Travel Demand Model - OKI

OKI/MVRPC Travel Demand Model – Version 6.06.1.3 Executable Files6.1.3.1 Newnet60This program was updated from version 5.3 so that it is able to handle more nodes (21,000instead of only 16,000). The "build highway network" control file, build5.gen, was also updatedso that it now calls the new program version (see Table 6-1).6.1.3.2 ST050260This program builds the peak highway network by estimating peak link speeds using the BPRspeed-volume function with off-peak speed and observed volume counts as inputs. The peakspeeds were capped so that no link has a speed below 10 mph. This was necessary to avoidextraordinarily slow bus travel times on links with volume/capacity ratios over 1.0.6.2 Transit Network6.2.1 6.2.1 Data FilesThe consolidated base year transit network consists of 33 data files. The entire set was assignedextension "95C" for use within the Version 6.0 model stream. These files should reside in\data\trmaster. Some files are not used and thus contain no information; note however that thejob stream requires that they be present. In order to obtain the "95C" files, all data developedfor the MVRPC transit network were appended to the OKI base year transit network files (originalextension 95U).• RoutesAM.95c, RoutesMD.95c: peak and off-peak bus routes.• LRTAM.95c, LRTMD.95c, LRTDF.95: peak and off-peak LRT routes.• TrLinkAM.95c, TrLinkMD.95c, TrLinkDF.95c: transit links.• Sidewkpk.95c, Sidewkop.95c: peak and off-peak sidewalk routes.• StatData.95c: station data file.• PCWalk.95c: percent walk file.• XtraWkPK.95c, XtraWkOP.95c: additional walk connectors.• TFaresAM.95c, TFaresMD.95c, TFaresDF.95c: transit fares.• SysInDF.95c, SysInMD.95c, SysInAM.95c: Inet control files.• StaBusDF.95c, StaBusMD.95c, StaBusAM.95c: transit station equivalent centroid files.• DrvBusDF.95c, DrvBusMD.95c, DrvBusAM.95c: Drvlinks control files.• FarIEBAM.95c, FarIEBDF.95c: intercity bus zonal fares.• XAutoAM.95c, XAutoDF.95c, XAutoMD.95c: extra drive access connectors.• NodeTAZ.95c: TAZ location of each highway network node.• NodFZone.95c: SORTA Fare zone location of each highway network node.All TrLink files as well as the XtraWk and XAuto files contain no data.The parameters to be used by INET in building the transit network were adopted from the setupused by Model 54, and are as follows:• Default speed for walk modes (1 and 3): 2.5 mph.• Maximum length of links carrying mode 1: 1.5 miles.• Maximum length of links carrying bus modes: 30 miles.• Maximum speed for all bus modes: 75 mph.• Maximum headway for all bus modes: 240 minutes.Zones and Networks / 6 - Integration within Model 6.0 Jobstream22
