I want an example of how to get boarding matrix
The BRDINGS skim matrix in PT "extracts the average number of boardings used by the “attractive” routes between zone pairs."
"Attractive" routes mean the routes that are used within the O-D pair, therefore the routes with a probability > 0%, as calculated during the route evaluation stage.
The BRDINGS skim matrix represents therefore a weighted average of the number of boardings between the O-D pairs, where the weights are these probabilities.
An example of usage is the calculation of the average number of transfers between O-D pairs, by including the statement below within the PT SKIMIJ Phase, obtaining the average number of transfers skim matrix:
;NUMBER OF TRANSFERS (excluding the first boarding = total boarding – 1)
