Adding coach lanes to motorways would improve the popularity of this method of travel, it has been suggested.
According to the Campaign for Better Transport, dedicated routes would mean more people opting to travel by coach.
Such as move may be welcomed by those who regularly travel by road to holidays in Dorset.
Public transport campaigner at the body Cat Hobbs explained that it is important coaches are seen as a "quick option" if they are to become as popular as train and plane travel.
She explained that if people choose to travel by coach it is important that "they”re not stuck in traffic on the motorway when actually they should be speeding past in a coach lane."
Ms Hobbs welcomed the move by coach firms to advertise affordable fares but urged the government to think about how to make the method of transport even more attractive.
The Department for Transport has estimated that 4.9 billion journeys were made by bus and light railway in 2008-09.
