Traffic aggregation and reporting in real-time
First Claim
Patent Images
1. A method comprising:
- collecting real-time traffic data for a network from one or more probes;
receiving a request from a navigation device for a first percentage of the real-time traffic data in the network;
identifying, using a processor, a cost function for each of a plurality of road segments;
ranking, using the processor, each of the plurality of road segments based on the cost function;
aggregating, using the processor, the first percentage of data including road segments having a rank above the first percentage of the total plurality of road segments in the network; and
transmitting the aggregated first percentage of data to the navigation device.

Abstract
Systems, apparatuses, and methods are provided for aggregating and reporting real-time traffic conditions. Real-time traffic data for a network is collected. A request from a customer is received for a percentage of the real-time traffic data in the network, the percentage being greater than 0% and less than 100%. The real-time traffic data in the network is aggregated. The aggregated real-time traffic data is reported to the customer.

1. A method comprising:
-
collecting real-time traffic data for a network from one or more probes; receiving a request from a navigation device for a first percentage of the real-time traffic data in the network; identifying, using a processor, a cost function for each of a plurality of road segments; ranking, using the processor, each of the plurality of road segments based on the cost function; aggregating, using the processor, the first percentage of data including road segments having a rank above the first percentage of the total plurality of road segments in the network; and transmitting the aggregated first percentage of data to the navigation device. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A method comprising:
-
collecting, from one or more probes, real-time traffic data for a plurality of road segments in a network; identifying, using a processor, a number of vehicles occupying each road segment of the plurality of road segments within a given time frame; calculating, using the processor, an average speed for each road segment at the given time frame; identifying, using the processor, a historical speed for the road segment at a comparable time frame; calculating, using the processor, a cost function based on the number of vehicles and a difference between the average speed and historical speed for each road segment; receiving a request from a navigation device for a first percentage of the real-time traffic data in the network; ranking, using the processer, each road segment of the plurality of road segments based on the cost function; aggregating, using the processor, the first percentage of the real-time traffic data in the network based on the ranking; and reporting the first percentage of aggregated real-time traffic data to the navigation device in a transport protocol experts group (TPEG-ML) file. - View Dependent Claims (14)

15. 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 perform;collect, from one or more probes, real-time traffic data for a plurality of road segments in a network; identify a number of vehicles occupying each road segment of the plurality of road segments within a given time frame; calculate an average speed for each road segment from the real-time traffic data at the given time frame; identify a historical speed for the road segment at a comparable time frame from historical traffic data stored in the at least one memory; calculate a cost function based on the number of vehicles and a difference between the average speed and historical speed for each road segment; receive a request from a navigation device for a first percentage of the real-time traffic data in the network, rank each road segment of the plurality of road segments based on the cost function; aggregate the first percentage of the real-time traffic data in the network based on the rank; and report the aggregated real-time traffic data to the navigation device. - View Dependent Claims (16, 17, 18, 19, 20, 21)
