A Cost–Benefit Analysis to Assess the Effectiveness of Frontal Center Curtain Airbag

Abstract

Abstract:Several new varieties of airbags are under consideration for development. However, their commercialization decision must be backed by a positive Cost-Benefit Analysis (CBA) outcome. In this study, we propose a CBA framework for the frontal center curtain airbag, a newly designed safety system intended to reduce the injury risk of rear-seat passengers. The proposed CBA covers not only economic benefits of the producer but also the effectiveness in sustainable reduction of the fatal and injury rate. In this context, with accumulated field data on road traffic accidents, a forecasting method reflecting the reduced casualties and the market share of vehicle sales associated with frontal center curtain airbag is utilized. Our results suggest that the use of frontal center curtain airbags helps to reduce the number of casualties with a Maximum Abbreviated Injury Scale (MAIS) of 3 or above by 87.4%. Furthermore, both the initial market penetration rate and price of the frontal center curtain airbag significantly influence its socioeconomic benefits. By evaluating the effectiveness of the frontal center curtain airbag, our study can contribute to the decision making for its commercialization.

Cost-Benefit Analysis to Assess the Effectiveness of an External Airbag and Autonomous Emergency Braking System

“…Based on the result of a simulation which investigated the reduced DVTOTALAEB, we developed the following Equation (1) that was estimated based on MADYMO. It is a simulation program for understanding the conditions of the vehicle accident [40]:…”

“…This is considered as a benefit in CBA process. Many previous studies have been adopted this approach [40][41] [42]. In terms of the cost savings from the reduction of injury severity levels, injury severity is expressed in terms of MAIS.…”

“…In scenario 2, the market penetration rates of AEB and AEB+EAB vehicles reached the maximum levels (30% and 15%, respectively) 20 years after their release. These scenarios and values referred to the cost benefit analysis of a new vehicle safety system, the frontal center curtain airbag [40]. To derive the market penetration rate of the AEB and AEB+EAB systems for the target period, we assumed that the AEB and AEB+EAB penetration rates had a tendency to increase in the manner of an S curve depending on the elapsed time.…”

О Защите В Боковых Автомобильных ДТП

“…Также известно что при боковом ударе порядка в 80% случаев удар приходится на пассажирскую сторону [79] Боковые и фронтальные ДТП суммарно являются самыми частыми и «смертельными» видами ДТП [76]. По статистике частота боковых ДТП составляют от 20% до 44.9% [9.C.24], [13],[41], [45], [47] несколько уступая фронтальным ДТП частота которых близка или превышает половину от всех случаев ДТП [9.C.24], [42], [43], [61] исходя из вышеизложенной статистики получается что несмотря на то что боковые ДТП происходят реже чем боковые, но по смертельности вполне приближаются к лобовым «Тем не менее, анализ национальных данных о несчастных случаях в Великобритании за 2004 год (STATS19) показывает, что лобовые столкновения по-прежнему являются причиной большинства смертей как водителей (58%), так и пассажиров на переднем сиденье (53%)» [44].…”
