Abstract
A method and system of detecting when a navigable element previously determined to be closed is in an open state is disclosed, the navigable element forming part of a network of navigable elements within a geographic area, the navigable elements being represented by segments of an electronic map. Positional data relating to the movement of a plurality of devices along the navigable elements of the navigable network with respect to time is obtained, and a navigable element is identified as being in a closed state based at least on the positional data and a first visit interval associated with the segment representing the navigable element. The positional data is then used to determine a second visit interval for the segment representing the navigable element, and the navigable element is changed to be in an open state when a parameter based on the determined second visit interval for the segment representing the navigable element passes a predetermined threshold value.
