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, wherein the network of navigable elements comprises a plurality of navigable elements connected by a plurality of nodes, the method comprising:
- obtaining positional data relating to the movement of a plurality of devices along each one of a set of two or more alternative incoming navigable elements at a node of the network with respect to time;
using the positional data to determine a count of devices in a sequence of consecutive devices that have selected a given one of the set of two or more alternative incoming navigable elements from among the incoming navigable elements of the set;
comparing the count to a predetermined threshold to determine whether another one of the set of two or more alternative incoming navigable elements at the node is closed, wherein the threshold is specific to the incoming navigable element in relation to which the count of devices is determined; and
identifying the other one of the set of two or more alternative incoming navigable elements as being potentially closed when the count exceeds the threshold.

Abstract
A method of detecting the closure of a road element is disclosed; the road element being one of a set of alternative incoming or outgoing elements at a node in a network of navigable elements. A server obtains positional data relating to the position of a plurality of devices with respect to time traversing the node. A count is determined of the number of devices in a consecutive sequence of device selecting a given one of the navigable elements from among the set of elements. The count is compared to a predetermined threshold to determine whether another one of the elements is closed. The threshold is based upon the relative probability of the element to which the count relates being taken from the set of road elements.

11. A system for detecting the closure of a navigable element forming part of a network of navigable elements within a geographic area, wherein the network of navigable elements comprises a plurality of navigable elements connected by a plurality of nodes, the system comprising one or more processors operable to:
-
obtain positional data relating to the movement of a plurality of devices along each one of a set of two or more alternative incoming navigable elements at a node of the network with respect to time; use the positional data to determine a count of devices in a sequence of consecutive devices that have selected a given one of the set of two or more alternative incoming navigable elements from among the incoming navigable elements of the set; compare the count to a predetermined threshold to determine whether another one of the set of two or more alternative incoming navigable elements at the node is closed, wherein the threshold is specific to the incoming navigable element in relation to which the count of devices is determined; and identify the other one of the set of two or more alternative incoming navigable elements as being potentially closed when the count exceeds the threshold.
