Application in prevent urban road traffic congestion based on rough set theory and genetic algorithm

The decision table of the relationship between reason and type of reflecting road congestion was established. The attributes reduction method based on rough set theory combined with genetic algorithm was presented. This method removes redundant rules from decision table and finally the main factors causing road traffic congestion are found. The test result showed that this algorithm in analysis of causese for traffic congestion is efficient, and that it provides scientific basis for decision making of preventing urban road traffic congestion.
