Beat the Traffic by Triangle Software is web and mobile application that provides live traffic information on road maps in over 130 metropolitan areas. Beat the Traffic uses real-time data from multiple sources, including the US Department of Transportation.
The Beat the Traffic API allows developers to access and integrate the functionality and data of Beat the Traffic with other applications and to create new applications. Some example API methods include accessing and retrieving speed data, route information, and images from traffic cameras for integration into other applications.

In 2011, we learned that even our cars and trucks were going "social" when Salesforce.com announced its partnership with Toyota. However, the social capabilities of the partnership were limited in scope (car diagnostics, tune up reminders, etc.). What if your car could prevent you from driving a certain route because it knew what areas were traffic-heavy? That car sounds "social" in a fuller sense; it might be possible with the new Beat the Traffic API.
