Home-Based Shopping
Home-Based Social-Recreational
Home-Based Other
Non-Home Based
External – Internal (EI)

14. Passenger Trip Purposes

16. Commodity Groups Fourteen Groups Agriculture Non-Metallic Minerals
Coal
Food
Non-Durable Manufacturing Goods
Lumber
Chemicals
Paper
Petroleum Products
Other Durable Manufacturing Goods
Clay, Concrete and Glass
Waste
Miscellaneous Freight
Warehouse

17. Allocate by Commodity Group Assume 306 Working Days per Year
Freight Modes
Five Modes
Truck
Intermodal Rail
Carload Rail
Air
Water
Allocate by Commodity Group
Assume 306 Working Days per Year

18. Non-Freight Truck Trips
Quick Response Freight Manual (QRFM) Method
Function of Employment & Household
Three Truck Types
Light trucks (four-tired vehicles)
Medium trucks (single unit trucks with 6+ tires)
Heavy trucks (combination trucks)

19. Trucks are Converted to Passenger Car Equivalent (PCE)
Joint Trip Assignment
Trucks are Converted to Passenger Car Equivalent (PCE)
Multi-User-Class Equilibrium Trip Assignment
Long distance auto and heavy trucks are assigned to highway path based on free flow travel times
Short distance auto, medium- and light-trucks are assigned to highway path base on congested travel times

20. Joint Trip Assignment Post Processing
Change attribute names to make the output more readable
Convert PCEs back to number of trucks
Calculate aggregate statistics

21. Model Calibration/Validation
Validated to Year 2000 Conditions
Three Levels of Validation
System-wide
Achieve reasonable results statewide
District-wide
Adjustment of parameters specific to districts
Corridor level
Focus on major statewide corridors

22. Model Applications
Statewide Long- and Mid- Range Transportation Planning Studies
Florida’s Strategic Intermodal System (SIS) Implementation Analysis
Corridor Analysis
Freight Movements Analysis
Freight Mode Shift Impacts
Source of External Forecasts for Urban and Regional Models

23. Model Enhancements
Development of GIS Based Network
More Compatible TAZ Structure
Uniform Passenger Trip Generation Model
Review/Revise Freight Model
Update Long Distance and Tourist Trip Tables
Validate to 2005 Conditions
