Victorians are finally able to access public transport data using the Google Maps directions app on their phones and tablets.

The app had previously featured information on the best routes by road, foot and bicycle, but did not have any information on public transport.

That information has been available for in other states for some time, but only went live in Victoria on Wednesday.

Premier Daniel Andrews announced on Reddit last year that public transport timetable data would be released to Google.

He compared travel data in Sydney with Melbourne, and said his state was not good enough.

Public Transport Minister Jacinta Allan said there were difficulties making data from Public Transport Victoria (PTV) work with the Google Maps app.

"PTV first released the data for this type of application in April last year and it's already being used by other companies," she said.

"What has needed to be done with the case of Google... there needed to be some additional data requirements to meet the specifications of the Google app.

"It was about meeting the additional requirements that Google needed and that took a bit of time.

"But we're here now and Google Transit is now live and running."

She said the feature would make it easier for people to use public transport across Melbourne and Victoria, and choose whether road, tram, train or bus might be the best option.

However, the app would not include live updates on public transport timetables, such as cancellations and delays.

Ms Allan said commuters would have to make use of the PTV app.

'There is that information there and we are working on how that can be the next stage in the information that's provided through Google transit," she said.
