CDTA uses queue jump lanes to help BusPlus BRT buses travel through congested intersections before regular traffic. A queue jump lane is a transit treatment that includes dedicated bus only lanes or shares bus only right turns and a special signal. CDTA has installed 13 queue jumpers or special bus signals through its three BRT corridors across the Capital Region. The new BusPlus Purple Line BRT has three queue jumps and two special signal intersections. The queue jumps will be located at Partridge, Quail, and Lark/Library stations while the special signals will be located at Harriman West/ETEC and Brevator.
The queue jump signal is a specialized traffic system that grants priority to buses at intersections equipped with queue jump lanes. When activated, it provides buses with a brief, exclusive phase, allowing them to enter the intersection ahead of other vehicles, minimizing delays and increasing efficiency. This signal not only enhances the reliability of the BusPlus BRT lines, but also incentivizes more people to choose eco-friendly and time-efficient public transit options.
Queue jump lanes not only benefit CDTA customers by reducing travel times but also have positive impacts on overall traffic flow. As buses move more quickly through intersections, there's less congestion and reduced traffic-related emissions contributing to a greener environment.
The new BusPlus Purple Line service is set to begin in November 2023.
