Honda has recently released a car traffic data system using Google Earth to present traffic status. According to newlaunches.com, the tool allows the company’s "InterNavi Premium Club" members to see traffic data overlayed on Google Earth.
Traffic information is displayed in three colors indicating "smooth (blue)," "busy (orange)" and "congested (red)." Initial service area only extends to 20 km around the center of Tokyo, Nagoya and Osaka, but the coverage will expand nationwide.
Volkswagen also recently showed off its own Google Earth-enhanced navigation service, although it looks like Honda may actually beat them to the market. No word on if or when it’ll make it to the North America market though.
