How does it all work, exactly?

• Users post traffic information to Twitter, often including hashtag words such as #bnetraffic, #sydtraffic.
• Through Twitter‘s standard application programming interface (API), a server accesses the tweets and sifts through them for city traffic information.
• The server also runs SAP BusinessObjects Text Analysis, which processes the tweets and filters out specific street names, city districts, and affected locations.
• The server then converts the locations into geographic coordinates and saves them along with the corresponding message.
• The iPhone app obtains the information from a garden-variety GEO-RSS feed and displays it to the user.
