抜粋

Two experiments on the visibility of a direction sign and three emergency signs through fire smoke were carried out with subjects. In Japanese railway stations, direction signs, which are prescribed by rules of each railway company, and Emergency signs, whicti are prescribed by Fire Services Act, are installed. The emergency signs used in the experiments are an evacuation exit sign and two evacuation route signs. Smoke density, type of signs and yaw angles of the sign were changed in the experiments. Twenty subjects aged twenties were participated in the experiments. All subjects have normal sight. The experiments are planned with " Design of Experiment' As a result of statistical analysis with regression analysis, relational expressions of each sign about the visible distance, smoke density and yaw angles were derived.
