Hi,

you might find this interesting: we’ve recently released a project about the limited accessibility of public transport (subway + commuter trains) in New York, London and Hamburg. The results are maps with an interactive slider that let you explore how thinned out the transportation network get’s when you’re handicapped e.g.

and here all the information about the project: http://mappable.info/blog/2014/2/8/accessibility

Transit Maps says:

The depiction of physical accessibility on transit maps of is something I’ve touched on before – see this great 2007 map of the London Underground with all the inaccessible stations removed (Nov. 2011, 5 stars) – but this is a fantastic and intuitive way to show the difference between all stations and only the accessible ones.

You should definitely click through to the full blog entry about this project and see the full interactive maps that have been created for New York, Hamburg and London. If you’ve been inspired, they also give ideas and instructions on how to create a similar map for the transit in your city.
