Travel Demand Model - OKI

OKI/MVRPC Travel Demand Model – Version 6.02.1.3 External Station Data: A1001.extAll external stations or zones were assigned values for each variable listed in Table 2.1. Themodel does not actually require most of these data; in particular, the data are not used toestimate external-internal or external-external trip ends. Nevertheless they are expected as aninput, and so they have been defined following the Model 54 convention. All variables except thefollowing were assigned a value of zero:• Area type: 3 (suburban).• Workers per household: 1 worker per household.• Persons per household: 2 persons per household.• Autos per household: 1 auto per household.• Land area: 100 acres.• Non-work trip walk time at attraction end: 1.0 min.• Zone location code: 3 (close to the cordon line)• District number: varies depending on external zone location2.2 Executable Programs: ST120160.exeIn version 54 of the OKI travel demand model, Step 12 is performed by a stand-aloneexecutable, ST120153. One of the parameters of this program, NIZ, is the number of internalzones present in the demographic input file (A1002.95e). The source code was updated, renamedST120160 and recompiled with NIZ=2425, the appropriate number of internal zones inthe consolidated system.2.3 Step12 Batch, Control and Parameter FilesThe batch file that calls the Step12 subroutines was edited so that it uses the updated BuildSocio-Economic Database program, ST120160. No other changes were required to the controlor parameter files used in this step (see Table 2.3). A copy of the changed file is provided inAppendix A.Table 2-3 Build Socio-Economic Database Batch, Control and Parameter FilesFile NameSubdirectoryUpdateRequiredDescriptionStep12.bat \Batch\Model60 Yes Step 12 batch fileSt1201.inp Output directory No Parameter file, created by G.U.IModel.inp Output directory No Parameter file, created by G.U.ITrip Generation - Build Socio-Economic Database 6
