Development of an automatic traffic light with pedestrian detection using Arduino, distance sensors, LEDs and an audible signal, with automatic adjustment transition in case of presence or absence of pedestrians.
Description
This work focuses on the development of an automatic signaling system that detects the presence of pedestrians and adjusts the state of the traffic lights accordingly. The system uses the Arduino Uno microcontroller, ultrasonic sensors for pedestrian detection, LEDs for the traffic lights and a buzzer for the audible notification when pedestrians are detected. The goal of the implementation is to reduce unnecessary waiting times, ensuring that drivers do not wait unnecessarily when there are no pedestrians wishing to cross the road and that pedestrians will have priority to cross the road.

Questions
How big is the PedestrianSense PCB?
It measures 170 × 105 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PedestrianSense use?
15 parts, built around the HC-SR04. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PedestrianSense KiCad files?
From the KostelidisDev/PedestrianSense repository on GitHub, at the commit this page was made from: the board is pcb/PedestrianSense.kicad_pcb and its schematic pcb/PedestrianSense.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PedestrianSense design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
