I posted the other day and briefly mentioned Yahoo’s new traffic RSS feed. If you fed it your city name or zip code it would give you an XML file with current traffic information. Cool, but not that practical for most people. Well now Greg has tied it all together with GoogleMaps. Tell it your zip code, it grabs the traffic data from Yahoo, and overlays it on a Google Map. Zoom in and out and click the traffic warning icons to see the specific data. If I didn’t take the El to and from work I would be using this constantly.
UPDATE (5/12/05): Apparently Yahoo has disabled the RSS feeds so Greg has moved to data from Traffic.com. I’ve updated the links.
