This experimental work is investigating how the ability to perform the visual tasks of driving at night is affected by (1) abrupt transitions between lit and non-lit sections of road, and (2) the interaction of fog and road lighting. We are using a 1/10th scale model of a road to measure the reaction times and detection accuracy achieved by a sample of drivers facing representations of two scenarios occurring at night: an obstacle in the road, and nearby vehicles changing lanes without signalling. At the same time, to place these detection tasks beyond central vision, the driver performs a continuously tracking fixation task located above the road ahead, similar to a gantry sign. This motion-controlled model is mounted in a five metre lighting chamber equipped with spectrum-tunable LED lighting and a fog generator.
