Yahoo! offering traffic updates in USA

Now web users in America can plan their daily travel routes after referring to Yahoo's new web service. They would soon be able to check their local traffic conditions from Yahoo! Maps website. Yahoo! plans to offer this service integrated with online roadmaps. In addition, users will also be able to search them through normal searches.
Yahoo! claims it is the first of its kind offering which would provide speed conditions and dynamic traffic information, changing by the second, nationwide. It is a massive undertaking and would require inputs from road sensors and traffic cameras operated by state and local government entities.
Computer users would be able to get information by simply searching for city-name traffic and Yahoo! Search would take care of the rest. They would then be taken to relevant sections with maps and latest traffic reports. Sounds like a great concept. And Yahoo! are next planning to extend it to wireless devices which are going to be used mostly for this particular function as they are more accessible on the road. "
