Traffic lamps are also called as road traffic lights, stoplights, stop and go lights, which are signaling gadgets positioned at road junctions, everyday pedestrian crossing & other areas to control flow of traffic. Traffic lamps can be seen in several places worldwide. Traffic light provides a proper way to the road users in different ways. Traffic light module employs a global color code so that comprehending the signal shouldn’t be an issue.
Traffic light controller:
The prime goal of traffic light controller is to offer control & coordination to make sure that traffic moves as safely and smoothly as feasible. This project employs LED lights for signal purpose & a microcontroller is employed for robotic change of indications at specific range of time intervals. Traffic LED light gets mechanically activated & deactivate by making corresponding port pin of the microcontroller “HIGH”.
A prototype of traffic light control system is made by using Infra-Red sensors along with major components Microcontroller and LEDs which are used for controlling traffic signals based on the density of the traffic. The junction taken into consideration is a four-side junction with the traffic flow on each side is only in one direction. This traffic light control system consists of the following three main components:
Display Unit: It consists of 3 LEDs: Green, Red and Orange on each side of the junction– a total of 12 LEDs of three colors are placed at the junction.
Detector Unit: It consists of a combined arrangement of photo diode and IR LED at every junction for detecting the presence of vehicles based on the change in resistance.
Controller Unit: This control unit contains a microcontroller which receives the output data from the IR Sensors and controls the glowing of LEDs based on the programming.
This traffic light control system works on the concept of fixed time allocation at each side of the junction which cannot be changed as per varying traffic density. Timings allotted at every junction are fixed .Sometimes higher traffic density at one side of the junction demands longer time duration for green signal compared to the standard allotted time.
Today you can find traffic light manufacturers that are readily offering high quality LED traffic lights at an affordable price. No doubt LEDs are the best option when it comes to saving energy and environment saving. Since Traffic light employs a large portion of space in our city, they must be replaced with environment friendly traffic control options such as LED light.



LED arrow boards are the latest introduction to the traffic control lamps that are used where a lane is closed & traffic should combine with other traffic in a contiguous lane. Manufacturers have many arrow board options to fit your work zone safety requirements.
The best thing is they provide a safe method for analyzing traffic patterns using different technologies. By seeing the arrow board we also recognize whether to go left or go right, merge left or merge right. From safety point of view traffic led lamps are the best gift your city can get.
Transportation specialists, traffic safety engineers, and auto makers have made significant advances in automobile & highway safety over the last 20 years. Municipalities and road planners are poised to make another significant jump in highway safety as they choose new LED highway lights or substituting existing highway lighting with advanced LED technology.
Traffic lights enable utmost vehicle competence at intersections. Also, they offer an easy and safe to comprehend signal that notifies motorists when it’s secure for them to go through a traffic intersection.
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.
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.
Digital signages have turned out to be an en excellent way to bring the attention of passing traffic. LED signs are growing in popularity worldwide because of their influential effect with ambiance, brightness and long range visibility.
LED display signages are helpful to nearly any kind of business when employed in the proper way. Being inventive and developing new & interesting ways to grab your consumers’ attention is the secret to incorporating interactive displays into your business & increasing engagement.
LEDs are the most advanced standard in traffic signals, mainly due to the Energy Policy Act of 2005 which set minimum standards for energy efficiency in traffic signal and pedestrian modules. The "Vehicle Traffic Control Signal Heads: Light Emitting Diode (LED) Circular Signal Supplement" specification effectively addresses the physical, mechanical, photometric, & electrical requirements for LEDs, encompassing environmental requirements for protecting LEDs from dust and moisture intrusion, including blowing rain. One of the unintended consequences of the transition to
Traffic management professionals around the world are leaving maintenance intensive and energy hungry incandescent lamps by the curb and heading for the robust, high-reliability advantages that
When it is about buying illuminated sign for your business - be it a gas station or grocery store you’ve 3 main options: fluorescent, neon or LED. Both fluorescent and neon have a long history & have established themselves dependable, yet recently LEDs have acquired attention for their vibrant & creative displays to attract customers.
manually.
On its face, LED warning signs looks more costly compared to typical emergency or warning lights used in traffic, but that’s because a lot of consumers don’t completely comprehend the advantages & savings of LED warning signs in traffic area.
LED diodes also gain from longer lifetime in comparison to typical lamps with a standard of fifty thousand hours compared to thirty thousand hours for a regular T8 fluorescent lamp. If you consider one replacement lamp per light into your equations, the regular lighting would cost you a supplementary £190.00 throughout their lifespan.
One of the greatest frustrations of city life is traffic, especially the bumper-to-bumper traffic that clogs the roads and pollutes the air. Unfortunately, this daily tribulation experienced by millions of city people is showing no signs of improvement. The situation is the same all over the world. In China, several thousands of motorists in a recent report were said to be trapped in a traffic jam that was about 100 kilometers long. In Texas, administrators have reported that congestion has grown everywhere all over the cities. In Mexico city a 20 kilometer drive through the city center can take over 4 hours longer than it would take the average pedestrian to walk the same distance.
• For longer distances individuals can help by opting to join public transport. Government should continuously improve the bus, metro, and rail system
