All US road casualties mapped

Via Steve Vance and David Levinson comes this disturbing and interesting web map.

369,629 people died on America’s roads between 2001 and 2009. Following its analysis of UK casualties last week, transport data mapping experts ITO World have taken the official data from the National Highway Traffic Safety Administration – and produced this powerful map using OpenStreetMap. You can zoom around the map using the controls on the left or search for your town using the box on the right – and the key is on the top left. Each dot represents a life.

Harrowing animation of NYC street intersection

“Bad interactions” as Kottke says, between peds, bikes and cars.

From the creator:

By summer 2010, the expansion of bike lanes in NYC exposed a clash of long-standing bad habits — such as pedestrians jaywalking, cyclists running red lights, and motorists plowing through crosswalks.

By focusing on one intersection as a case study, my video aims to show our interconnection and shared role in improving the safety and usability of our streets

The video is part of a larger campaign I created called ‘3-Way Street’. Please see blog.ronconcocacola.com for more details.

Minneapolis bicycle crash rates steadily decrease while bike commuting climbs

From the Star Tribune:

Recently crunched city data show the reported cyclist-motorist accident rate dropping as the number of bike commuters grows. For 2008, the most recent year for which complete data were available, the crash rate was one-quarter that of 10 years earlier. Moreover, a trend line shows a steady decrease in the crash rate even as the number of commuting cyclists more than doubled.

It would be interesting to see these crash rates for other cities, since we know mode share for bicycles is increasing in many parts of the metro.  I’m not sure if they parse them out as specifically as Minneapolis does.

The Strib also quotes Peter Jacobsen from the journal Injury Prevention, but leaves out a critical sentence (emphasis mine):

A motorist is less likely to collide with a person walking and bicycling if more people walk or bicycle. Policies that increase the numbers of people walking and bicycling appear to be an effective route to improving the safety of people walking and bicycling.

About a month ago, the Governors Highway Safety Association released a report that actually said “A focus on liveable communities…may increase walking and pedestrian vehicle conflicts”, although the discussion in the report actually seems to point more towards distracted pedestrians or pedestrians being forced to walk were poor or no facilities existed.
