METHOD FOR ANALYSING TRAFFIC INFORMATION USING GEOMAGNETISM DETECTOR

摘要

The present invention relates to a method for analyzing traffic information by using traffic information data collected through a geomagnetic detector. The method for analyzing traffic information comprises the steps of: receiving real-time information transmitted by an unit sensor part (including a geomagnetic detector) installed at each point from at least one gateway; generating and storing respective traffic status information parameters by using the real-time information; calculating normal distributions for the respective parameters by using information within a preset period among information on the traffic status information parameters; and comparing at least one parameter normal distribution for a first point, at which the unit sensor unit is buried, among the normal distributions for the respective parameters with real-time information of the first point among the real-time information and when it is determined that the real-time information of the first point is out of a three sigma range of the parameter normal distribution for the first point, informing the abnormal status.
