Samenvatting

The crash risk in tunnels is lower than on the open road network, but the consequences of a crash are often severe. Proper tunnel design is one measure to reduce the likelihood of crashes, and the objective of this work is to investigate how driving performance is influenced by design factors, and whether there is an interaction with secondary task load. Twenty-eight drivers participated in the simulator study. A full factorial within subject design was used to investigate the tunnel wall color (dark or light-colored walls), illumination (three different levels) and task load (with or without a visual secondary task). The results show that tunnel design and illumination have some influence on the driver's behavior, but visual attention given to the driving task is the most crucial factor, giving rise to significant changes in both driving behavior and visual behavior. The results also indicate that light-colored tunnel walls are more important than strong illumination to keep the driver's visual attention focused forward.
