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.

Abstract: An improved method for matching traces derived from probe data to one or more line segments in a digital vector map. Points in a probe trace are provisionally matched one-by-one to line segments in the digital vector map to identify all possible matching candidates. A graph of the matching candidates is created having one or more paths. The graph has a plurality of sequential levels corresponding to the points in the probe trace. Each matching candidate is assigned to a level of the graph corresponding with trace point to which it relates. Edges are established between matching candidates in adjacent levels provided they are topologically related to one another. The graph is simplified and scored. The best paths deliver the matching results. The invention allows use of graph theoretic methods to find the best path through the graph, which in turn represents an efficient map matching algorithm. The concepts of this invention may be used in conjunction with longitudinal distance as matching criterion.

Abstract: The invention relates to a method of obtaining and storing data relating to a count of journeys made between origin and destination pairs in respect of different predetermined time periods. Positional data is received from vehicles, and filtered to obtain positional data relating to travel between each of a plurality of origin-destination pairs. The filtered positional data is analysed to obtain multiple sets of profiles. Each set of profiles represents a count of journeys made between the origin and destination in a plurality of predetermined time periods for each origin-destination pair. The different sets of profiles relate to different days of the week, and journeys having arrival or departure times in the predetermined time periods. The sets of profiles are used in a clustering operation to provide a reduced set of standard profiles.

Abstract: A method of determining a longitudinal position of a vehicle (100) relative to a digital map is disclosed in which real time scan data (200, 202) is determined by scanning a lateral environment around the vehicle using at least one range-finder sensor, said real time scan data comprising one or more depth maps, each depth map representing the measured lateral distance to surfaces in the lateral environment for a plurality of longitudinal positions and elevations.

The deemed current longitudinal position is adjusted based on said longitudinal offset to determine the longitudinal position of the vehicle (100) relative to the digital map.

Abstract: Probe data collected at times of low traffic density is analyzed to derive a Raw Road Design Speed Limit (RRDSL, 16) for each road segment or group of segments in a digital map. The RRDSL (16), comprised of longitudinally distributed speeds, is associated with the road segment and stored in a digital medium to indicate the limits of the road section in free flow traffic. The longitudinally distributed speeds may be limited by local speed limits or other business logic to establish a Legal Raw Road Design Speed Limit (LRRDSL, 17). Either the RRDSL (16) or the LRRDSL (17) can be further modified to smooth acceleration and deceleration rates between changes in the longitudinally distributed speeds to create an Optimal Longitudinal Speed Profile (OLSP, 18), which represents optimized energy consumption. A signal can be produced if a driver's current speed rises unacceptably above a longitudinally distributed speed in real time. The signal can be audible, visible and/or haptic.
