Summary

The text discusses the ability of vehicles supporting Car2X via ITS-G5 to transmit detailed data such as GPS position and speed unencrypted over a 5GHz band. It highlights that trams in Graz also send data, allowing live tracking and visualization on maps. Many traffic lights in Graz support C-ITS, providing updates on lane configurations and signal statuses. Using an ESP32-C5, these data can be received from significant distances. The authors demonstrate how to collect and process this data, offering a live map showing tram locations and traffic light statuses, as well as historical data via Grafana. They call for public support for improving coverage by utilizing a custom-made device to capture C-ITS packages for community processing and visualization.

Signals

name description change 10-year driving-force relevancy
Open Data from Vehicles and Infrastructure Vehicles transmit detailed data openly, enabling real-time tracking and analysis. Shift from closed, proprietary vehicular data to open, user-contributory datasets. In a decade, expect comprehensive real-time traffic management and urban planning based on shared vehicle data. Increased demand for transparency and data-driven decision-making in urban infrastructure. 4
Advanced Traffic Signal Communication Traffic lights in cities are now capable of communicating their states and timing to the public. Transition from static traffic signal systems to dynamic, communicative ones that adapt in real-time. In ten years, urban areas will have highly adaptive traffic systems, reducing congestion significantly. Development of smart cities and the Internet of Things (IoT) integration in urban planning. 4
Community-Driven Data Collection Users are encouraged to collect and share traffic data for public benefit. Moving from government-controlled data collection to community-sourced input and collaboration. In the future, we may see empowered communities actively managing their own traffic data and infrastructure. The rise of participatory technology schemes and democratization of data. 5
