Assessing Localization Technologies for Pedestrian Collision Avoidance

2026-05-18

AI Summary

This study addresses the limitations of pedestrian collision warning systems in intelligent transportation due to insufficient positioning accuracy and poor environmental robustness. It presents the first systematic comparison of Ultra-Wideband (UWB) and Bluetooth 6.0 for vehicle-to-pedestrian localization performance and evaluates their feasibility as alternatives or complements to Global Navigation Satellite Systems (GNSS). Integrating high-precision ranging with low-latency communication, experimental results demonstrate that both UWB and Bluetooth 6.0 significantly enhance positioning accuracy and stability in typical urban and obstructed environments. These improvements substantially strengthen pedestrian situational awareness, thereby providing a robust technical foundation for highly reliable, proactive collision warning systems.

Abstract

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.
