This project is an independent evaluation of a driver improvement program for unexceptional adult drivers, offered on a pilot basis in 1972-73 by Ford Motor Company to its employees. The program was conducted using four treatment groups which received different amounts of re-training. This report discusses the development and application of an evaluation model employing immediate criteria (operational success and survey results), intermediate criteria (performance tests before and after training), and ultimate criteria (crash and loss rates). Immediate and intermediate data are discussed together with comparisons of the treatment groups on biographical and driving record characteristics. It was found that two treatments consisting of several hours of classroom and on-street instruction resulted in 30%-40% increases in mean group score on an observational test of on-street performance. A smaller but still statistically significant increase was found for a third treatment comprising a self-teach course, but a control group showed no change. Small mean increases in headway were recorded for the three treated groups with marginal statistical support. The remaining tests revealed few significant differences. Limited re-testing three months after post-test suggested that the measured improvements were sustained for the two groups who were actively trained.
