可以提高地铁换乘效率的新功能

For commuters in a hurry it can be hugely frustrating to find yourself queuing to get to the platform exit or to change lines after getting off a packed train.

对于行色匆匆的通勤者来说，在站台出口排队、从拥挤的车厢下车后还要排长队换乘着实让人沮丧泄气。

To ease these woes, public transport app Citymapper has released a new feature that offers advice on which part of the train to get on to shave time off your journey. The Boarding Strategy feature advises users whether they are better to get on the front, middle or back of their train in preparation for the next leg of their journey.

The new feature could also make journeys easier for visitors in unfamiliar cities by helping them make transfers between trains quickly and efficiently.

According to a post on Citymapper's blog: 'In peak hours this will knock minutes off your journey time. We have collected this data as much as we've been able to in all our cities.'

The service works when a user searches for a journey and also when using the Citymapper Go mode. A logo appears in the journey advice menu, suggesting which part of the train is best to get on. It also gives Citymapper a new edge when facing competition from search giant Google and Apple Maps.

However, some users have pointed out that it may lead to already packed carriages becoming even fuller if they are close to exits at popular stations. Plus, the app has still to provide advice that many commuters will be wanting, namely which carriage to get on to increase the chances of getting a seat.

Citymapper is available in 29 cities providing journey advice on trains, trams, buses, underground services and metro lines.
