Queue jump

A queue jump is a type of roadway geometry used to provide preference to buses at intersections, often found in bus rapid transit systems.

The intent of the lane is to allow the higher-capacity vehicles to cut to the front of the queue, reducing the delay caused by the signal and improving the operational efficiency of the transit system.

The length of the queue jump lane needs to be long enough to provide a meaningful time savings.

If there is a limited amount of other traffic in the lane, then two or more loop detectors can be used and configured with AND logic such that only a long vehicle will actuate the advance phase.

If the queue jump lane is shared with a higher volume of other traffic, a more high-tech detection scheme may be needed such as Opticom or RFID.
