Abstract
A method and system for detecting frequent lane changes of moving vehicles are disclosed. A method for detecting frequent lane changes of moving vehicles including extracting the Z axis angular velocity values, and storing those Z axis angular velocities, from the Z axis angular velocity of which numerical product is negative, analyzing the Z axis angular velocities stored in the specific time period, and judging the number of the Z axis angular velocities with the numeral number 0. It is determined whether the vehicle has made frequent lane changes or not in its moving process, so that an active monitoring for vehicle travelling statuses is implemented, thereby normalizing driving behaviors, and reducing traffic accidents.
