SUBAREA FOCUSING WITH UTPS DISTRIBUTION-SPLIT MODEL

The effect of a data reduction technique called subarea focusing on the accuracy of forecasts produced by the Urban Transportation Planning System (UTPS) distribution-split model is explored. The UTPS package is a product of the Urban Mass Transportation Administration and its distribution-split model is a default option of the UMODEL module of this system. The results of the sensitivity analysis of the UTPS distribution-split model to subarea focusing indicate that levels of zonal aggregations of 75 percent or less are suitable for conventional subarea modeling. Even higher levels may be acceptable for sketch planning purposes.
