(Center Identification Number: 77939) Bus pullout bays are being installed increasingly on Florida’s roads as a safety factor and so that stopped buses do not impede traffic. In Florida, state law requires car drivers to yield to buses when a bus needs to reenter the roadway after a stop; yielding to the bus is important to helping it maintain a schedule. However, many drivers do not yield to the bus under these circumstances. University of South Florida researchers examined bus and driver behaviors at bus pullout bays in Hillsborough and Lee counties. The researchers had three objectives: identify critical design features and conditions that affect safety of buses merging into traffic from bus pullout bays; design a set of roadside treatments or traffic control devices to promote yield-to-bus (YTB) behavior at bus pullout bays; and recommend YTB traffic control devices for implementation and evaluation on state roads. First, a set of roadside sign alternatives are presented. In addition, bus bay in the participating transit agencies were measured to obtain performance measures for bus bay design features. It was found that the average acceleration distance was 70 ft. Field data collection was performanced to verify the before conditions at one of the potential test sites. Field data indicated that 33 percent of the merging maneuvers ended in a yield to the bus. Recommendations for the implementation of an advanced YTB roadside sign included using laser detectors and incorporating bys bay data in GIS transit inventory. Download the final report.
