Abstract

A method of identifying navigable stretches that are partially closed, e.g. due to the presence of roadworks, in a navigable network within a geographic area. A server obtains positional data relating to the movement of a plurality of devices along a navigable stretch with respect to time in a given time period, wherein the time period is a period of non-congested traffic flow. The positional data is used to determine an average speed of travel along the navigable stretch in the given time period. The determined average speed of travel is compared to a free flow speed for the stretch, and the navigable stretch is identified as being partially closed when the determined average speed of travel is lower than the free flow speed by a predetermined value.
