I've been thinking about "right to the street" lately - the only laws protecting pedestrians in the street are marked crosswalk and sidewalk laws - but there are many residential neighborhoods where there are no marked crosswalks (or even sidewalks) - and many areas of Boston where the sidewalks are too narrow or impassable. from what I understand, if you don't have crosswalks within 300 feet, you can cross the street anywhere but motorists aren't legally required to yield to you (even if they see you). Boston and Cambridge have "shared streets" in their street design guidelines, but I'm not sure how pedestrians are protected in these places due to current law.
I know bike advocates have done a lot of work to protect cyclist's right to use public ways - but pedestrians don't have the same rights - it's pretty amazing that we have as high levels of walking around here considering that pedestrians are treated as second-class citizens on our public ways. I think what's most important right now is challenging this belief that the main purpose of streets and roads are only for moving vehicles - and that there can be some streets - particularly residential streets, where there is truly shared space. This is going to be the big challenge over the coming decades.
