The puffin crossing differs from a pelican crossing in several aspects.
The red/green man indicator is positioned above the 'WAIT' indicator adjacent to where pedestrians stand when waiting to cross. This enables pedestrians to see oncoming traffic and the red/green man indicator at the same time.
When the green man symbol illuminates it is safe to cross the road. This is sometimes accompanied by an audible signal. When the audible signal is not permitted for use, a tactile cone is provided under the push button unit. This rotates when the green man symbol is lit.
The crossings are fitted with above ground detectors that increase their efficiency by:
1. Cancelling the demand if the pedestrian moves away from the crossing
2. Adjusting the time available for pedestrians to cross the road
This enables the crossing to respond to the on ground traffic and pedestrian situation, enhancing safety and minimising delay.
