Google has announced an update to its Maps service which will be able to more intelligently guide users using public transport.

The update now has access to the time and route of every train, bus, tram and ferry in the UK, claims Google. That's nearly 17,000 different route possibilities.

The Google Maps app, which is available on Android, iOS and desktop offers public transport guidance including information from Traveline and National Express.

David Tattersall, product manager for public transport in Google Maps, says: "You'll now know when the next trip is departing, how many stops and how far your walk is between each station. You can also pick your preferred method of travel and whether you'd rather walk less or make fewer transfers, so you can compare and choose the best option for you."

With Apple Maps expected to receive an update on iOS 8 soon this improved Google Maps is well timed.
