We propose a flexible method for extracting traffic information from social media. The abundance of
microposts on Twitter make it possible to tap into what is going on as users are reporting on what they
are actually observing. This information is highly relevant as it can help traffic security organizations
and drivers to be better prepared and take appropriate action. Distinguishing 22 information categories
deemed relevant to the traffic domain, we achieve a success rate of 74% when individual tweets are
considered. This performance we judge to be satisfactory, seeing that there are usually multiple tweets
about a given event so that we will pick up what relevant information is out there.
