Driven by the Internet of Things (IoT) revolution, the automotive industry is transforming itself significantly. Ve-hicles, once merely transportation machines, have now evolved into complex networks of sensors and actuators. This evolution heralds an era of intelligent and connected vehicles that collect and analyze real-time data, benefiting various sectors. In response to this scenario, this paper introduces a framework for collecting and processing vehicular information, leveraging the capabilities of Edge Computing. The framework integrates the OBD-II Edge (Freematics ONE+) technology for efficient data acquisition, harnessing the power of Edge Computing to enable real-time data processing and immediate response at the network's edge. Additionally, Node-RED and Kafka technologies are utilized for efficient data handling and routing, while the Timescale database ensures optimized storage of time-series data. Finally, the Streamlit tool provides an intuitive data visualization interface, enhancing data analysis and decision-making processes. Evaluated through a real-case scenario study, this proposal has proven viable and effective, providing analyses that directly contribute to vehicular safety and preventive maintenance, while also enhancing logistical operations in the field.
