Roads can be unpredictable at times, at one moment you be driving along peacefully and at the next you may be in an accident and that is why traffic control is enforced in the form of signals and markings to ensure the safety of all road users. Traffic lights are strategically placed on road to guarantee the safe flow of vehicles and have the basic colors of red, yellow and green but may carry according to different countries. The red colors tell users to stop, while the yellow symbolizes getting ready to go and the green means to get going. Green and red ones last longer than the yellow and sometimes the red light may even last for 5 minutes if there is some construction work going on or some obstruction on the road that is getting cleared. In cities with a low population, the traffic signals are turned off at night as there is almost no risk of any mishap occurring. Some lights also use sounds to improve their effectiveness and is extremely useful for people that have vision problems. When the light is red, there will be a small beep and when it turns green the beeping will sound continuously to tell people to move. The main purpose of signals may be traffic control but they were used long before the invention of auto mobiles. As early as the 1800s they were used to guide horse carriages and were fueled by gas and needed to be manually operated by a police officer.

Traffic management through signals not only makes people feel secure but is also an important tool used for safety. Some signals also have a camera system attached to them so that anyone that is breaking the rules can be caught directly. The cameras are linked to a main center that is responsible for collecting information to enforce the Traffic controllers in Sydney. They run around the clock and help guide the traffic through difficult times. Signals area form of control and allow harmony at intersections as they relay what to do and what not to do. Children are taught traffic signals at an early age from school or by the parents themselves so that right from the start they know that rules have to be followed. They are also extremely easy to learn and remember and you don’t even need to be educated to know what these signals mean. There are many advantages of traffic signals. A properly designed traffic signal system stops heavy traffic at an intersection allows vehicles from the other side or pedestrians to pass. They make sure that traffic moves continuously and does not get stuck and also reduces the intensity as well as the frequency of accidents especially those that happen from a certain angle and can be controlled.
