Passenger Trips

Short Distance TripsTrip distance <= 40 miles

Long Distance TripsTrip distance > 40 miles

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)

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

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

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

Florida Department of Transportation 17

Freight Modes

Five Modes– Truck– Intermodal Rail– Carload Rail– Air– Water

Allocate by Commodity GroupAssume 306 Working Days per Year

Florida Department of Transportation 18

Non-Freight Truck Trips

Quick Response Freight Manual (QRFM) Method

Function of Employment & HouseholdThree Truck Types

– Light trucks (four-tired vehicles)– Medium trucks (single unit trucks with 6+ tires)– Heavy trucks (combination trucks)

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

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

Model Calibration/Validation

Validated to Year 2000 ConditionsThree Levels of Validation

– System-wide Achieve reasonable results statewide

– District-wide Adjustment of parameters specific to districts

– Corridor level Focus on major statewide corridors
