Road casualty (RTA) mapping for the USA coming later this week

We are getting ready to launch an online map showing fatalities from Road Traffic Accidents in the USA over a 10 year period next week in advance of Thanksgiving. In the mean time here are a few screen grabs.

The first image is for Manhattan Island (New York) and shows that most fatalities are of pedestrian (dark blue background with lighter figure). The number of Cyclists (dark green background with lighter figure), motorcyclists (orange with darker figure) and vehicle occupants (purple with a darker figure) is also significant. Pedestrians are generally in their 30s-50s, motocyclists are more likely to be in the 20s and 30s. The youngest pedestrian death that I can see is of a 3 years old boy and the oldest is of a 99 man - click to view image at full size.

And here is the pattern in Washington DC where the percentage of vehicle occupants is higher; the spread of ages seems pretty wide was well.

This map shows the Silicon Valley are with a cluster of pedestrian fatalities around Stanford University and a string of vehicle fatalities on highway 101.

The overview for Washington State (Seattle is on the right) invites the user to zoom in, but even at this scale it is possibly to see how the crashes are distributed across the territory and the distribution by mode.

By contrast, this overview map showing the area around near Rapid City, South Dakota shows that nearly all the of fatalities are of motorcylists in an area that is very popular touring area motorcyclists btw:

In you want to have an idea what the service will look like when it comes then do try our UK Road Casualty mapping service.

We are keen to add details for every country that has suitable data available. If you can recommend any good sources of such data then please add a reference in a comment at the end of this blog or email us.
