Evaluation on Lateral Stability of Vehicle: Impacts of Pavement Rutting, Road Alignment, and Adverse Weather

The combination of pavement rutting, poor road alignment, and extreme adverse weather will seriously threaten the driving safety vehicles, whereas only a few these factors are commonly concerned. This study aims to efficiently evaluate impacts various conditions on lateral stability vehicle produce practical recommendation for maintenance in what concerns rutting. A systematic framework was, thus, developed conduct comprehensive evaluation vehicle, which incorporates single-factor test multi-factor based indicators obtained from Carsim simulations. model was established software by considering seven factors, including speed, width–height ratio (WHR) rutting sidewall, radius circular curve, superelevation, crosswind angle, friction coefficient, respectively. results show that behaves with satisfactory performance, regarding evaluating effect impact while across Stability suddenly fluctuate short time, due instantaneous wandering behavior crossing Additionally, sudden fluctuation phenomenon is greatly enlarged, inclined occur instability when WHR equals 5, particularly roll-over instability. It recommended concurrently confine greater than 10 coefficient 0.4, order ensuring stability. revealed speed leading affect stability, followed respectively, both essential outcomes this may contribute supplying guidelines controlling key making decisions maintenance.
