# Monitor live traffic from V2X signals with V2X2MAP open-source Android app and an ESP32-C5 development board

## Summary

V2X2MAP is an open-source project that lets you monitor live V2X (Vehicle-to-Everything) traffic signals using an ESP32-C5 development board and an Android smartphone. The ESP32-C5 board captures ITS-G5 signals on the 5.9 GHz band from vehicles and roadside units, including GPS coordinates, hazard alerts, traffic-light countdowns, and intersection geometry. Data is streamed via BLE to the Android app, which displays it on an offline map. The project also supports optional MQTT publishing, Wireshark recording, and a Python bridge with a local dashboard. Source code is on GitHub under MIT license. ITS-G5 is primarily a European standard, so practical use outside Europe is limited.
