Sam,
Thanks for pushing a street safety agenda...saving lives should come first for all of us.
I think its critical to point out at the get go that reducing speed is key to increased safety. Without speed reduction...achieved with both posted speed and design changes (narrower streets)...painted crosswalks could be counter productive.
I noted up at NE Fremont and 42nd that for half a block Fremont widens out considerably...why not angled parking in front of Beaumont Market? or just create a plaza there with cobblestones and some refuge islands with trees that clearly mark the beginning of a different kind of street...one with schools, lots of businesses and their customers, etc. where cars are welcome, but at a much slower pace.
Enforcement is out of your hands, but its seems that limited traffic enforcement resources should not be used to cite bicyclists who fail to come to a complete stop (and are mainly a risk to themselves); rather we must focus on motor vehicle speeds in school zones and commercial districts. Perhaps with double the fine of current law...this is serious business.
Educating motorists via somekind of campaign could be effective..."Yield...its the law, and its cool", but also, I think pedestrians need to be educated to be more assertive...a tricky balance of being safe while also insisting that vehicles yield. In Rome, Italy I remember watching folks cross a busy street without breaking stride, like they owned it, while I stood cowed at the curb.
But where your leadership is critical is when it comes time to decide between vehicle through-put and ped safety... and the latter needs to trump the former or we are wasting our time.
