Traffic Signals offer maximum control at intersections. They relay messages of both what to do and what not to do. The primary function of any traffic signal is to assign right-of-way to conflicting movements of traffic at an intersection. This is done by permitting conflicting streams of traffic to share the same intersection by means of time separation. By alternately assigning right of way to various traffic movements, signals provide for the orderly movement of conflicting flows. They may interrupt extremely heavy flows to permit the crossing of minor movements that could not otherwise move safely through an intersection.

When properly timed, a traffic signal increases the traffic handling capacity of an intersection, and when installed under conditions that justify its use, a signal is a valuable device for improving the safety and efficiency of both pedestrian and vehicular traffic. In particular, signals may reduce certain types of accidents, most notably, right-angle (broadside) collisions. You can see those glittering LED countdown timers that are readily installed in many intersections. LED traffic countdown timers are quite useful when it comes to guiding the traffic in the safest possible manner. Made of high quality LED timer countdown used in traffic intersections give signals to the motorists when to stop and when to leave.

Sometimes in freezing winter and sometimes in sultry summer, sometimes in sunny days and sometimes in rainy days, the working environment for traffic lights is relatively harsh, thus traffic lights has higher requirement for stability. General lights with incandescent bulbs have an average life expectancy of 1,000 hours, while halogen light bulbs have 2,000 hours, so the resulting maintenance costs are high. LED traffic lights lifespan is about 80,000 hours and do not suffer from damages caused by filament shocks or glass broken problems.

LED traffic signals help regulate vehicle movement at junctions or you can say they allocate Right of Way for each direction. Signals aren’t necessary when the vehicle numbers are very low, but when the number of vehicles increases close to the capacity of the road, then they control the vehicle movement possibly reducing road rage or even pollution(since vehicles can turn off the engines during red).

Traffic signals are actually supposed to create platoons of vehicles (grouping), so individual vehicles don’t travel at high speeds and cause danger to pedestrians at crossings. Nevertheless, traffic signal is the most important thing in our life and we must obey them to avoid any kind of mishap.
