GPS mapping enriched with historical traffic speed data

May 30, 2007 Satellite navigation can already tell you the shortest route from A to B, or the way that uses the most high-speed freeways - but on a gridlocked arterial freeway, speed limits are more of an insult than an indication of travel speed. That's why Tele Atlas have included new information in their latest U.S. mapping data so your SatNav system can analyse 2 years' worth of historical traffic speed data and tell you which route is likely to get you there fastest at a particular time of day.
