Wilson (1970) gives another way to think about zonal interchange problem. This section treats Wilson’s methodology to give a grasp of central ideas. To start, consider some trips where there are seven people in origin zones commuting to seven jobs in destination zones. One configuration of such trips will be: where 0! = 1.
