These models are stratified by proximity to the external cordon line. In total fivemodels have been estimated:• Centrally-located zones in Cincinnati (cordon location code 1)• Centrally-located zones in Dayton and Xenia (cordon location code 7)• Intermediate zones (cordon location code 2)• Close-to-the-cordon zones (cordon location 3)• Special trip generator zones (cordon location 5)Figure 8.2 shows the distribution of the cordon location variable in the consolidated zonal system.The last category listed above is comprised of zones where regional shopping, recreation and/oremployment centers are located. These zones generate more trips per inhabitant and per jobthan would be expected from their geographical location alone, and for this reason have beensingled-out as a separate category. Table 8.10 lists these special generator zones. Two of thesetrip generators, downtown Oxford and Withamsville, represent sub-regional shopping centers(large discount stores appear to be located in both zones).Total external trips generated at each internal zone were estimated from the expanded cordonsurvey data. Two further adjustments, besides those discussed in Section 8.2.1, were made tothe station volumes:• Total traffic counts at three stations in the MVRPC region were updated, per their request.Three station volumes were adjusted: Lower Valley Pike (station 2495), US 35 West (station2512) and SR 66 (station 2521). The update factor was calculated as:Update Factor =MVRPC Revised Station Volume TotalODOT Station Volume TotalTrip Generation - External Cordon Survey Analysis 48
