A quantitative analysis of the oncoming flow in front of a vehicle during gusty crosswind conditions is presented. Results from on-road measurements are connected to the results for steady state wind conditions published recently by Wordley. It is shown how the oncoming turbulent flow field typically develops during a gust 0.5 m above the ground. Based on the results, a quantitative range of turbulence scales, which are regarded as significant for vehicle driving stability, is developed. This range may help to set up boundary conditions more realistically within future numerical and experimental crosswind gust simulations.
