Weights of Road Accident Causes using Analytic Hierarchy Process

The development of technologies, economics and industrial sectors in Malaysia leads to increasing of motorization sector. The increasing of demand in motorization leads to road accident problems. Road accident problem is one of the critical incidents and various preventive measures have been taken to reduce the rate of road accidents. Thus, it is important to know the actual causes contributing to the road accidents. This paper aims to propose weights and ranks of five selected causes associated with road accidents using decision making approach of Analytic Hierarchy Process (AHP). The linguistic judgement data were collected from three experts in road accident analysis. The experts rate the pair-wise comparison in measurement scale from one to nine. The comparison scales were averaged prior to computing the weights of road accident causes. The results show that ‘driving faster than limited speed ’ is ranked as the highest cause with the weight 0.3242 and ‘obstructions (i.e., animals or weather) ’ is ranked as the lowest cause among the five road accident causes. Hence, the ranking gives rise to concerns about the contribution of the causes in reducing road accidents rate.
