Pelican crossings are traffic light controlled and will only change if someone presses the button, which is located on the side of the traffic light pole. Where as normal traffic lights will change on an automatic sequence when the button is pressed, the Pelican crossing traffic lights will change to allow Pedestrians to cross safely. The name derives from PEdestrian LIght CONtrolled with the o changed to an a in reference to the bird.
Sequence of Lights for a Pelican Crossing.
The sequence of lights for a pelican crossing would be as follows: Red, Flashing Amber Green. Steady Amber Red. All of the different coloured lights appear on their own.The flashing amber light keeps the traffic flowing. If the crossing is clear you may proceed. However, if there are pedestrians still on the crossing, you must still give way to them. Unlike a traffic light, which would have the following sequence. Normal Traffic Light Sequence is; Red, Red and Steady Amber, Green, Steady Amber, Red .
Approaching a Pelican Crossing
Let's imagine we're approaching a pelican crossing and the lights go through their sequence from Green up to Red. Green, Steady amber, Red.
Use your MSM routine in good time and slow down to let the pedestrians cross safely to the other side of the road. Remembering not to "rev" your engine while you wait for them to cross, as this could cause the pedestrians to hurry across the road. The crossing is clear and the flashing amber light appears, you may proceed. However, ensure that the pedestrian doesn't change their mind and double back across the crossing! When approaching a pelican crossing and the Pelican has just changed from Red to the flashing amber, keep checking to see that the crossing is clear before committing your self to driving through the crossing. Pedestrians such as the young, elderly or the infirm may take longer to cross the road and may still be on the crossing even when the lights have changed to Green. Like the Zebra Crossing, the Pelican Crossing has two variations:
The Straight Crossing.
The Staggered Crossing.
The Straight Crossing
This type of Pelican crossing incorporates a central island, but either side of the crossing are not in line. This type of Pelican Crossing would be classed as being two separate crossings. As the lights on either side of the road will work independently of each other.
Puffin Crossings
The Puffin crossing is another variation on the Toucan crossing in that it incorporates an electronic scanner to monitor the crossing.
Zig Zag Lines Zig zag lines are placed before and after the crossing to protect the crossing. See the Zebra crossing tutorial for the rules about Zig Zag lines.
Zig zag lines are used on the following crossings:
Toucan-Pelican-Puffin.
The Toucan crossing is a crossing that allows pedestrians and cyclists to use the crossing at the same time.

As with the other crossings, the Toucan crossing incorporates zig zag lines to protect the crossing.

Let's suppose someone presses the button and then walks away without using the crossing, the scanner would detect that no one is standing next to the crossing and therefore will keep the traffic lights on Green and this helps to keep the traffic flowing.
Another advantage of using the electronic scanner is that unlike a Pelican crossing, the Toucan crossing will keep the lights on Red if someone is still on the crossing, which gives the pedestrian plenty of time to cross the road without the worry of the lights suddenly changing. This is especially useful to the elderly, the young and the infirm. Whereas a pelican crossing has a set time for the lights to stay on Red. Once the time limit is up the traffic lights will work their way down to Green.
