Average Speed Cameras - How Do They Work?

When driving through roadworks where there are a series of average speed cameras - 4 for example, is the average speed calculated between each camera in turn (1 to 2, 2 to 3, etc ) and so technically you could get 4 tickets, or is the overall average speed calculated between the first and last used to trigger a fine?

Camera to camera but it is fed into central date so you would only get one ticket.
