Martin Heng's biggest concern when he's travelling overseas is making sure his wheelchair is not a pile of unusable metal by the time he reaches the other end.

"One of the main concerns for anybody in a wheelchair is worrying if your wheelchair will make it in one piece to the other end of your journey," he said.

"That is your sole means of mobility when you get to your destination."

Mr Heng became a quadriplegic after being hit by a car while he was cycling, breaking his neck, seven years ago.

The keen traveller didn't want to stop visiting places around the world.

He is now working to make travelling easier for disabled people and said able-bodied people take many aspects of it for granted.

"It's about equality of access for all members of society, whether they're people with a disability, or parents with strollers, or older people with walkers, or indeed people with heavy luggage or delivering goods," he said.

"Good access benefits everybody."

A new study by global travel organisation Amadeus has assessed how to improve accessibility problems around the world.

It has found wheelchair access at train stations and on flights are among the biggest barriers for disabled people who are travelling.

"They should be careful with the way they handle wheelchairs. Five of mine have been broken during a flight," one person told the study.

The research also found the most reported problem for disabled travellers has been a lack of information about accessibility.

"It's not just incomplete information, it's inaccurate often … finding accurate and relevant information in order to plan a journey is paramount," Mr Heng said.

Mr Heng said Barcelona and Singapore were the best travel destinations for disabled people.

"Singapore is possibly the most accessible city that I've ever visited … also Barcelona, the BART system in San Francisco," he said.

"In Australia and in much of Europe, you have to go to a railway platform and then wait for a driver or a member of staff to put a ramp up or something, and while that's ok that's not equality of access."
