traffic monitoring

The OpenTrafficMap initiative has introduced the ESP32-C5 C-ITS receiver board, which uses 802.11p / ITS-G5 V2X communication over the 5.9 GHz WiFi 6 spectrum for traffic management. Peter Holzhauser has forked the firmware for this receiver and ported it to the Waveshare ESP32-C5-WIFI6-KIT development board, adding Bluetooth Low Energy (BLE) streaming capabilities. He also developed the V2X2MAP open-source Android app to interface with the board, allowing users to monitor live traffic and visualize detected nodes on the OpenTrafficMap website. The ESP32-C5 C-ITS receiver board includes an ESP32-C5-WROOM-1 module, a GPS module, and an Ethernet port with Power over Ethernet (PoE). The V2X2MAP app captures signals from vehicles' on-board units (OBUs) and roadside units (RSUs) on the 5.9 GHz V2X band, collecting data such as GPS coordinates, speed, hazard alerts, traffic light countdowns, and intersection geometry. The app can update maps offline and refresh data via MQTT. The source code for the firmware and the V2X2MAP app is available on GitHub under an MIT license. The firmware has been adapted for the Waveshare ESP32-C5-WIFI6-KIT, which is available for purchase online. Users are cautioned about legal considerations regarding the reception and forwarding of ITS-G5 radio data, particularly concerning GDPR compliance in Europe. The ITS-G5 standard is primarily used in Europe, while other regions may rely on C-V2X technology.
