Abstract

Research was undertaken to determine vehicle size parameters influencing driver fatality odds, independent of mass, in two-vehicle collisions. Forty vehicle parameters were evaluated for 1,500 vehicle groupings. Logistic regression analyses show driver factors (belt use, age, drinking) collectively contribute more to fatality odds than vehicle factors, and that mass is the most important vehicular parameter influencing fatality odds for all crash configurations. In car crashes, other vehicle parameters with statistical significance had a second order effect compared to mass. In light truck-to-car crashes, "vehicle type-striking vehicle is light truck" was the most important parameter after mass, followed by vehicle height and bumper height, with second order effect. To understand the importance of "vehicle type" variable, further investigation of vehicle "stiffness" and other passenger car/light truck differentiating parameters is warranted.
