Abstract:
When assigning a transit network with EMME/2, the basic results are the volumes on the transit segments and the boardings/alightings at the transit stops. Means to produce line-to-line transfer matrices at transfer nodes are not provided as a standard result output.
In this paper we show how such line-to-line transfer matrices can be computed for selected transfer nodes, without changing the assignment results. This is done with the standard EMME/2 software , by using a special network transformation at the selected transfer nodes. Details of this transformation are discussed and we show how the process has been automated by implementing it as a macro. The method is illustrated with an example from the Winnipeg standard demonstration data bank.
In the conclusions we discuss how this methodology can be extended to model other complex situations which are not covered by the standard model.

Introduction
When modelling transit networks, the basic results provided by the transit assignment in the EMME/2 software package are the volumes on the transit line segments, as well as the boardings and alightings at each transit stop. Of course, other information is also computed during the transit assignment, such as the number of initial boardings and final alightings at nodes, the auxiliary link volumes (e.g. pedestrian movements) and the various OD time component matrices.
These standard results cover the need of the g
