1. A method comprising:
- receiving probe data from a plurality of mobile probes;
analyzing at least one pair of instances of the probe data;
based on the analysis of the at least one pair of instances of the probe data, determining a slope of the border of a traffic jam;
responsive to identifying a polarity change in the slope of the border of the traffic jam, estimating a border of the traffic jam based at least in part on the polarity change;
determining a traffic jam shape based on the border of the traffic jam;
determining when and at what point a vehicle enters a traffic jam area as defined by the border, and an estimated trajectory of the vehicle within the traffic jam area, the estimated trajectory being determined at least in part based on the traffic jam shape; and
based on the determining, generating and sending a message to the vehicle informing the vehicle of at least an estimated time when the vehicle will exit the traffic jam area.

Abstract
Disclosed is a method, apparatus, system and computer program configured to process traffic data and provide relevant information to a driver of a vehicle. A method that is disclosed includes receiving probe data from mobile probes; deriving, from the received probe data, an approximate traffic jam shape and traffic jam area; determining when and at what point a vehicle enters the traffic jam area, and an estimated trajectory of the vehicle within the traffic jam area; and based on the step of determining, generating and sending a message to the vehicle informing the vehicle of at least an estimated time when the vehicle will exit the traffic jam area.

8. An apparatus comprising at least one processor, and at least one memory storing computer program code, with the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:
-
receive probe data from a plurality of mobile probes; analyze at least one pair of instances of the probe data; based on the analysis of the at least one pair of instances of the probe data, determine a slope of the border of a traffic jam; responsive to identifying a polarity change in the slope of the border of the traffic jam, estimate a border of the traffic jam based at least in part on the polarity change; determine a traffic jam shape based on the border of the traffic jam; determine when and at what point a vehicle enters a traffic j am area as defined by the border, and an estimated trajectory of the vehicle within the traffic jam area, the estimated trajectory being determined at least in part based on the traffic jam shape; and based on the determining, generate and send a message to the vehicle informing the vehicle of at least an estimated time when the vehicle will exit the traffic jam area. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein with the computer-executable program code instructions comprising program code instructions configured to:
-
receive probe data from a plurality of mobile probes; analyze at least one pair of instances of the probe data; based on the analysis of the at least one pair of instances of the probe data, determine a slope of the border of a traffic jam; responsive to identifying a polarity change in the slope of the border of the traffic jam, estimate a border of the traffic jam based at least in part on the polarity change; determine a traffic jam shape based on the border of the traffic jam; determine when and at what point a vehicle enters a traffic j am area as defined by the border, and an estimated trajectory of the vehicle within the traffic jam area, the estimated trajectory being determined at least in part based on the traffic jam shape; and based on the determining, generate and send a message to the vehicle informing the vehicle of at least an estimated time when the vehicle will exit the traffic jam area. - View Dependent Claims (16, 17, 18, 19, 20)
