下一代智能交通系统亟需可靠的行人安全保障，依赖于主动的行人定位与碰撞预警。本文评估了超宽带（Ultra-Wideband）与蓝牙6.0技术在行人定位中的表现，二者具备高精度测距与低延迟通信能力，是车辆碰撞预警系统的有力候选。实验聚焦定位精度及环境鲁棒性等关键指标。初步结果表明，在特定场景下，UWB与蓝牙6.0可作为全球导航卫星系统（GNSS）的可行替代或补充，提升态势感知能力，实现及时的行人预警。
原文摘要 · Abstract (English)
Robust pedestrian safety is crucial to the next-generation of intelligent transportation systems. Such systems rely on active pedestrian localization and predictive collision alerts. Pedestrian localization can be supported by Ultra-Wideband technology and Bluetooth 6.0, which offer high-precision ranging and low-latency communication, making them promising candidates for vehicular collision warning systems. This paper assesses the localization accuracy of these technologies for pedestrian alerting and benchmarks their performance against Global Navigation Satellite Systems. Experimental evaluations performed in this paper focused on key performance metrics, including localization accuracy and robustness to environmental conditions. Preliminary results suggest that Ultra-Wideband and Bluetooth 6.0 can serve as viable alternatives or complements to Global Navigation Satellite Systems in certain scenarios, improving situational awareness and enabling timely pedestrian alerts.
