The safety of a rail-highway grade crossing should be estimated by mixing information about causal factors such as train and traffic flows, types of warning device, and geometry with the accident history of the site. A theoretically sound and logically coherent procedure for doing so is suggested. This procedure is applicable not only to crossings but also to intersections, road segments, drivers, and vehicles. Current estimates of the safety effect of warning devices used at crossings are incorrect. This claim is supported in this paper. The aforementioned coherent procedure for estimating safety also enables corrected estimates of effectiveness to be furnished, which should be used in the allocation of resources to warning devices.
