Abstract

Phillips, Ray, and Votey (1984) used a model of traffic casualties incorporating three independent variables—miles driven, rainfall, and alcohol consumption. They applied it to British data to attempt to determine (1) whether the British Road Safety Act of 1967 had an impact on road casualties and (2) the relative contribution of the three variables to road casualties. They accomplished the first objective using interrupted time series analysis, but fell victim to the ecological fallacy in their interpretation of the second.
