Note that the above formulas are only correct for each link k if the values in at
least 95% of the A vectors are all greater then zero or are all less then zero. If
this is not the case then the value entered in the B matrix must be zero for that
link and node. Using the values in the example above the B matrix becomes:

The idea behind the B matrix is to show how any one node that has been inside a
cordon will affect the traffic behaviour on some link or links in a certain way until
proven otherwise.
In the example it can be seen that by placing any of the nodes 1, 2, 3, 4, 5 or 8 in
the cordon a decrease in the traffic behaviour will occur on link X. This is not
however true on links Y and Z. Placing node 3 in the cordon will lead to an
increase of traffic behaviour on link Y by 4 units. This is obviously not an accurate
representation of what happens but the thought is that it will give a starting point
in helping to predict what the next cordon should look like and it will also become
