INFLUENCE OF LIGHT LEVEL ON THE INCIDENCE OF ROAD CASUALTIES AND PREDICTED EFFECT OF CHANGING 'SUMMERTIME'

Previous studies of the apparent influence of daylight level and changes on the incidence of road casualties are reviewed and refi by analysis of official databases for Great Britain (1969-1973 an 1985-1994) and the USA (1991-1995). New statistical methods, bas on precisely computed altitudes of the sun for each accident location, are used to model casualty frequencies aggregated by we and hour of day, and locally evaluated associations between individual casualty incidence and solar altitude. Estimates of t altitude factor are interpreted causally to give counterfactual estimates of the effect of different clock time schedules on countrywide casualty numbers. (A)
