ABSTRACT
With the rapid development of intelligent transportation systems, high-precision positioning technology, as one of its core supports, plays a significant role in enhancing traffic efficiency, ensuring travel safety, and optimizing resource allocation. This study focuses on the application of high-precision positioning technology in intelligent transportation, aiming to explore the key technical implementation paths and its potential impact on traffic management. By integrating the Beidou Navigation Satellite System with multi-source fusion technologies such as inertial navigation and geomagnetic positioning, a high-precision positioning method based on a dynamic error compensation algorithm is proposed, effectively addressing positioning deviation issues caused by signal blockage and multipath effects in complex urban environments. Through the construction of a simulation platform and real-world testing environments, the performance of this method in vehicle dynamic trajectory tracking, lane-level positioning, and traffic flow monitoring has been validated. Experimental results indicate that the proposed method achieves centimeter-level positioning accuracy in typical urban scenarios, significantly outperforming traditional single-technology solutions. Furthermore, this study delves into specific application scenarios of high-precision positioning technology in areas such as collaborative control for autonomous driving, intelligent traffic light optimization, and parking management, proposing corresponding technical fr ameworks and implementation strategies. The primary contribution of this research lies in overcoming the technical bottlenecks of high-precision positioning in complex environments, providing reliable support for precise perception and efficient decision-making in intelligent transportation systems, and laying a theoretical foundation for the deep integration and extensive application of related technologies in the future.
