June 18, 2005 Though rush hour grows more intensive every year, the number of cars on the roads is still increasing and with emerging nations such as China and India on the brink of an automotive boom, research is developing intelligent systems to prevent traffic from grid locking completely in the future. A recent invention in the area of driver assistance systems is based on communication between vehicle and infrastructure (traffic lights). For example, in the future, speed recommendations could be transmitted to a vehicle as it approaches an intersection, enabling it to reach an optimum speed and make the best possible use of phased traffic light systems. Functions for monitoring the immediate vicinity of an intersection could also be particularly useful. Drivers can be warned of an increased accident risk in cases where it looks like another road user is likely to jump a red light because of excessive speed.
