Bicycle identification and cyclist notification at a traffic intersection includes determining a presence of a bicycle in a traffic detection zone and communicating an indicator that notifies the cyclist of both successful detection and that the presence has been communicated to the traffic system controller, so that a green light will be provided at the appropriate time for safe passage. Detectors at or near a roadway approach sense the presence or absence of a bicycle, and when a bicycle is detected, a signal communicated to the traffic signal controller for conversion to a suitable output signal that actuates notifications for cyclists.
