Abstract:
To study the effect of crosswind on traffic safety, wind force on as typical vehicles was obtained by wind tunnel test in simulated uniform wind field a passenger car and a container truck. Based on dynamics principle, the computation model of vehicle driving speed was established with considering wind force by analyzing its driving state on curved section of highway. Moreover, the speed limit values of typical models were proposed in the conditions of varied wind velocities and design speeds. The results show that wind force increases as its scale, and its effect on container truck is larger than that on passenger car under the same wind scale; when the design speed of highway is higher, the speed limit value will be more apparently affected by wind force. The result quantifies the effect of wind force on driving vehicle, and can provide theoretical basis and guidelines for highway safe operation in the wind area. 6 tabs, 4 figs, 15 refs.
