Abstract: In Intelligent Vehicle Infrastructure Cooperative Systems (IVICS), a high-precision vehicle positioning method utilizing Ultra-Wide Band (UWB) is proposed. Owing to remarkable wide band of radio signal, this UWB-based positioning method shows excellent anti-interference capability and multi-path immunity, which are essential for achieving high precision in practical traffic scenario. In this approach, several UWB nodes are deliberately deployed at the crossing with the help of roadside infrastructure in IVICS. Meanwhile, an algorithm aiming at Non Line of Sight (NLOS) error compensation is developed to improve the positioning performance. In a word, this method has been demonstrated the potential to achieve accurate, reliable, continuous and integrated localization.
