Abstract
This report summarizes research to date concerned with identification of drowsy drivers from information contained in steering wheel and lane position data. Data analysed in this report was obtained from a Rockwell-Collins van driven on interstate and state highways in Iowa. Key results in this paper include the following: The type of steering wheel sensor can influence some of the more popular statistics promoted for drowsy driver identification. Weather conditions have a strong influence on the same statistics. Stochastic characterizations of steering wheel and lane position processes appear to have strong similarities. (Author/publisher)
