Claim:
1. A method, performed by a computer processor, for detecting a lane change by a moving vehicle, said method comprising: detecting in real time, using said computer processor and a Global Navigation Satellite System (GNSS) receiver coupled to the moving vehicle, that a first heading of the moving vehicle has met a parameter defining a first stable heading; detecting in real time, using the GNSS receiver and said computer processor, that a second heading of said moving vehicle has subsequently met a parameter defining an unstable heading; detecting in real time, using the GNSS receiver and said computer processor, that a third heading of said moving vehicle has subsequently met a parameter defining a second stable heading within a pre-determined time parameter and that said second stable heading equals said first stable heading within a pre-defined margin; and generating, by said computer processor, an indication that said moving vehicle has performed the lane change.
