Traditionally, vehicle detection for the majority of solar traffic signal controller applications hasbeen via the simple inductive loop. Whilst loops have proven to be generally reliable, theirdesign and functioning has led many industry professionals to question their practicality andcost-effectiveness.Clearview Traffic offers the M100 wireless vehicle detection system which utilises newtechnologies to ensure a smooth installation and deliver a long-term solution for ultra efficienttraffic signal control.Since theres no trenching or ducting involved, the slim line profile of the M100 can be installedquickly and easily and is also fully type-approved to the Highways Agencys specifications andalso is compatible with all types of MIDAS outstations and urban traffic light systems such asSCOOT, MOVA and System D.Intelligent traffic signal controllerNowadays, traffic lights have become an integral part of human`sday-to-day life. With this motivation in the mind, intelligent traffic signalcontroller aims at designing and implementing, a running model of solartraffic light controller which is controlled according to the density ofvehicle on road.
What does the intelligent traffic signal controller aim at? It controlsup to 4-phases traffic system with the traffic flow optimization strategies,optimize the traffic flow at network junctions, measurable improve trafficflow, reduce environmental pollution caused by traffic ,most importantlyincrease road safety.What can intelligent traffic signal controller bring us? It can reducevehicle-pedestrian conflicts and reduce or increase waiting time, what ismore, the duration of green light can be adapted to the user`s needs.Therefore, it contributes to public safety and security on streets andsidewalks, reduce the risk of accident on road ways, cycle paths andsidewalks and make a city more attractive, improve the quality of life.The solar traffic signal controller just work on the solar panel, worktheory is as follows: life cycle costs typically 20% of existing technology,6 Watt to 45W Luminaries ,Battery selection with 10 yr guarantee,installation is easy, install the anti-skid unloaded the lamp pole, andinstall the bracket on the solar panel, adjust the solar panel`s direction andangle, then tight the screw at last.A pole traffic light is green other theree ploes are red they aretransmitting IR wave from the IR transimitting led IR automated vehicleignityion off circuit works nearby 3-5 inch area straight . It off the
ignition supply of the vehicle for stop.Use of intelligent traffic signal controller instead of other controllerssuch as PLC makes the smart traffic signal controller hardware a lowcost system. The program downloaded into the microcontroller enablesit to have a high accuracy timing, high independency and consistenctly,it enabales the proposed intelligent traffic signal controller system torealize traffic flow optimization strategies at a single or networkjunctions.I have one mounted over one of my work benches. I wanted to make it work butcouldnt find an electronic controller. Im not really into electronics and didnt wantto design my own. Then I came up with an idea to make it work. I went real oldschool mechanical by utilizing an old barbecue grill rotisserie, some unused powerdrill brushes, and a wooden disk with 3 brass pie shaped pieces glued onto its face-all stuffed in a little box on the wall behind my traffic light in a back room. Thelights change just right, long green, short yellow, long red, long green, ect...I thought I was being crafty/ingenious with this design but then a week after Imade the thing, I found an electronic controller on Amazon for cheapmoney.Anyhow here is my traffic light, just wish it had the shields over the lamps...The new traffic lights you are seeing are made out of arrays of light emitting diodes (LEDs).These are tiny, purely electronic lights that are extremely energy efficient and have a very longlife. Each LED is about the size of a pencil eraser, so hundreds of them are used together in anarray. The LEDs are replacing the old-style incandescent halogen bulbs rated at between 50and 150 watts. Most cities in the United States are in the process of replacing theirincandescent traffic lights with LED units because of three big advantages:LEDs are brighter. The LED arrays fill the entire "hole" and have equal brightness across theentire surface, making them brighter overall.
LED bulbs last for years, while halogen bulbs last for months. Replacing bulbs costs moneyfor the trucks and people who do the work, and it also ties up traffic. Increasing thereplacement interval can save a city big dollars.LED bulbs save a lot of energy.The energy savings of LED lights can be huge. Assume that a traffic light uses 100-watt bulbstoday. The light is on 24 hours a day, so it uses 2.4 kilowatt-hours per day. If you assumepower costs 8 cents per kilowatt-hour, it means that one traffic signal costs about 20 cents aday to operate, or about $73 per year. There are perhaps eight signals per intersection, sothats almost $600 per year in power per intersection. A big city has thousands of intersections,so it can cost millions of dollars just to power all the traffic lights. LED bulbs might consume 15or 20 watts instead of 100, so the power consumption drops by a factor of five or six. A city caneasily save a million dollars a year by replacing all of the bulbs with LED units. Theselow-energy bulbs also open the possibility of using solar panels instead of running an electricalline, which saves money in remote areas.
