Abstract

Automotive Technology is improving every moment nowadays, but road accidents are still happening. Road accidents and fatalities in Malaysia are still high today. ASEAN NCAP is introduced to elevate vehicle safety standards, raise consumer awareness and encourage a market for safer vehicles in the ASEAN market. There are many testing protocols and tests created by ASEAN NCAP to achieve their objectives. However, the weightage of each item and each pillar in the ASEAN NCAP rating assessment is incompatible with the data on road accidents shown. According to the Ministry of Transport of Malaysia, Motorcyclist has the highest fatalities rate in road accidents. Besides, according to World Health Organisation (WHO), children are more vulnerable to road accidents. There is a lack of study on the priority weighting criteria for safety technology in assessment protocol for ASEAN NCAP rating. Hence, there is a need to design and develop a research instrument for weighting criteria for each pillar and item in the ASEAN NCAP rating assessment. The weighting for each pillar in the ASEAN NCAP rating needed to be determined by using Analytic Hierarchy Process (AHP). There is also a need to determine the effectiveness of the current rating assessment protocol. At the beginning of this study, a survey will be distributed to policymakers makers and automotive industry workers to collect their preferences on each item in the ASEAN NCAP rating assessment for 2021 to 2025. Analytic Hierarchy Process (AHP) will analyse data collected from the questionnaire. The results obtained in this process can help in determining the weightage of each item and each pillar in the ASEAN NCAP. Simultaneously, the effectiveness of the current ASEAN NCAP rating assessment can be determined. Based on the preferences of the respondents, Child Occupant Protection (COP) was the most important criterion in the ASEAN NCAP rating assessment. The top 2 priority items from the standpoint of automotive industry worker were side (child) and vehicle-based assessment, while seatbelt reminder (front) and blind spot detection were perceived for that by the policymaker. Out of these items, two of them are under the pillar of Child Occupant Protection (COP) and Motorcyclist Safety (MS). The ASEAN NCAP should be prioritising the weightage of items in the pillar of COP and MS. By manipulating the weighting of the criteria in the ASEAN NCAP rating assessment based on the happening traffic data, it will encourage the vehicle manufacturer to introduce more safety technologies to their vehicles. At the same time, road accidents and fatalities can be reduced.
