1. A method, comprising:
- receiving probe data from a plurality of mobile probes;
deriving, from the received probe data, a traffic jam shape and traffic jam area based at least in part on a slope sign of a border of the traffic jam area estimated based on at least a portion of the probe data;
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 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.

10. An apparatus, comprising:
-
a processor; and a memory including computer program code, where the memory and computer program code are configured to, with the processor, cause the apparatus at least to perform operations that comprise; receiving probe data from a plurality of mobile probes; deriving, from the received probe data, a traffic jam shape and traffic jam area based at least in part on a slope sign of a border of the traffic jam area estimated based on at least a portion of the probe data; 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 operation 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A non-transitory computer-readable medium that contains software program instructions, where execution of the software program instructions by at least one data processor results in performance of operations that comprise:
-
receiving probe data from a plurality of mobile probes; deriving, from the received probe data, a traffic jam shape and traffic jam area based at least in part on a slope sign of a border of the traffic jam area estimated based on at least a portion of the probe data; 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 operation 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. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)

28. A system comprising:
-
means for receiving probe data from a plurality of mobile probes; means for deriving, from the received probe data, a traffic jam shape and traffic jam area based at least in part on a slope sign of a border of the traffic jam area estimated based on at least a portion of the probe data; means for 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 means, responsive to said means for determining, for 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, where the estimated time is based at least in part on when the estimated trajectory of the vehicle and the line representing the border of the traffic jam area intersect. - View Dependent Claims (29, 30, 31, 32, 33, 34)
