Traffic accidents rose from 2001 to 2005. For example, 155,814 traffic accident in 2005 did not include they compromised or took medical treatment by themselves. Therefore, the number of casualties caused more than national police agency, ministry of the interior published data.
Incomplete and ambiguous data of traffic accidents accord with rough set theory concept. The study use rough set theory to analyze the characteristics and rules of accidents to national police agency, ministry of the interior in 2005. Rough set theory can remove the redundant records, simplify the attribute-value table, discover the attribute association and induce the proper decision rules.
Basing on the characteristics of the accident rules, attributes were influenced by attributes, vehicle attributes, environmental attributes and troublemaker attribute. The cause of accident and the rules of general and major accident had the same number of attributes, the classification is mickler the total accuracy is lower, the classification is less the total accuracy is higher. Applying rough set theory to the protective equipment and mobile phone rules show that troublemakers will be injured 96%, dead 3%, some injured and the others dead 1% probably.
The study provides evidences showing that rough set theory is a useful tool for the analysis of incomplete and ambiguous data. The study was being conducted in which results from the whole set of data is presented and interpreted in order to obtain a better view of the condition of traffic accidents and be able to increase the effectiveness of the decision-making process. |
