Zorluk: OrtaTraffic Lights and Signals

At a puffin pedestrian crossing, the traffic light sequence includes a flashing amber phase after the red light to allow drivers to proceed if no pedestrians remain on the crossing.

Cevap: Cevap

Cevap

False. Puffin crossings do not have a flashing amber phase; they transition from red to red and amber together, followed by green.
The statement is false because puffin crossings do not contain a flashing amber phase. Puffin (Pedestrian User-Friendly Intelligent) crossings use electronic detectors to monitor when pedestrians are crossing, varying the red light duration automatically. Consequently, they follow the standard UK traffic light sequence: steady red, followed by red and amber together, followed by green. Pelican crossings are the only light-controlled pedestrian crossings that display a flashing amber signal.

Adım Adım Çözüm

1
Identify the type of pedestrian crossing mentioned in the statement.
The statement specifies a puffin (Pedestrian User-Friendly Intelligent) crossing.
Different UK pedestrian crossing types operate with distinct signal sequences.
2
Determine the legal light sequence for a puffin crossing under the UK Highway Code.
Puffin crossings utilize infrared and pressure sensors and follow the standard four-phase traffic light sequence: Red, Red and Amber together, Green, Steady Amber, and Red.
A flashing amber phase is exclusive to pelican crossings and does not appear on puffin crossings.
3
Evaluate the statement against the determined sequence.
The claim that puffin crossings feature a flashing amber phase is incorrect.
Because puffin crossings manage clearance times via sensors rather than a flashing amber give-way phase, the statement is false.

Anahtar Kavram
