METHODS AND SYSTEMS FOR DETECTING A CLOSURE OF A NAVIGABLE ELEMENT
First Claim
1. A method of detecting the closure of a navigable element forming part of a network of navigable elements within a geographic area, the method comprising:
- obtaining positional data relating to the movement of a plurality of devices along the navigable element with respect to time;
using the positional data to determine an elapsed time since a device was last detected on the navigable element;
comparing the determined elapsed time to an expected time interval between consecutive devices being detected on the navigable element; and
identifying the navigable element as being potentially closed when the determined elapsed time exceeds the expected time interval.

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.

11. A system for detecting the closure of a navigable element forming part of a network of navigable elements within a geographic area, the system comprising at least one processor arranged to:
-
obtain positional data relating to the movement of a plurality of devices along the navigable element with respect to time; use the positional data to determine an elapsed time since a device was last detected on the navigable element; compare the determined elapsed time to an expected time interval between consecutive devices being detected on the navigable element; and identify the navigable element as being potentially closed when the determined elapsed time exceeds the expected time interval.
