Cannot Cannot I Get A Green Light
On December 10th within the year 1868, the first traffic signal light was placed into service. The bulky, primitive device employed colored lamps that were fueled by gas to be used after dark, and semaphore arms. It required an operator to attend it always that it was in use. Twenty three days after that first traffic signal light went into service, it exploded injuring the police officer who was assigned to run the lights and signals. This unfortunate event brought into question the practicality of implementing traffic signal lights.
Despite the volatility, and ultimately disastrous results, of using the first traffic signal light, stalwart inventors and engineers pursued the concept. As an increasing number of traffic amassed on streets and roadways, using stop signs and officers standing on boxes at intersections became less and fewer practical and an increasing number of dangerous.
Sometime around 1912 the first electric traffic signal was put into use. These initial units only had red and green lights, however. In 1917 in Salt Lake City, Utah, a series of traffic lights were linked together, thus ‘connecting’ six sequential intersections. This system was operated manually with a single switch.
In 1922 Garrett A. Morgan made application for a patent on a traffic signal light of his own design. The patent was granted the following year. This started the parable that Morgan was the inventor of the traffic light.
Between the time the first traffic lights were introduced, and the early 1960’s many improvements were made, and lots of experiments conducted. The most important problem with traffic signals to that point was simply that they were dependent on timers only. East-west traffic would get a green light for 3-minutes, and then a timer would trigger a green light for the north-south traffic and so on. The lengths of push button switch black time could possibly be adjusted, but these settings frequently created problems with the flow of traffic.
Within the early 1960’s traffic engineers started to implement “inductive loops” to regulate intersection traffic flow. The loops, which could detect vehicles in specific lanes at intersections controlled the lights’ timers. The inductive loops would switch the lights to accommodate the traffic at hand, based on the time of day. No more sitting at red traffic lights for two-3-4 or 5 minutes – even if there was no cross-traffic present. Traffic engineers basked in a deluge of praise from drivers.
In the 1970’s technological advances in metallurgy, plastics, and rubber started changing the best way vehicles were manufactured and what they were being manufactured with. Not was everything from the dashboard to the fenders manufactured from high-iron content steels. It was along with these advances that the myths of tripping traffic lights began. Since then, it has gotten worse yearly as more alloys, plastics, and rubber are utilized in the construction of vehicles.
It seemed logical that the amount of weight present at an intersection is what would trigger a green light. This can be a myth. It also seemed logical that the mass present at an intersection would trigger a green light. This can also be a myth. Since people were unable to make traffic lights trip by adding weight, or by having more mass to their vehicles, they started to hunt other answers. The last most popular myth is that there’s an invisible curtain that, when broken by a vehicle, triggers a green light. It’s thought that the curtains only cover a portion of the lane, and if you don’t violate the curtain, you don’t get the green light. This can also be a myth.
Actually, inductive loop technology is quite simple. An inductive loop is nothing but a really large, very weak electromagnet. The term ‘inductive loop’ refers to electromagnets used in industry to detect iron. They’re commonly used in numerous industrial applications. They are inexpensive to make, install and maintain.
Inductive loops at traffic lights are created by burying large coils of thin copper wire slightly beneath the road’s surface. The wires are covered with either push button switch black black tar or rubber. A small current runs through the wire, thus making it into an electromagnet. The loop is connected to a meter which measures changes inside the loop. Magnets react to iron not plastic or rubber or aluminum. So when enough iron is present within the loop, the traffic light cycles to green.
The vehicles which have the best trouble tripping lights are motorcycles and mopeds, followed by small cars and trucks, after which raised 4x4s and SUVs. Drivers of these vehicles often sit undetected at traffic lights wasting fuel, getting rained on, their engines overheating, and their irritation growing.
To positively trigger your green lights, you’ll be able to drag a bowling ball-sized piece of iron around on the ground but that will not work if it’s inside your trunk. That is too far from the weak sensing field of the loop. In the trunk, you’ll need two or three large iron balls. OR you can install a Signal Sorcerer® traffic light changer http://signalsorcerer.com/.
Signal Sorcerer® traffic light changers use their own technology to make inductive loops detect your vehicle it doesn’t matter what size, weight, or mass it’s. Simply install the Signal Sorcerer® under your vehicle, and the inductive loops that control traffic lights will detect your vehicle, and provde the green light!
Signal Sorcerer® requires no power, lasts a lifetime, is legal everywhere, installs in lower than five minutes without any tools, and is completely guaranteed. Signal Sorcerer® traffic light changers have been in use around the globe for years, and units can be found for every application including police motorcycle divisions, security vehicles, fleet vehicles, and personal conveyances.
