Abstract

A method of detecting the closure of a navigable element forming part of a network of navigable elements within a geographic area. A server obtains positional data relating to the movement of a plurality of devices along the navigable element with respect to time. The positional data is used to determine an elapsed time since a device was last detected on the navigable element, and the determined elapsed time is compared to an expected time interval between consecutive devices being detected on the navigable element. The navigable element is identified as being potentially closed, subject to one or more optional validation steps, when the determined elapsed time exceeds the expected time interval, e.g. by a predetermined amount.
