Electronic queuing systems for taxis have been brought in at the arrival hall to reduce queues during extreme weather, the Airport Authority said on Thursday.

Steven Yiu, the executive director of airport operations, said the system was introduced in March this year after people had to queue for hours last year during a typhoon.

He said a mobile phone notification or the airport's information board would now tell passengers when their taxi was ready.

"We tried to avoid a long queuing for prolonged-waiting passengers. For example, if the typhoon lasts three to four hours, we don't let the passengers keep queuing for long periods of time, so we give them some sort of queuing number so they can stay in the restaurant and also rest until being called forward to the taxi station," he said.

"We created a resting area, actually it is a large area with over 500 chairs, with Wifi [and a] charging facility. We will also distribute water, biscuits to them, and also some blankets as well."

He said the authority hopes to make passengers feel comfortable, especially when taxis and Airport Express trains can't operate under Typhoon Signal No 9.
