Research on traffic control technology during the construction period of special long tunnels based on digital twins

This paper is based on a specific long tunnel project in Xinjiang, analyzing the issues present in the organization of tunnel traffic during the construction phase of the long tunnel. It proposes an intelligent traffic control sys-tem based on the digital twin model. The system consists of a data collection unit for gathering vehicle control information, an analysis and warning unit for integrating and processing the information obtained from the data collection unit, and a dispatch instruction unit for visualizing the results calculated by the warning analysis unit. The application of this system during the tunnel construction process can, to a certain extent, resolve the predicament of “invisible, unmanageable, and immovable” traffic within the complex logistics transportation organization of the long tunnel, providing insights and inspiration for the construction management of similar projects.
