About transportation, again, I haven't studied Laval's example, but it's a really good example of making transport accessible.
The piece I would stress from our project on isolation is the social aspects, and I think that echoes what you were trying to say. Transportation is not only related to medical issues and this sort of thing, but it allows older women, older people, to get out and about in the city. It creates ways of facilitating social engagement, inclusion in communities, countering the exclusion and isolation that can occur. It's the social aspect, providing support for programs that allow for social opportunities.
I think that is one such example. Allowing for public transportation, and making sure it's accessible and can work, allows people to make informed choices about being able to get out and about—go visit a friend, get their hair cut, and these sorts of things that help to break isolation.
