Traffic congestions have increased substantially in the last few decades. Our standard of living as a race has risen and a larger number of people can now afford automobiles. This idea proposes the use of personalized traffic signals that are broadcasted directly to the car's dashboard. These traffic signals will replace the traditional traffic lights that are placed at places where roads intersect. The use of personalized traffic signals can reduce the effect of traffic congestions by directing cars in a way that resolves the congestion in the most efficient way.
It could be used along with map services so that the automation system does not only consider the current traffic state but makes arrangements for everyone's movement so they get home in the shortest possible time. In cases where the is traffic congestion is in a low population area, it is only normal for such places not to have traditional traffic lights. The system will automatically detect the congestion and resolve it. It is likely that most of the congestions will be prevented from happening at all.
Such a traffic system will do more than to let people know when to move or stop moving. It can recommend a different route or tell you when it is more efficient to take a different means of transport. The estimation of the time taken to travel will be more accurate. Emergency situations can be prioritized without having to use a siren.
Traffic congestions usually result in a waste of time and money. Traffic congestions also have a pronounced effect on the invironment since they are a major source of noise and chemical polution. Violation of traffic rules will be easier to detect and the violators will be penalized more justly. Voice commands can be incorporated into the traffic. Artificial traffic congestiaons can be created to slow down fleeing criminals when necessary.
