6 Florida Department of Transportation 6 User Interface

7 Florida Department of Transportation 7 User Interface (Contd)

8 Florida Department of Transportation 8 Highway Network – In-State In-State:87,853 Links

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

10 Florida Department of Transportation 10 TAZ Structure - Internal Urban:3,529 Zones Rural: 358 Zones

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

12 Florida Department of Transportation 12 Passenger Trips Short Distance Trips Trip distance <= 40 miles Long Distance Trips Trip distance > 40 miles

13 Florida Department of Transportation 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 Florida Department of Transportation 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 Florida Department of Transportation 15 Separate Programs for Freight and Non-Freight Trips Freight Trips –14 commodity groups (trip purposes) –Tonnages of commodities (trip ends) –function of employment & population Truck Trips

16 Florida Department of Transportation 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 Florida Department of Transportation 17 Freight Modes Five Modes –Truck –Intermodal Rail –Carload Rail –Air –Water Allocate by Commodity Group Assume 306 Working Days per Year

18 Florida Department of Transportation 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 Florida Department of Transportation 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 Florida Department of Transportation 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 Florida Department of Transportation 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 Florida Department of Transportation 22 Model Applications Statewide Long- and Mid- Range Transportation Planning Studies Floridas 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 Florida Department of Transportation 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

24 Florida Department of Transportation How to Get the FLSWM? 24

25 Questions?
