Get Real-Time Traffic Alerts with Traffic Web Services from Yahoo!

Yahoo! is shutting down the Traffic Rest API and the Traffic RSS Feed. There is no transition to a new or existing Yahoo! Traffic API at this time. Although the current APIs are going away, we will announce improvements to our Maps APIs in early 2011, which will include updated traffic features.

The Traffic Web Services from Yahoo! enable you to access real-time traffic alerts information for a given location. Build applications that use this dynamic traffic alert data to help you plan optimal routes and keep on top of your commute. Traffic data also makes a great addition to a mashup with Yahoo! Maps.

Traffic Web Service APIs

Yahoo! offers two interfaces for accessing traffic alerts data: a REST API and a dynamic RSS feed.

• Traffic REST API

  Use the REST API to build a traffic web services query with information about location (city, state, zip, latitude-longitude), the search radius in miles, and the severity of the alerts you're interested in. You can also get a map image for the visual location of each alert you get back.

• Traffic RSS Feed

  You can also access our traffic web services through a dynamic RSS feed. Use the same parameters from the REST API to build an RSS feed request, and then subscribe to that feed in My Yahoo! or your favorite feed aggregator. Or, use that RSS data in a mashup with Yahoo! Maps to build up-to-the-minute location-based applications.
