I should imagine you could measure direction too, if one is tripped before the other.
They may be for calculating speed, but without any further information, there's no way of telling what wheels belong to what vehicle, or how many wheels (edit: or more specifically, axles) a vehicle has - so it certainly wouldn't be viable for enforcement.
You can also estimate the size of the vehicle. based on how fast it it going and the time between front and back wheel you could calculate the distance between the wheels.
with two strips you can get a lot more data than if you just have one. count, direction, speed, size, and times the road is active. I dont know if they active measure all that but its possible.
Good point about direction. I couldn't imagine using this for enforcement, but I'm guessing you could be pretty confident any the number of axels but counting the ones that are the exact same speed and by the distance apart.
