Of all the new capabilities being introduced on portable navigation devices (PNDs) and GPS-enabled cell phones, real-time traffic is probably one of the most-wanted and hottest features today. It makes sense. After all, traffic plays a huge role during your travels, whether you're just making your everyday commute to work or heading off on a holiday.
All that said, just how useful are the traffic capabilities on GPS devices? Are there limitations? Where does the data come from? To help you (and me) better understand the technology and types of services, I talked with Nick Kiernan, Vice President of Business Development for TrafficCast, a traffic service provider. Check out our conversation below to learn more about the company, traffic data in PNDs and cell phones, and the future of GPS.
