Common use of Trip Generation Clause in Contracts

Trip Generation. The trip generation process of FLSWM determines trip productions (i.e., the number of trips that originate from each TAZ) for the TAZs. Eight passenger trip purposes are used in version 7 of FLSWM, including Home-Based Work (HBW), Home-Based Shopping (HBSH), Home-Based Other (HBO), Home-Based Social Recreation (HBSR), Non-Home Based (NHB), Truck-Taxi (TT), Long Distance Business (LDB) and Short Distance External-Internal or Internal-External (SDEI). Trip attractions (i.e., number of trips ending in each TAZ) for the five primary passenger trip purposes (i.e., HBW, HOSH, HBO, HBSR, and NHB), typically required for trip distribution by gravity models, are no longer modeled with version 7, because a destination choice model replaced the gravity model that was used for version 6 of FLSWM. The TT, SDEI, and LDB trip purposes still use the gravity model approach for trip distribution. The trip production for the four home-based trip purpose follows the cross-classification method, by which trip rates per dwelling unit vary by categories of number of autos per dwelling unit, number of persons per dwelling unit, and dwelling unit type (i.e., single family, multi-family and hotel-motel units). Table 3, Table 4, and Table 5 show home-based trip production rates for single- family, multi-family, and hotel/motel. For each TAZ in the model, specific weights are applied to estimate the numbers of households by household sizes (i.e., persons per household, from 1 to 5+) and auto ownership cross- classifications (i.e., 0 car, 1 car, 2+ cars). The estimated numbers are then multiplied with the corresponding trip generation rates in Table 3, Table 4, and Table 5 to obtain trip productions for the four home-based trip purposes (i.e., HBW, HBSW, HBSR, and HBO). Production for NHB for each TAZ is determined with the equation: and production for TT (Truk Taxi) with:

HBO).‌ Production for NHB for each TAZ is determined with the equation: NHB Productions = a * Commercial Employment + b * Service Employment + c * Dwelling Units (Eq. 1), and production for TT (Truk Taxi) with:: TT production = d * Total Employment + e * Dwelling Units (Eq. 2), where coefficients a, b, c, d, and e vary by counties. Attractions for TT for each TAZ are set to be equal to the productions. Passenger trip productions at the external stations are pre-determined with 2015 AADT data from FDOT. Trips produced from external stations can be either SDEI (i.e., less than 50 miles) or LDB (i.e., 50 miles and longer). The number of trips produced and the percentage of short distance trips for each of the 59 external stations are stored in a model input file (example shown in Table 6). SDEI trip productions from an external station is determined by the trip produced form that station times the percent of short distance trips for this station. LDB trip produced from this station is the total trip produced at this external station minus the SDEI trip produced. Table 6 shows an example of trip production data for 10 of the 59 external stations. 9479 10,362 95% SR 292 @ AL SL 11,000 Escambia 9480 18,488 90% US 98 @ AL SL 19,420 Escambia 9481 6,144 90% US 90 @ AL SL 6,635 Escambia 9482 35,768 75% I-10 @ AL SL 43,567 Escambia 9483 11,078 100% CR 184 @ AL SL 11,760 Escambia 9488 988 100% CR 89 @ AL SL 1,100 Santa ▇▇▇▇ 9489 2,758 100% SR 87 @ AL SL 3,203 Santa ▇▇▇▇ 9490 351 100% CR 191 @ AL SL 400 Santa ▇▇▇▇ 9491 13,039 100% CR 189 @ AL SL 14,328 Okaloosa 9492 676 100% CR 85A @ AL SL 700 Okaloosa For LDB trips produced from a TAZ within the state of Florida (i.e., internal TAZ), the productions are estimated with the equation:‌ LDB productions = 0.007342 * Total number of households in the TAZ (Eq. 3) The coefficient 0.007342 is the same as the version 6 of FLSWM.
