TRAFFIC LIGHT CONTROL USING A SMARTPHONE

The smart traffic light model has a traffic light for cars and pedestrians, a loudspeaker and a 7-segment display with 4 digits and a button for pedestrians that shortens the time of the red light for pedestrians and the green light for cars. The pointer counts down the transition from green for cars to green for pedestrians, and pressing the button enables faster switching of traffic light states and can be controlled via smartphone. The speed of the traffic light countdown has been adjusted with the loudspeaker. The model is fully adapted to blind and hard of hearing people when crossing the intersection.
