  3. Model Structure Highway Network • Freight Model • Trip Generation • Trip Distribution • Mode Choice • Passenger Model • Trip Generation • Trip Distribution • Auto Occupancy Joint Assignment

  4. Freight Model Statewide Zonal Socioeconomic Data Passenger Model Non-Freight Trucks Freight Trucks Statewide Highway Network Tonnage Generation by Commodity Group QRFM Trip Generation by Truck Class Auto Trip Generation from MPO Models Auto Trip Generation for Non-MPO Zones Auto Vehicle Trip Distribution Statewide Highway Network Skims QRFM Trip Distribution by Truck Class Tonnage Distribution by Commodity Group Tonnage Mode Choice (Tons to Trucks Conversion) Auto Occupancy Model Long Distance Trip Module Urban & Rural Auto Trip Table Freight Truck Trip Table Heavy Truck Trip Table Medium Truck Trip Table Light Truck Trip Table Short Dist.

  7. User Interface (Cont’d)

  8. Highway Network – In-State In-State: 87,853 Links

  9. Highway Network – Out-of-State In-State: 87,853 Links Out-of-State: 2,914 Links Total: 90,767 Links

  10. TAZ Structure - Internal Urban: 3,529 Zones Rural: 358 Zones

  11. TAZ Structure – Ext. Stations Urban: 3,529 Zones Rural: 358 Zones External: 94 Stations Total: 4,008 Zones

  12. Passenger Trips • Short Distance Trips Trip distance <= 40 miles • Long Distance Trips Trip distance > 40 miles

  13. Passenger Trip Purposes • Short Distance Trips • Home-Based Work • Home-Based Shopping • Home-Based Social-Recreational • Home-Based Other • Non-Home Based • External – Internal (EI)

  14. Passenger Trip Purposes • Long Distance Trips • Long Distance Business Trips • US Visitors to Florida • Florida Visitors to US • Canadian Visitors to Florida • Florida Instate Tourists • Data Sources for Long Distance Trips • National Household Travel Survey (NHTS) • American Travel Survey (ATS) • Florida Visitors Study

  15. Truck Trips • Separate Programs for Freight and Non-Freight Trips • Freight Trips • 14 commodity groups (trip purposes) • Tonnages of commodities (trip ends) • function of employment & population

  16. 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 Commodity Groups

  17. 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. 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
