I am graduate student studying in GIS.

My project is related with traffic accidents, but I cannot find the traffic accident data online.

The scale could be a city or a state in US since I just started the project. I prefer bigger cities though, more accidents data will make the project more analyzable.

Is there any suggestion?

    What country? Police and insurance companies might have some data but they might not want to share it. – Michael Stimson Jun 23 '15 at 1:07

Your questions here should always provide details of your research so far into answering your own question, before telling us where you are now stuck. I recommend that you use the edit button to revise your question with much more detail. Firstly, I think we need to know what country you are looking for the data in. – PolyGeo Jun 23 '15 at 1:07
  • It should in US. I think about that, and the data I need is not necessary last version. It could be back to 2005. I am thinking pull form google map, I do not know how difficult it will be. – wangby0906 Jun 24 '15 at 18:05

    Can't find it? Really? Pick a city name and Google on that with 'traffic accident GIS data'. Or even leave the city name off. I see pages and pages of results, several of which lead directly to pages with shapefile download links. Denver for example. Or New York (city, state, and county). – Chris W Jun 28 '15 at 6:42

I was always told that searching, finding, and processing your data [for a GIS project] is 80% of the work. That's the tough part. As a grad student, researching and finding data sources will be a necessary and essential task you'll need to master.

That said, you're looking for "open data." Just type in a few combinations of what you're looking for on Google ("traffic deaths") with the words "open data" or "open data portal" and you'll get closer to what you want. A few US cities have opened up data like this. I don't want to totally give away the answer for ethical reasons, but hopefully this will help. ;)

Scraping from Google Maps and that sort of thing takes some coding experience to get it done reasonably. Start with open data portals for now!
