Reflection on the application of the Consolidated Framework for Implementation Research to a national policy to improve inclusion of people with disabilities.

People with disabilities face many barriers in the built environment impacting their mobility, health, and social participation. In the US, under the Americans with Disabilities Act (ADA), municipalities were required to develop and implement barrier-removal plans for pedestrian infrastructure, called ADA transition plans, but very few have done so. Many communities know they need a plan but do not know how to get it done because of a lack of understanding of the many different implementation considerations.
