The National Centre for Accessible Transport in the UK has collated a sizeable accessible transport resource collection. The aim is to see what is known and to reveal the gaps in knowledge. The collection contains guidelines, research reports, policy statements, and action plans. The material is mostly from the last ten years, some of which has appeared on this website before.

To get an idea of the publications here are some of the most recent ones:
The Resource Collection project is by the National Centre for Accessible Transport. It is a compilation of existing knowledge about accessible transport in the UK. A table lists the resources with the title and a link, a short summary, the type of resource and the date produced. There is a total of 630 documents some of which are specific for a particular disability type or group.
The National Centre for Accessible Transport (ncat), is an ‘evidence centre’. The purpose is to understand, document and analyse the current transport landscape. It does this by engaging with disabled people to hear about their experiences and transport professionals.
The About Us page has links to their latest projects. There is opportunity for members of the public to get involved by sharing ideas and finding solutions that work.
