Abstract
AbstractUrban tunnel lighting is significant for driving safety and comfort. In order to investigate the relationship between the lighting parameters and driving comfort under different situations, this paper established a tunnel lighting system model based on Shenzhen Henglongshan tunnel by UC-win/Road. By designing tunnel lighting driving simulation experiments, the authors changed the parameters of the tunnel lighting system model and conducted a series of tests by the driving simulator under different lighting conditions. Through analysis of the driver’s eye movement data, this paper proposes that the minimum brightness of the tunnel lighting in the middle section is 0.5 cd/m2, and the lighting brightness threshold for safe driving of the driver is 2.2 cd/m2. The research results can provide a reference for the construction of tunnel lighting projects, and a theoretical basis for optimizing the design of tunnel lighting and improving the quality of tunnel lighting.KeywordsTransportation safetyVisual characteristicsTunnel lightingDriving simulationPupil area change rate
