There is a significant difference between driving in a group of tunnels and in an ordinary single highway tunnel. The driver will experiences frequent alternations between light and dark environments when driving in a group of tunnels, which requires the driver to adapt to the changing light conditions. This can make it difficult for the driver to effectively perceive the driving environment, thus, increasing the risk of traffic accidents.This paper presents a case study of the Dayaoshan Tunnel Group, focusing on the special driving environment of the tunnel group section. The paper proposes a line of sight guidance programme that includes reflective rings, guide markers, contour markers, and other facilities. The effectiveness of the programme is evaluated quantitatively using driving simulation and psychology software E-prime. The experiment indicates that the line of sight guidance programme enhances the local luminance of the tunnel, enriches its internal visual environment, and provides drivers with necessary visual cues to improve driving speed stability, reduce reaction time, and enhance driving stability. Consequently, the programme effectively improves the safety level of the tunnel group.
