Abstract: A method for generating profile data indicative of time dependence of a time dependent parameter for navigable elements of a navigable network. For the method, a relative value of a time dependent parameter associated with each segment of a set of segments of the electronic map is obtained for each time period of at least one set of time periods. The segments are then clustered into groups of segments based on the relative values of the time dependent parameter obtained for the segments in each time period of the at least one set of time periods. The relative time dependent parameter data associated with the segments of the group is next used to obtain, for each group of segments, an aggregate profile indicative of the time dependence of the relative value of the time dependent parameter for each of the segments of the group of segments.

Abstract: A method is disclosed for generating profile data indicative of the time dependence of a time dependent parameter, such as a parking related parameter, in respect of one or more navigable elements of a navigable network within a geographic area, each navigable element being represented by a segment of an electronic map. The method comprises obtaining, for each one of at least one set of a plurality of different time periods, a relative value of the time dependent parameter associated with each one of a plurality of segments of the electronic map in respect of the time period. The method further comprises clustering, for the or each set of time periods, the segments into groups of segments based on the relative values of the time dependent parameter obtained for the segments in each time period of the set.

Abstract: A method is disclosed for generating parking related data in respect of one or more navigable elements of a navigable network within a geographic area, each navigable element being represented by a segment of an electronic map, the electronic map comprising a plurality of segments representative of the navigable network. The method comprises obtaining positional data relating to trips made by vehicles in the navigable network, each trip being a journey between stationary periods indicative of the vehicle being in a parked state. The method comprises, for each one of the plurality of trips, analysing the positional data to identify a parking space search portion of the trip; and analysing the positional data corresponding to the parking space search portions of the trips to obtain, for each one of a plurality of segments of the electronic map, a parking related parameter associated with the segment.
