Uniformity predicts pedestrian reassurance better than average illuminance

Reassurance describes the degree of confidence a pedestrian might have to walk, a critical concern where there are national plans to promote walking rather than driving for local journeys. This paper describes a field study carried out to measure the reassurance benefit of lighting using the day-dark method. The results suggest that reassuranc is better predicted by uniformity or minimum illuminance than it is by average illuminance, which is the conventional metric.
