A friend's question:

Are there data about automobile accidents over the course of a year with daily increments and preferably with a large variety of filters like city, highway, etc?

California Polytechnic State University has a downloaded dataset on fatal accidents on the national highway system for the year 2007:

https://wiki.csc.calpoly.edu/datasets/wiki/HighwayAccidents

Data.Gov has a number of datasets on accident data by state: https://explore.data.gov/catalog/raw?tags=crash

The NHTSA has summary statistics for 2012 on a state by state basis here: http://www-nrd.nhtsa.dot.gov/departments/nrd-30/ncsa/STSI/USA%20WEB%20REPORT.HTM

The Insurance Institute for Highway Safety has accident/safety ratings per make/model/year, but you will have to scrap it off their site: http://www.iihs.org/iihs/ratings

Some of the city level open data portals also publish traffic accident datasets:

Denver: http://data.opencolorado.org/dataset/city-and-county-of-denver-traffic-accidents
Seattle: https://data.seattle.gov/Public-Safety/Traffic-Accidents/7ayk-pspk

The UK data.gov publishes accident/road safety datasets from 1979 to present here: http://data.gov.uk/dataset/road-accidents-safety-data

I put together an online catalog of sites covering traffic surveys and traffic accidents: http://www.opengeocode.org/opendata/traffic.php

    YO. if its cool, take my answer and add it to yours...i don't care about points...i want a compiled list! plz, thx! – albert Mar 12 '14 at 0:51
  • @Albert, looks like a lot of good work. – Andrew - OpenGeoCode Mar 12 '14 at 1:23
  • Injury epidemiologist here. I don't see hsisinfo.org on this list - it's where I get the actual / individual crashes themselves, including locations. You'll need a data request. But it sounds like you want aggregate data, not individual crash records. Still, wanted to add this to the answer for future searchers. – Mike Dolan Fliss Nov 1 at 18:37

not sure if my list is better (or worse), because i think it has alot to do with andrew's question about national/state levels. if andrew says its cool, i'll just have him update his answer with these links:

    np. share and share alike. its all about openness here – albert May 21 '14 at 14:21

Not sure if you need something for the entire nation, but a lot of localities publish versions of this kind of data.

Two examples: http://www.state.nj.us/transportation/refdata/accident/rawdata01-03.shtm http://nypd.openscrape.com/#/

Good luck!

If you want point-level data on crashes (but only for select states), I recommend submitting a data use request to the folks at the Highway Safety Information System (https://www.hsisinfo.org/) . I use that data to do small area research in NC.
