Abstract
The problem considered in this work is the development of simulation method for simulating car crash which utilizes simple car—impact attenuator model developed in MATLAB. Usually, car crash simulation is done using full finite element simulation which could take hours or days depending on the model size. The purpose of proposed method is to achieve quick results on the car crash simulation. Past works which utilizes simple car—impact attenuator model to simulate car crash use continuous time model and the impact attenuator parameter is obtained from the experimental results. Different from the related works, this work uses discrete time model, and the impact attenuator parameter is obtained from finite element simulation. Therefore, the proposed simulation method is not only achieving quick simulation results but also minimizing the cost and time in obtaining the impact attenuator parameter. The proposed method is suitable for parametric study of impact attenuator.

The road accident involving vehicles is a primary concern for cities all over the world.The accident happens because most drivers cannot avoid certain situations that result in a crash between a vehicle and other objects [1]
(World Health Organization) data shows that the number of deaths per 100,000 population resulting from road accidents worldwide is increasing [2]
Summary
The accident happens because most drivers cannot avoid certain situations that result in a crash between a vehicle and other objects [1]. While the trend of road accidents may not be easy to alter due to increasing number of vehicles, mitigating the effects of an accident is possible, potentially reducing the number of fatalities. Technologies to avoid or mitigate the effect of accidents or crashes have been developed. The works [3,4,5,6,7] are categorized as active technology which assists the driver to prevent an accident. The works [8,9,10,11] are categorized as passive technology where the structure of the vehicle is designed to protect the passengers and driver from fatal
