The latest article on inclusive travel by Bob McKercher and Simon Darcy presents a systematic framework of the range of barriers affecting the ability of people with disability to travel. It is classified into a four tier framework from generic to specific. Below is an excerpt from the abstract explaining more about the four tier framework:
Previous studies tended to aggregate barriers into a single group … The failure to recognise the complex, yet subtle interplay between tourism and different types of barriers results in the tendency to see people with disabilities as a homogeneous group where a one size fits all solution applies. In reality, they are a heterogeneous cohort who face the same types of barriers as everyone, some barriers that are common to all people with disabilities, those that are unique to each disability dimension and specific impairment effects that are individualistic.
The full title of the article is “Re-conceptualizing barriers to travel by people with disabilities”, and is available from Science Direct, or directly from Simon Darcy on Research Gate. Published in Tourism Management Perspectives.
