Printed Circuit Boards in Traffic Control
Driving down the street, you are used to observing the traffic lights on nearly every corner. But have you ever given a second thought about how stoplights function? For the past hundred years or so, traffic lights have helped control the flow of cars moving through cities in an effort to reduce collisions, pollution and commute time. In the 1970s, engineers added printed circuit boards to create the modern lights that use the red, yellow and green phases we know today. As vehicles begin to incorporate new technologies we can expect to see the change in how cities manage traffic through stoplights. New PCB capabilities are expected to allow stoplights to communicate with vehicles in close proximity so that drivers will know when the lights will change and what their expected commute time is. This can lead to a further reduction in pollution and can help cars safely navigate crossroads.
