The issues facing “less cars” transpiration options are quite well know—old and poorly designed infrastructure. These are not only a problem for people with disabilities, they affect all of society. Universal design not guides solution it also informs us that the problems affect more than one segment of the population.
Why do minorities bike less is a great read as it connects the issue with the infrastructure deficits that are both cause and create the reduced usage. The moment to enhance biking options is the same struggle we have with walkable and usable streetscapes. Its also about the struggle to re-purpose existing streetscapes rather than just build new neighborhoods in gated communities. Reclaiming car centric urban areas, especially those that need community investment, is a critical task for transport activists.
