Highway accidents remain a significant safety concern due to high travel speeds and delays in emergency response. Fast and dependable detection is essential to reduce injuries and prevent additional damage. This work presents a real-time accident monitoring approach that performs analysis directly on embedded edge devices. By processing data locally rather than relying on continuous cloud connectivity, the system achieves quicker response and reliable operation under varying network conditions. The method integrates deep learning–based visual analysis with motion evaluation across successive video frames to identify potential collision events. To improve reliability and minimize false alerts, detections are confirmed across multiple frames before final classification. Once verified, the system automatically sends an alert containing location details, time information, and relevant context through a 4G communication link to support prompt emergency response. Testing on embedded platforms shows that the system maintains an effective balance between computational efficiency and detection performance. Overall, the design provides a scalable and cost-efficient solution for enhancing highway safety through continuous real-time monitoring.
