A number of safety concerns persist with modern crosswalks. People are distracted by things in their car, or their surroundings can make it hard to see oncoming pedestrians. With today’s self-sufficient power technologies, available sensors, and cheap low-power wireless communication protocols, it is possible to create digital signage to warn of oncoming pedestrians. By using distance sensors such as ultrasonic or infrared sensors, systems can detect where objects, or in this case people, are with respect to a sensor on a fixed pole. With low-powered illumination technologies like LEDs and low-powered IoT communication protocols like ZigBee, a system can communicate …
