Travel Demand Model - OKI

OKI/MVRPC Travel Demand Model – Version 6.02. Zone System ConsolidationThe consolidated zone system consists of 2531 traffic analysis zones (2425 internal zones and106 external stations). The OKI zones were incorporated first (numbered from 1 to 1608),followed by the MVRPC zone system (numbered from 1609 to 2425). A GIS zone layer of theconsolidated system has been developed (see Figure 2-1). Both OKI and MVRPC revised theirzone system prior to the creation of the consolidated system. These revised systems provideadequate geographic detail for the present study, and thus no further zonal subdivision wasrequired. Per OKI request, Ohio County in Indiana has been excluded from the consolidatedregion. Equivalence tables between each agency's zone systems and the system developed forNorth-South Transportation Initiative are included as Appendix A.Zones in the consolidated system were also grouped into super-districts. This higher-levelclassification is intended for reporting summary statistics as well as for comparisons between themodel's estimated trip tables and observed data. A total of 16 super districts were defined andnumbered non-consecutively from 1 to 20, as shown in Table 2-1. The superdistrict system isdepicted in Figure 2-2.A revised set of cordon zones was developed by eliminating stations that lie along the commonborder between OKI and MVRPC, and between Montgomery/Greene counties and Miami County.The remaining stations were sequentially numbered from 2426 to 2531, by first incorporating theOKI stations, then the MVRPC stations and finally the Miami county stations. Provision was madefor additional zones (whether external or internal), by starting the numbering of highway nodesat 3000. The revised set of cordon stations is documented in Appendix B. Please refer to thekey at the end of the table for a description of each column.Table 2-1 Consolidated Zone System Super District DefinitionSuper District No. Name Consolidated Traffic Analysis Zones1 Boone Co. 1466-1550, 1606,16072 Butler Co. 691-992, 1589-1596, 15993 Campbell Co. 1255-13394 Clermont Co. 1128-1254, 16005 Dearborn Co. 1551-1587, 16086 - -7 Kenton Co. 1340-1465, 1603-16058 - -9 Warren Co. 993-1127, 1597, 159810 - -11 Cincinnati Center 251-316,12 Cincinnati North 243-246, 317-324, 328-338, 340, 341, 346-350,13 Anderson 1-39,14 Hamilton Co.
