John Pockett, Director of CPT Cymru, the body representing the bus and coach industry said:
"The bus network, and the frequency of services for commuters to the main centres of employment in Wales are better now than ever.
"The problem is one of changing the culture where people get in their cars and drive, usually alone, to work, as any random check on, say the A470, A55 and M4 would show.
"Measures such as bus priority and effective parking enforcement are essential to encourage people out of their cars and onto public transport, which is a far more sustainable way of travelling.
"If you add the cost of fuel, parking charges and the stress of driving during the rush hour, public transport is, in fact, an attractive option to those main centres of employment."
