Abstract: The lighting of tunnel has a great influence on the safety of tunnel driving. It is difficult to simulate the real driving environment in the traditional design. BIM technology has technical characteristics such as intuitive, efficient, dynamic simulation and other technical characteristics, which is beneficial to highway tunnel lighting design. Digital virtual sand table and ray tracing technology based on BIM can simulate the real driver′s perspective and experience the real physical lighting environment. In view of this, this paper studies the application of BIM technology in real-time dynamic simulation of highway tunnel lighting for reference.
