A closed-loop nonlinear driver control mathematical model was developed promariyl to enable a better definition of prevailing preimpact conditions for use in studies aimed at minimizing the incidence and the consequences of single vehicle accidents through improvements in the performance of roadside design elements. Combined models of the driver and vehicle permit comparisons of simulated responses with experiments involving maneuvers at or near the upper limits of vehicle and driver control. The mathematical model is described, and results of several initial check-out runs are summarized. Specific values and ranges of the various input parameters have yet to be determined; however, approximate values have been obtained by qualitative analysis of the model behavior. (A)
