System and method for aggregating probe vehicle data
View Patent ↗A system and method for combining sequential map segments to aggregate, analyze, and display traffic data collected from one or more probe vehicles located on one or more of the map segments.
1. A method of generating traffic data associated with a targeted street, the method comprising the steps of:
(a) combining a plurality of sequential map segments associated with a first through street using a computing device, by identifying a set of map segments, wherein each map segment of the set of map segments is associated with a through street, and wherein each through street has a name; sorting the set of map segments according to the names of their respective through streets, and identifying, for each through street name, a subset of map segments associated with the through street name; determining, for each map segment of each subset of map segments, a longitude range including a beginning longitude and an ending longitude, identifying one or more nodes at which each subset of map segments intersects all other subsets of map segments, resulting in a plurality of nodes; sorting the plurality of nodes, so as to determine at least one pair of adjacent nodes; and determining for each pair of adjacent nodes of the plurality of nodes, the plurality of map segments extending between the pair of adjacent nodes, and combining the plurality of map segments;
(b) aggregating data received from one or more probe vehicles traveling upon one or more of the plurality of sequential map segments, using a computing device;
(c) generating the traffic data for the first street based on the aggregated data, using a computing device; and
(d) selectively transmitting the traffic data to one or more subscriber vehicles.
2. The method as set forth in claim 1 , wherein step (a) of combining the plurality of sequential map segments further includes determining for each map segment of each subset of map segments a latitude range, including a beginning latitude and an ending latitude; and sorting the plurality of nodes by the larger of the longitude range or the latitude range of each map segment associated with one or more nodes of the plurality of nodes.
