The Transport Minister says bus routes in and out of Dublin need to be re-designed to help reduce the increasing delays traffic is causing for commuters.

There has been an increase in traffic of 30% since 2008 on some sections of the M50 in Dublin, with 120,000 cars a day passing through some parts of the motorway.

Over €1 billion has been spent in recent years on the Newland's Cross flyover, and the addition of a third lane on the M50.

However with commuters still facing increasing delays in getting to work, Minister Paschal Donohoe says other measures - including changing our bus routes - need to be considered.

He told Newstalk Breakfast:

"We have to look at how we can improve the capacity and the design of our public transport system to deal with that matter. What we can do in our bus network is an essential response back to that. We have to redesign bus routes that we have so that they are not going in and out of the city, but that they are going around the city aswell."

"So we can give people better options than getting into their car to complete journeys that are getting longer and longer."
