ABSTRACT
With the acceleration of urbanization and the continuous growth of transportation demand, intelligent transportation has become an essential approach to addressing urban traffic issues. As a powerful tool for integrating spatial data visualization and analysis, three-dimensional geographic information systems (3D GIS) demonstrate extensive application potential in the field of intelligent transportation. This study aims to enhance traffic management efficiency and optimize travel experiences by thoroughly investigating the application mechanisms of 3D GIS in intelligent transportation. By integrating multi-source heterogeneous data, a comprehensive traffic information platform based on 3D GIS was constructed, which combines virtual reality, big data analytics, and Internet of Things (IoT) technologies to achieve real-time traffic condition monitoring, optimized route planning, and traffic accident simulation. The results indicate that this platform significantly improves the spatial representation capability of traffic data and enhances decision-support effectiveness while providing traffic management departments and the public with a more intuitive and interactive user experience. The innovation of this study lies in its pioneering integration of high-precision 3D modeling technology with dynamic traffic flow data, overcoming the limitations of traditional two-dimensional GIS in expressing spatial complexity. Furthermore, an adaptive traffic flow prediction algorithm was proposed, effectively improving the accuracy of short-term traffic forecasting. Overall, this study not only verifies the technical feasibility of 3D GIS in intelligent transportation but also lays a theoretical and practical foundation for its further promotion and application, contributing significantly to the advancement of smart city construction.
