Hydroplaning and skid resistance analysis using numerical modeling

Abstract

Wet weather accidents can be caused by either poor skid resistance or hydroplaning. Due to a lack of theoretical and analytical models, the understanding of skid resistance has not improved over past decades. This study therefore aims to develop numerical models that could simulate hydroplaning and skid resistance. The first phase of the study involves hydroplaning simulations using the tire deformation profiles obtained from experiments conducted by the National Aeronautical and Space Administration (NASA). The hydroplaning speed relationship predicted from the simulation model is verified against the NASA hydroplaning equation. The model is then applied to different pavement grooving designs and the results are verified against experimental data. The second phase of the study involves relaxing the hydroplaning tire deformation profile assumption to allow skid resistance and hydroplaning simulations. Hydroplaning speeds and the skid numbers at different vehicle speeds obtained from the simulation closely agree with experimental results reported in literature.
