From their site: Traffic Web Services from Yahoo! enable you to get traffic alert information from a given location. Use the Traffic REST API to customize your request with many parameters including indicating locations based on city state, zip code, or a combination of any of these things, latitude-longitude, whether to include a map image, or a search radius in miles. Traffic Web Services are also available through a [[http://developer.yahoo.net/traffic/rss/V1/index.html dynamic RSS feed]].
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
