Determining speed information
First Claim
1. A method, said method comprising:
- obtaining or holding available map data representing, at least in part, a travel network; and
determining at least one speed profile for at least one selected link of said travel network at least partially based on speeds represented by a plurality of probe data points of one or more probe data sets of a plurality of probe data sets and a weighting function for weighting said speeds represented by said plurality of probe data points of one or more probe data sets of said plurality of probe data sets, said one or more probe data sets associated with said selected link for which said speed profile is determined,wherein;
each probe data point represents a position and a speed, andsaid at least one speed profile is at least partially determined by calculating one of one or more weighted mean speeds, one or more weighted speed percentiles, or one or more combinations thereof for said selected link or for one or more subsequent segments of said selected link.

Abstract
Methods, apparatuses, systems, and computer program products are presented for determining a speed profile for a selected link of a travel network. Map data representing, at least in part, a travel network is obtained or held available. At least one speed profile for at least one selected link of the travel network is determined at least partially based on speed represented by a plurality of probe data points of one or more probe data sets of a plurality of probe data sets and a weighting function for weighting the speeds represented by the plurality of probe data points of one or more probe data sets of the plurality of probe data sets. The one or more probe data sets are associated with the selected link for which the speed profile is determined.

14. An apparatus comprising at least one processor and at least one memory including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least:
-
obtain or hold available map data representing, at least in part, a travel network, and determine at least one speed profile for at least one selected link of said travel network at least partially based on speeds represented by a plurality of probe data points of one or more probe data sets of a plurality of probe data sets and a weighting function for weighting said speeds represented by said plurality of probe data points of one or more probe data sets of said plurality of probe data sets, said one or more probe data sets associated with said selected link for which said speed profile is determined, wherein; each probe data point represents a position and a speed, and said at least one speed profile is at least partially determined by calculating one of one or more weighted mean speeds, one or more weighted speed percentiles, or one or more combinations thereof for said selected link or for one or more subsequent segments of said selected link. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A non-transitory computer readable storage medium including one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform:
-
obtaining or holding available map data representing, at least in part, a travel network; and determining at least one speed profile for at least one selected link of said travel network at least partially based on speeds represented by a plurality of probe data points of one or more probe data sets of a plurality of probe data sets and a weighting function for weighting said speeds represented by said plurality of probe data points of one or more probe data sets of said plurality of probe data sets, said one or more probe data sets associated with said selected link for which said speed profile is determined, wherein; each probe data point represents a position and a speed, and said at least one speed profile is at least partially determined by calculating one of one or more weighted mean speeds, one or more weighted speed percentiles, or one or more combinations thereof for said selected link or for one or more subsequent segments of said selected link. - View Dependent Claims (28, 29, 30, 31)
