Study on Reliability Analysis Model for Transport of the Injured at Airplane Accident

Much more measures should be taken for the transport of the injured persons by airplane accident at airport. Road planning is essential to diminish the traffic jams around airport, which cause the delay of transport. Koike et al. proposed a simulation model for transport of the injured on the road network around airport and derived the proper activities in the assumed condition. The access road to airport should be connected to highway passing over the existing roads as to enable higher-speed drive and emergency close for accidents. Even if the connecting highway is in heavy traffic jams, ambulances should use the existing road network. In turn, if the existing road is out of use, they can run the highway. It means that rescue system should be invested with redundant road network. If the urgent route chooses both the highway and the existing road, we shall call it hierarchical road network. The reliability of such network maybe evaluated due to the composition of two types of road that have the individual reliability and are connected on some interchanges. This study aims to develop a reliability analysis model for transport of the injured at airplane accident considering the hierarchical road network. It can be evaluated with the various suppositions of transport activity. The equipment of some suppositions is very important for road planning considering an incident. Moreover, the model includes the risk evaluation model developed to evaluate not only transport activity but also medical activity for the injured. Through applying it to a hypothetical example of Chubu International Airport, which is now under construction, it proves that the proposal model implements the road planning for transport of the injured of airport accident.
