IDENTIFYING LOCATIONS FOR BUS NUB INSTALLATION ON URBAN ROADWAYS

Despite the recognized benefits of bus nubs in some locations, the safety and effectiveness of bus nubs are questioned in dense urban locations where heavy vehicular volumes and long bus dwell times may result in increased congestion if a bus nub is installed. In many urban areas with heavy bus and vehicular volumes, curbside parking is eliminated upstream of a bus stop to allow buses an easier access to the bus stop. Installing a bus nub at these locations would decrease roadway capacity resulting in increased delays to all vehicles on the road including buses. This paper describes the development of criteria for identifying locations where bus nubs would be appropriate for installation. The criteria are intended to ensure that the nubs will be effective in improving operations for buses, without significantly affecting roadway operations or causing safety concerns to pedestrians and bus patrons. The research attempts to quantify trade-offs between improved bus operations and possible increases in roadway congestion due to bus nubs.
