Abstract

From accident data of Highway Department compiled from S3-02 form, vehicles are divided into 14 categories with only 6 vehicle types having significant numbers of accidents yearly and occurred in the majority of the days. These are motorcycle, car, small truck, big truck, van and bus, and trailer truck. This paper uses the dBase database of 15,171 highway accidents to study the significant variables of all six vehicle types. The comparison was conducted on 175 variables in 21 groups recorded for each accident using 95 per cent significant level. The methodology employed is the one-population, one-tail t-test to compare the variable (sample) average with the entire (population) average. The study shows that there are 37, 34, 37, 37, 35, and 35 significant variables for motorcycle, car, small truck, large truck, van and bus, and trailer truck, respectively. Then, the analysis is being done to derive the common and different aspects of these vehicle based accidents for various groupings. Explanations are given for the outcomes. Finally, the conclusions and suggestion are given for the analysis.
