Traffic Light Control Using Solar Energy

Most solar traffic lights use led lamps as they are more reliable and have more advantages over other lighting devices like cfl lamps as they are more energy efficient have a longer life span and turn on and turn off quickly.

Traffic light control using solar energy.

Proposed solar based smart four way junction traffic light is to work independent of public power supply using abundant renewable energy solar. Existing traffic lights can also be upgraded with an auxiliary power. Energy efficient and reliable these contractor grade caution lights trickle charge standard 3 volt d cell batteries using an internal solar panel behind the lens to provide. Tesla has officially started rolling out traffic light and stop sign control to international markets.

Managing traffic at a four way junction. Eliminates road trenching cabling. The signals can be controlled through software programs and can be varied depending upon the location. Patented 32 bit microprocessor based controller provides very high processing power and a host of advanced features gprs wireless communication with control room enables remote monitoring and control of the solar traffic light system.

The solar traffic light is powered by battery which is charged during the day with solar pv and the battery continues working during the night. Ideally a smart grid system would generate enough renewable energy to power all the traffic and street lights in the city and still have some left over to sell back to the power companies. Solar traffic lights contain enclosures which house the batteries and the control panel circuitry. For example some places needs green signal to glow for long time.

Uses 2 4ghz zigbee wireless communication to control lamps. Solar power supply at each pole eliminates power supply wiring from one source. The objective of this project is to control the traffic signal with help of solar energy. This project has been developed as a model of traffic light controller.

Our solar assist amber led d cell traffic flashers with flash and steady on settings can be mounted to traffic control devices around construction and hazard zones. Operates on non conventional energy source i e solar.
