Abstract

Emergency medical care is very effective to save the lives of injured people in traffic accidents. The heliambulance has been under operation since 1999, and it is expected to contribute for the emergency medical care. However, the heliambulance is allowed to land on the expressway under only some restricted conditions, because the heliambulance generates strong wind called downwash. In this study, the moving stability of vehicles under crosswind generated by a helicopter is investigated based on field experiments and numerical simulation. Based on these results, the possibility of landing of a heliambulance on expressways is discussed.
