period, and the expansion of the data will conduce to concentrate the trips on few ODs,
with many empty cells in the matrix.
To correct this problem, at first a morning peak period from 7h00 to 9h00 was considered
to increase the distribution; and the trips occurring during others periods of the day were
included also in the distribution, but weighted by the time they occur in relation with the
morning peak, it means that those ODs exist in the morning peak but in a lower proportion,
depending on the time of the day they have been observed.
Each OD section has been expanded individually with the total number of passengers
observed in the morning peak hour. Originally, it was planned to expand the data for each
transit line at each section, which would result in a more accurate expansion factor, but the
data available did not permit to execute this process.
After expansion of each section, the double counting were automatically identified, that
means how many ODs of each section are passing thru other sections, and the total volumes
of each OD has been adjusted to match the passengers counts at each section it pass thru.
