Disabled travellers often pay more for public transport than able-bodied passengers and suffer a worse service, according to a new report.
More than 100 mystery commuters recorded their experiences as part of a three-month undercover investigation organised by the Muscular Dystrophy Campaign.
They were unable to get on buses on a third of all journeys and found half of trains lacked basic disabled facilities.
A separate Department for Transport survey from 2006/07 found 42% of buses do not have low-floor wheelchair access and some travellers whose experiences feature in the new report said they could wait several hours for a bus with a working ramp to come along.
The report, called End of the Line, states disabled travellers often pay more for transport.
A Disabled Adult's Railcard allows a passenger to travel from London to Manchester for £35.65. The same journey on a coach, which are often not accessible to disabled passengers, costs £13.20.
Jessica Berry, 19, who has limb girdle muscular dystrophy, said: "Most people find it easy to get around and be independent, but when you are disabled, simple tasks like travelling spontaneously can be extremely difficult.
"It's incredible that transport providers think the level of service they currently provide for disabled commuters is good enough. The End of the Line report shows there is still a long way to go before the transport system in the UK really is accessible."
A spokesman for the Equality and Human Rights Commission said: "Although the Disability Discrimination Act started to come into force in December 2006, many disabled people still not do experience equal access to transport, leisure facilities and education."
