 If the queue jump lane is designated as bus-only, then standard traffic signal detection such as loop detectors or video detection can be used.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.
