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.
