J - Jam avoidance
Jam avoidance - As more and more cars pour onto our roads, jam avoidance is becoming a major issue. You can also call services such as the AA before you set off to find out where the traffic hot spots are on your route, or a Trafficmaster system in your car can alert you to problems.
However, now advanced satellite-navigation systems such as Smartnav are being developed which continuously monitor traffic conditions and guide you along the quickest, clearest route. For more details log on to www.smartnav.com.
