Research on the impact of the locations of luminaire failure on traffic safety in highway tunnels.

Objective: The safety of highway tunnels hinges heavily on proper lighting infrastructure, yet luminaire failures pose an ongoing challenge. The study aims at assessing the impact of the locations of luminaire failures on highway tunnels safety.

Methods: The research involved conducting 300 on-site scenarios with 29 participants, with simulated drives in visual recognition experiments.

The impact of different service states of tunnel lighting on traffic safety.

The service states of tunnel lighting will directly affect the lighting conditions, which affect traffic safety. Therefore, it is imperative to evaluate and predict traffic safety accurately in different lighting states. In this research, three hundred experimental scenarios of the service states of tunnel lighting were designed and implemented to evaluate the impact of different service states of tunnel lighting on traffic safety.
