The trend in highway traffic accident fatalities has important ramifications in legislation, insurance, education and law enforcement. The present fatality rate in Iowa is about 5 deaths per 100 million motor vehicle miles, which is not greatly different from the national average. The work of Lauer and Swanson on reciprocal, logarithmic and linear trends of fatality rates shows that the number of traffic deaths per 100 million motor vehicle miles is decreasing in such a way that a linear extrapolation would indicate a zero rate by the year 1978. However, as a result of a more rapidly increasing traffic density, the yearly number of Iowa traffic fatalities is steadily increasing. The purpose of this paper is to illustrate this annual trend and to graphically illustrate the fatality prediction for the year 1958.
