It's not often we get to see in such a stark way how dangerous our roads are. Luckily, ITO World, a UK transportation information firm, has done it for us, mapping every road fatality in the US from 2001-2009.

Zooming in to Marin, there are a few patterns. I count 27 deaths along Highway 101 in the county, with the worst part being right at the border, and 2 deaths on 580. On surface streets, I have:

14 deaths in Novato, including a 9-year-old pedestrian girl on San Marin Drive in 2009
10 deaths in San Rafael, including an 81-year-old pedestrian woman on 3rd Street in 2007
3 deaths in San Anselmo
1 death in Ross, a pedestrian
1 death in Larkspur, a 53-year-old cyclist man near the ferry building in 2003
1 death in Corte Madera
2 deaths in Tiburon
1 death in Sausalito
2 deaths in Mill Valley, both motorcyclists
25 deaths in West Marin

Over 9 years, 89 people have died on the roads of Marin. Most were in vehicles or motorcycles, but there were two bicyclists and a number of pedestrians that were killed. We're doing better than a lot of places, but it serves as a fresh reminder that roads are far more dangerous than we often remember. What do you see in this map?
