Does anyone know of a public API for historical traffic data?

Some quick googling pulls up an API from Yahoo which offers real-time data, but I d be curious if anyone hosts a service for historical data - i.e., what was the "severity" (one of the attributes the Yahoo API returns) for a given location at a given date and time.

(I m going to guess that such a thing doesn t exist today, or at least no public options, as this would be an immense amount of data to store, but it never hurts to ask...)

While yahoo has shut down its traffic apis, there are a number of companies providing traffic information.

These guys certainly have the data, but I don t know how easy it is to get access to the API: http://inrix.com/developers
