Traffic light system completed.
The system prevents stand-offs between motorhomes and caravans on a narrow campsite access road where passing is difficult.
Drivers simply press the yellow button to request priority. Once the light turns green, they have 90 seconds to reach the other side safely.
The traffic lights communicate wirelessly with each other over a distance of approximately 250 metres through dense forest using LoRa technology — no internet or Wi-Fi required.
Both the hardware and software were developed together with a good friend. The entire system was built at around 80% lower cost than a quotation from a conventional traffic light supplier.
The system was tested in 36 different scenarios to ensure reliable operation under a wide range of conditions, including power failures, simultaneous requests, misuse, and heavy traffic flow.
