This study presents the development and evaluation of a Wireless Blind-Spot Monitoring System with Real-Time Motion Detection and Risk Estimation using YOLOv11 and Optical Flow on the NVIDIA Jetson Orin Nano, designed specifically for utility vehicles such as the Toyota Hilux 2.4 FX 4x2 M/T. The system aims to enhance driver awareness and safety by providing real-time object detection and motion tracking in the vehicle’s blind spots through a non-intrusive Heads-Up Display (HUD). It integrates four ESP32-CAM modules for video capture, wirelessly transmitting data to the Jetson
Orin Nano for processing. YOLOv11 is utilized for object detection while a CUDA- accelerated optical flow algorithm, in conjunction with OBD-based vehicle speed input, is
employed for estimating the relative motion of surrounding objects. Experimental results demonstrate strong object detection performance with a mean
Average Precision (mAP@0.5) of 0.78 and consistent tracking of moving objects. Real- time processing was achieved with an average inference time of 0.06 seconds per frame,
though memory constraints on the Jetson Orin Nano presented limitations. Speed estimation tests yielded mean absolute percentage errors ranging from 4.4% to 69.1%, depending on object distance and motion complexity. A bird’s-eye view (BEV) map was integrated into the HUD for intuitive spatial awareness. The system was deployed and evaluated across 30 road trips in urban environments, with user surveys indicating improved driving confidence and reduced distraction. This study concludes that the proposed system offers a scalable, affordable, and real-time solution to blind-spot monitoring, contributing to safer road conditions and intelligent vehicle systems in developing transportation infrastructures.
