The issue of "feedback" in the traditional four-step urban travel forecasting procedure (UTFP) has reemerged recently under the pressure of the Clean Air Act Amendments of 1990 and the Intermodal Surface Transportation Efficiency Act of 1991. FHWA now requires that metropolitan planning organizations implement feedback in the UTFP. The combined origin-destination and route choice (OD-UE) model solves simultaneously the trip distribution and the user equilibrium traffic assignment models and hence provides for feedback. Computer codes for the computation and calibration of combined models are available from various researchers. However, they lack detailed documentation and, moreover, require computer programming expertise to adapt to professional practice. In view of these drawbacks, this paper documents the coding of a macro that implements the OD-UE model in EMME/2. The scope of this effort was twofold: first, to respond to certain modeling requirements arising from modern urban transportation planning practice; second, to motivate transportation professionals to use more sound planning methods. The quality of the results obtained using data from the city of Winnipeg, Manitoba, Canada, supports the use of the macro in planning applications.
