Abstract

The embodiment of the invention discloses a method and a device for data mining of a road traffic accident based on an association rule, which relate to the field of communication. In order to realize effective analysis and counting correlative with occurring condition factors of the accident and serve the jobs of accident prevention, treatment, decision and the like, the invention provides a technical scheme of: acquiring historical data in a prescribed time range and a prescribed road section range from the historical data of the road traffic accident as association rule mined data; determining the attribute of the traffic accident of the association rule mined data; acquiring a frequent item set according to the association rule mined data, the attribute of the traffic accident and the minimum support; and acquiring an accident association rule according to the frequent item set and the minimum degree of confidence. The method and the device are suitable for real-time dynamic traffic information services.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for mining road traffic accident data based on association rules. Background technique [0002] Intelligent transportation system is currently the best way to comprehensively and effectively solve the problems in the field of transportation, especially traffic congestion, traffic jams, traffic accidents and traffic pollution. Among them, the impact of traffic events (including accidents, traffic control, etc.) on traffic flow and road conditions is one of the hot research directions of intelligent transportation systems. [0003] At present, my country's road traffic conditions are characterized by low road grades, serious traffic jams, heavy pedestrian interference, and expressways that have just started. Therefore, it is necessary to rationally analyze traffic accidents, especially to use scientific and technological means to accurately grasp the characteristics a...
