In 2012, around 59 million Europeans (aged 15 and over) reported a disability with regards to mobility or transport. Disabled people have specific mobility problems depending on the cause of their impairment (e.g. reduced vision, hearing or movement, environmentally or psychologically challenged).

There is now wide recognition of the importance of issues such as access to transport and the impact that it can have on the quality of life and independence of disabled people. Yet, there is no general agreement nor clear understanding about most disabled population mobility habits. People with a disability are a very heterogeneous group with several different types of impairment, which inhibit their travel options in different ways and consequently their personal quality of life and independence.
