The authors analysed and reviewed the situations of traffic accident injuries resulting in permanent disabilities by examining 370,287 injured cases (persons) and the corresponding automobile liability insurance payments made since 1994 and thereafter. These cases were based on the Ministry of National Land, Infrastructure and Transport's computer data recorded since 1994, and from the compiled database on the national traffic accident of the Institute for Traffic Accident Research and Data Analysis (ITARDA).These data were restructured as a "permanent disabilities database" which has been prepared and updated since 1994, but many of these data taken in 1999 and onwards have not been firmly verified. The "permanent disabilities database" was prepared by matching the "compiled data on traffic accidents"and the "data on permanent disabilities with automobile liability insurance payments". Analysis of accident and resultant disability trends was conducted in relation to the nature of the collision, location, vehicle type and gender of victim. Through the analysis of the restructured "permanent disabilities database", it is found that determining the effects of vehicle safety structures (crashworthiness) and occupant protection systems are indispensable to the reduction of incidence of permanent disabilities and to the development of such structures, systems, etc. For the covering abstract see ITRD E141807.
