摘要： A method of detecting the closure and/or opening of a navigable element forming part of a network of navigable elements within a geographic area. A passability parameter is associated with each segment of an electronic map representing the navigable network and indicates a likelihood of closure of the element represented by the segment. The value of the passability parameter decays over time. When a device is detected on the element represented by the segment, the passability parameter is increased, and when a closure report is received relating to the segment, the parameter is decreased. In one set of embodiments, when the passability parameter decreases below a first threshold value, the element represented by the segment is determined to be potentially closed. In another set of embodiments, when the passability parameter increases above a second threshold value, the closed element represented by the segment is determined to be opened.

摘要： 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.

摘要： There is provided a method for generating traffic data indicative of a traffic volume and/or traffic density within a navigable network in an area covered by an electronic map, the electronic map comprising a plurality of segments representing navigable elements of the navigable network. The method generally comprises obtaining positional data relating to the movement of a plurality of devices along the navigable elements represented by the segments of the electronic map; determining, using (at least) positional data relating to one or more congested segments within a region of the navigable network, an estimate of one or more average penetration rates for the region; determining a sample volume for a non-congested segment within the region based on the obtained positional data; and estimating, using the determined sample volume and a selected one of the average penetration rates for the region, a traffic volume and/or traffic density for the non-congested segment. Also provided are systems for performing the method. Accordingly, traffic volume and/or traffic densities can be estimated from probe data.

摘要： A method and system of detecting when a navigable element previously determined to be closed is in an open state is disclosed, the navigable element forming part of a network of navigable elements within a geographic area, the navigable elements being represented by segments of an electronic map. Positional data relating to the movement of a plurality of devices along the navigable elements of the navigable network with respect to time is obtained, and a navigable element is identified as being in a closed state based at least on the positional data and a first visit interval associated with the segment representing the navigable element. The positional data is then used to determine a second visit interval for the segment representing the navigable element, and the navigable element is changed to be in an open state when a parameter based on the determined second visit interval for the segment representing the navigable element passes a predetermined threshold value.

摘要： 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.
