UNUSUAL TRAVEL POINT DETECTION DEVICE AND METHOD FOR DETECTING UNUSUAL TRAVEL POINT

摘要

PROBLEM TO BE SOLVED: To provide an unusual travel point detection device and a method for detecting an unusual travel point, in which data on an unusual travel point on a road can be collected by widely used sensors.;SOLUTION: An unusual travel point detection device detects an unusual travel point that is a point where unusual travel in a width direction of a road occurred, in which travel history data from a vehicle, including the position of the vehicle, a slewing value that is a value indicating a physical amount of slewing of the vehicle, is obtained, and slewing values contained in a plurality of travel history data are corrected to slewing values associated with each of preset points subject to calculation. By calculating a reference slewing value, which is an average slewing value, from a plurality of the slewing values associated with the same point subject to calculation and calculating a level of deviation of travel history data subject to the detection of an unusual travel point from the reference slewing value, a point with a large level of deviation from the slewing value is detected as an unusual travel point.;COPYRIGHT: (C)2015,JPO&INPIT
