Nobody wants Marin to turn into a New York City - it's a great city but we like our quiet just fine thankyouverymuch - but that most pedestrian of places has become a laboratory for how to redesign streets with people in mind. From Redwood Boulevard to Alexander Avenue, there are myriad ways to actually improve the flow of traffic while giving space to those on foot or bike. Janette Sadik-Khan, chief of NYC's Department of Transportation, was the architect of so much of of this change and enshrined it in a planning guide for the rest of the country. At its most basic, her concern was for simplicity: simple intersections, simple crosswalks, simple interchanges, and so on. The Department of Transportation released a report, Making Streets Safer (PDF), detailing how to apply the principals it has pursued for 6 years.
Formed in the concrete canyons, these are principals we can apply to our much quieter county. Downtown Mill Valley, for example, is a tangle of streets, intersections, and crosswalks. You're never quite sure who can go next at the stop signs or where pedestrians are going to come from next or even where the parking actually is. The San Anselmo Hub, too, is a bit of a mess, with long delays at rush hour and a bus turn that relies on the goodness of drivers to navigate.
Streetfilms profiled the dramatic transformation New York underwent during Sadik-Khan's tenure. It is worth a few minutes of your day.
