Application of Multi-criteria Analyses in Road Safety Appraisal and Enhancement

Information pertinent to national road accidents for nineteen Asia Pacific countries were extracted and compiled in the study database. After univariate analyses of the database variables, they were deployed in safety and accident index development. For road safety appraisal, multi-criteria analyses of data envelopment analyses, DEA, were utilized. Evaluation of several combinations of inputs and outputs DEA led to selection of an output oriented DEA for detailed national road safety enhancement and appraisal. For years 1980 and 1994, different output oriented DEA with constant and variable returns to scales were deployed. For most of the selected countries and the study 15-year period, the developed road safety and accident index trends and DEA results were far from ideal, exemplifying major concerns regarding national road safety issues
