Dynamic Location Referencing Segment Aggregation
First Claim
1. A method comprising:
- identifying a plurality of connected road segments and corresponding traffic information for each of the connected road segments;
aggregating, by a processor, the connected road segments into a fewer number of dynamic location reference (DLR) segments than the plurality;
calculating, by the processor, a traffic value for each of the DLR segments, each traffic value being a function of the traffic information for the connected road segments of the respective DLR segment; and
outputting an indicator of the DLR segment and the traffic value for at least one of the DLR segments.

Abstract
In one embodiment, road segments are aggregated for DLR. A plurality of connected road segments and corresponding traffic information for each of the connected road segments are identified. A processor aggregates the connected road segments into a fewer number of dynamic location reference (DLR) segments than the plurality. By testing different possible combinations, road segments with similar congestion are grouped. The processor calculates a traffic value for each of the DLR segments. Each traffic value is a function of the traffic information for the connected road segments of the respective DLR segment. An indicator of the aggregated DLR segment and the traffic value for at least one of the DLR segments is output.

16. 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 perform at least the following, combine road segments into groups based on dynamic traffic data; and reporting a travel time or travel speed for the combined road segments. - View Dependent Claims (17, 18)

19. A non-transitory computer readable medium including instructions that when executed by a processor, instruct the processor to:
-
calculate a ratio of congested links to total for each of different groupings of a collection of road segments including the congested links and non-congested links; selecting one or more of the different groupings, the selecting being a function of the ratios for the different groupings; determine travel information of vehicles for each of the selected different groupings; and outputting the travel information for the selected different groupings. - View Dependent Claims (20)
