Zorluk: OrtaPedestrians

You are stationary at a red light at a puffin crossing while an elderly pedestrian crosses slowly in front of you. What will happen to the traffic lights as the pedestrian continues walking across the carriageway?

  1. The red light will stay on until the pedestrian reaches the opposite pavement safely.Cevap
  2. B
    The lights will change to flashing amber, allowing you to proceed while looking strictly at the road directly ahead.
  3. C
    The lights will turn green after a fixed time, meaning you must flash your headlights to encourage the pedestrian to hurry.
  4. D
    The lights will cycle immediately to green, allowing you to move off without checking your blind spots.

Cevap

The red light will stay on until the pedestrian reaches the opposite pavement safely.
Puffin (Pedestrian User-Friendly Intelligent) crossings have infrared sensors mounted above the signal heads. These detect when pedestrians are crossing and dynamically extend the red light phase for vehicles until the pedestrian has safely reached the pavement.

Adım Adım Çözüm

1
Identify the type of pedestrian crossing specified in the scenario
The crossing is a puffin (Pedestrian User-Friendly Intelligent) crossing.
Different crossings operate under different light sequences and control mechanisms.
2
Apply Highway Code rules regarding puffin crossing sensor technology
Infrared or optical sensors detect the pedestrian on the carriageway and extend the red signal for vehicular traffic.
This ensures vulnerable pedestrians who take longer to cross can do so safely without traffic being released.

Anahtar Kavram

Puffin crossings use sensors to automatically extend the red light phase until pedestrians have safely crossed.
