How has the guided busway affected traffic on the A14?

It seems that there is no agreement about what the recently published statistics for usage of the A14 mean and why they have declined.

West of Huntingdon, where the A14 doesn't parallel the busway, the decline has been greatest (5%). Maybe that is due to dualling of the A421 between bedford and the M1.

At Fen Drayton, traffic fell by 2.7%, or 2526 vehicles.But Councillor Mike Mason, thinks it's due to the decline in economic activity.
