It is reported that there are so many cars on the road as households and to prove it it would take just a short trip in rush hour to give account of this is very true. Congestion is a big problem in our towns and cities and is one of the most essential aspects of reduction of congestion control this traffic and keep it moving. Security is also a concern on our roads because the chances that all these vehicles that travel around without colliding with each other occasionally are close to zero, but the problem can be exemplified by poor traffic management. When it comes to controlling the traffic flows on our cities there are no more weapons than the humble traffic lights. In some cities these devices are simple synchronized lights that stop traffic on a path and allow the other and vice versa. However, the potential of how traffic lights can reduce congestion is now being done, and thanks to the synchronization by millisecond through NTP servers is It is drastically reducing the congestion in major cities of the world.

Rather than just simple time of green, amber and Red segments, the semaphore can respond to the needs of the road, which allows more cars going in one direction and while in others is reduced. They can also be used in conjunction with each other allowing green light for cars on main routes. However, all this is only possible if the traffic lights throughout the city system is synchronized and can only be achieved with an NTP time server. NTP (Network Time Protocol) is an algorithm that is widely used for synchronization purposes. An NTP server will receive a time signal from an accurate source (usually an atomic clock) and NTP software distributed between all devices in a network (in this case the traffic light). NTP server continuously will handle time of each device and ensure that it corresponds to the time signal, making the devices (traffic lights) are perfectly synchronized together allowing all traffic lights system is managed as a unique and flexible management system of traffic instead of individual lights at random.
