Evaluation of Transit Signal Priority Strategies for Bus Rapid Transit Project on 3500 South Street in Salt Lake County, UT

Summary Information

This research evaluates bus rapid transit (BRT) implementation along 3500 South Street, a major arterial road in West Valley City, Utah, through microsimulation. This route is a major arterial and was the first BRT implementation in Utah.


The field of study consists of a segment of 3500 South Street with 13 signalized intersections along 3500 South, where traffic volumes are highest. Evaluations are based on a VISSIM simulation model, which was created for this sub-network, based on real traffic and transit data from the field for the period of 4pm to 6pm.


Transit signal priority (TSP) is estimated to reduce BRT travel times by 15 percent based on the results of the microsimulation. The results found that TSP has minor negative impact on side-street traffic and no impact or minor positive impact on main traffic.
