This research aims to study the causes of the accident of the oil tanker truck by Query all 150 sets story the causes of the accident of the oil tanker truck all 3 factors contains a reasons caused by humans. Vehicles and the environment and the use of Analytical Hierarchy Process to find out the cause of the accident oil truck Analytical Hierarchy Process in order to make them aware of the problem and the conditions causing the problem clearly all queries with 150 sets of data analysis researchers analyzed data from the causes of the accident of the oil tanker truck 70% of 100%. Analysis Hierarchy Process used to find out the weight of importance which is to bring up weight had come to average and bring up the weight of importance that have been put into the matrix and then compare individual pairs then find out the weight of the criterion an evaluation of the consistency index ratios and consistency to make the comparison evaluates the importance of evaluation criteria in the later levels or alternative weight analysis of different alternatives under the objectives of the causes of the accident of the oil tanker truck from the results of the analysis of Hierarchy Process it found that the compliance rate is equal to the value of 0.009. or 0.009%. Located in the criteria acceptable values to decide whether the results are consistent which shall not exceed 0.10 or 10% for 5 or more factor comparison.
