understand TSP operation and queue jumpers in a BRT system.
