For the OKI zones (1-1608), thesedata were taken from the 1995 database. In instances where the 1995 zones were split, theparking cost attributes for the new, consolidated system zones were assumed equal to theattributes of the "parent" zone.As shown in Figure 2.1, for the MVRPC zones, the daily parking rate was assumed to be as highas $1.90 2 (approximately equal to $5.00 in 2000 US$) in the center of the downtown area (lotsand garages between Ludlow and Jefferson), and to drop to $0.40 (approximately equal to $1.00in 2000 US$) near the limits of the downtown area (Patterson Blvd. and Sinclair College).Parking costs were assumed to be zero for all other MVRPC zones. Parking seek time wasassumed to be 1.0 minute for all CBD zones and zero for all other zones, while parking walk timewas assumed to be 1.0 minute in all zones. Similar data were used for work trip and non-worktrip purposes.2.1.2 Transit Availability: HbscTUse.txtTrip production rates for Home-based School trips include trips by regular public transit and byspecial school or "yellow bus" service. These trip productions are later discounted so that onlytrips by public transit are included in subsequent steps of the model. To discount the trip rates,each TAZ is assigned a discount factor corresponding to a transit use or availability code, asdetailed in Table 2.2 and shown in Figure 2.2. In Montgomery, Greene and Miami countiesyellow bus service is ubiquitous, except in parts of the city of Dayton and the Oakwoodneighborhood.2 Parking costs in the model are entered in $1978.Trip Generation - Build Socio-Economic Database 3
