The number of cars on the roads of the world today is staggering. Some studies suggest that there are as many cars as there are households in many major cities. Of course you realize this for yourself when stuck in a traffic jam at the height of rush hour. Congestion is a major problem in many places. Trying to keep it moving is indeed a big challenge.
Motor safety is another big concern. Given the number of cars that are on the road the occasional traffic accident is inevitable. The problem can however be worsened by poor traffic management. A mistimed traffic light can cause chaos. A licensed driver should know the basic laws of the road without being told, but common sense does not often prevail on the roads.
The humble traffic light can be of huge help in controlling the traffic flow. There are those places that still use simple timed lights that change according to preprogrammed patterns, regardless of traffic conditions.
Some cities have realized that they can use their traffic lights to really help relive rush hour congestion with the help of NTP servers. Traffic lights controlled in this manner are helping to relive some of the congestion in major cities all over the world.
Instead of following those simple preprogrammed patterns of red, green and amber traffic lights can be made to respond to the needs of the road, allowing more cars to proceed in one direction than the other, allowing a passageway for cars stuck in long lines.
This is only possible though if all the traffic lights in a city system are all synchronized together, which can only be achieved with the help of an NTP server.
NTP (which stands for Network Time Protocol) is a widely used algorithm for time synchronization. An NTP server receives a time signal from a precises source (usually an atomic clock) and distributes that time to all the devices that are linked to its’ network (in this case all the traffic lights).
Once installed, the NTP server can constantly check and monitor the time on each individual device. This effectively ensures that all the traffic lights in a particular area are synchronized together. This allows for them to be controlled as a single, cohesive entity instead of individual, random lights. This allows for a higher level of traffic management than has ever been possible before.
