closely, within 1% regionally. Work trips from within the corridor to the CBD were underrepresented by 5%. Regionally, the model was overrepresenting trips to OSU by just 3%. There were specific travel markets that were weak, including a 27% underestimation of tours from the corridor to OSU. Work tour productions and attrac- tions were well estimated by the model. Almost all mar- kets were represented within 10% of the CTPP totals. District- to- district tours for all purposes were com- pared with the CTPP and household travel survey. The CTPP results were scaled as before, but the survey records were not scaled. The modeled work tour distri - bution is shown in Table 4. The observed journey distri- bution is shown in Table 5. Table 6 displays the ratio of the modeled to the observed distribution. 38 INNOVATIONS IN TRAVEL DEMAND MODELING, VOLUME 2 FIGURE 1 Districts used for analysis.
