LEGION Model Builder Help

Different Entity Types/Supplies per origin

It is possible to enter more than one row containing the same origin (for example Train N below) and to associate each row with a different Entity Type or Supply Type. You may need to do this when different Entity Types or Supply Types leave the same origin and head towards different destinations

The following example has the same single origin (Train N) represented on two rows: different proportions of passengers will alight from this train and make their way to different destinations: the street exit, train 1, or train 2.

When Arrival Profiles are automatically created on the Data Profiles sheet, they are given the name of the ‘Origin’; any origin that appears more than once will be automatically numbered ‘...#001’, ‘...#002’, in the usual LEGION manner (see Data profiles worksheet ).

A note on Entity Choice

If you would like Entities to select their own destination rather than prescribe a set percentage or absolute number, enter the letter c in the cells where origin and destination coincide. This means that Entities will choose their targets according to their shortest distance.

When this is imported into LEGION Model Builder the Final Destinations of the Demand Line in question will display ‘by Entity Choice’ parameters, rather than ‘by Percentage Weighting’.
