Traffic Lights

Topic

   Traffic lights, also known as traffic signals, traffic lamps, traffic semaphore, signal lights, stop lights, robots, and traffic control signals, are signalling devices positioned at road intersections, pedestrian crossings, and other locations to control flows of traffic.

   Rather than timers, "smart" or "intelligent" sensor-based traffic signals rely upon a system of sensors to detect when vehicles are present. When a vehicle on a side road arrives at the intersection, a sensor will detect it and cycle the lights to allow traffic on the side road to pass through.

   Traffic lights are sometimes centrally controlled by monitors or by computers to allow them to be coordinated in real time to deal with changing traffic patterns. Video cameras, or sensors buried in the pavement can be used to monitor traffic patterns across a city. Increasing the traffic handling capacity of roads.

Reflection

   They help movement and help conduct an orderly flow by giving right of way to some cars and not others. They not only make car traffic a lot safer but also pedestrian traffic. They help reduce the number of accidents and make collisions at intersections a lot less frequent.
