The traffic light is one of numerous leading aspects in our lives that we don’t appreciate anymore. The literal definition of the traffic light is a signal that uses red‚ green‚ and amber lights to control traffic. The traffic light is a lifesaving invention in the eyes of many people ever since 1868‚ when it was developed. Who would have predicted that a light could save multiple lives and prevent major accidents from occurring? The traffic light has transformed drastically over time. Currently

sTraffic lights‚ also known as traffic signals‚ traffic lamps‚ signal lights‚ robots in South Africa[1] and‚ in the past‚ semaphores‚[2] are signalling devices positioned at road intersections‚ pedestrian crossings and other locations to control competing flows of traffic. Traffic lights were first installed in 1868 in London[3] and are now used all over the world. Traffic lights alternate the right of way accorded to road users by displaying lights of a standard color (red‚ yellow/amber‚ and green)

Solar Powered Traffic Light Solar traffic lights are signaling devices powered by solar panels positioned at road intersections‚ pedestrian crossings and other locations to control the flows of traffic. They assign the right of way to road users by the use of lights in standard colors (red - amber/yellow - green)‚ using a universal color code (and a precise sequence to enable comprehension by those who are color blind). Most of the solar traffic lights have battery back-up for functioning during

)Concept Of Operations The city X wants to have a traffic system which shall sense the traffic flow‚ integrate the traffic lights together so they can react to the pattern to improve traffic flow‚ and provide a way for the traffic light system to be monitored and controlled. which will be connected with each other. The city X currently has 24 standard traffic lights. The locations of the current lights can be seen in Figure 1 in Appendix A. The signals all operate independently and are of the traditional

The fact is that there are too much old cars in the country which have such terrible exhaust system‚ together with the old traffic light system that was comply 20 years ago and it’s considered as a dull system in the modern generation (Echaves‚ 2013).

Vehicle Density based Traffic Signal Light There has been a need to automatically control things from a distance depending on a certain timing logic. In recent past there had been many instances of accidents on the roads‚ at the crossings near the colonies for the fact that there were no streetlights ON in the night when the visibility of the driver is poor. Even at the junctions such as T-junction‚ Y-junctions or circle we should be able to distribute the traffic in such way that
