The Japan New Car Assessment Program (JNCAP) was introduced in FY1995 to provide consumers with comparative information on the safety performance of new vehicles. From FY2000, the overall safety performance assessment of vehicles, which consists of full frontal collision test, offset frontal collision test and side collision test, was started. In this report, we investigated how the collision safety performances were changing from the annual transition of these test results. The relationship between the results of each test or the overall safety performance and the injury probability of drivers in traffic accidents was analyzed based on real-world accident data. As a result of analysis, the vehicle models with higher safety performance of JNCAP lower the fatality rate or the serious injury rate.
