Florida Statewide Model
FLSWM is two models – a passenger model and a freight model.
Both use the same network and are blended in final assignment.

Trip Generation Rate Changes - Phase I Efforts
Previous trip generation based
on 17 regions
Now trip generation based on 67
areas (county level)
Florida Statewide Model
Freight Model Update - Phase I Efforts
• The only statewide commodities based model in
the US.
• The Florida Freight Supply-chain Intermodal
Model: FreightSIM is intended to:
– Support freight plan development
– Evaluate potential large scale infrastructure
investments
– Provide inputs to more detailed project level
evaluations
– Provide inputs to regional transportation planning
Florida Statewide Model
Freight Model Update - Phase I Efforts
• FreightSIM produces numerous outputs describing
freight system performance, including:
– Shipment movements by mode (road, rail, water, air), with
truck based shipments also converted to truck trips
– Commodity and truck zone to zone trip tables
– Loaded transportation networks, and derived measures,
e.g. vehicle miles traveled by functional class and area type
• The results are sensitive to many policy inputs and
change in the economy, including:
– Infrastructure Investments (highway system, ports)
– Tolls, user fees, or pricing
– Growth in employment and productivity by industry
Florida Statewide Model
Freight Model Update - Phase I Efforts
• FreightSIM is
multimodal and
captures import and
export movements as
well as domestic
freight
• Freight flows through
Florida’s deep sea
ports are represented,
for example those
through the Port of
Jacksonville
Example of model scenario results
showing truck volumes on Florida’s
highway system

Planned enhancements to
the FLSWM – Phase II
Phase scheduled to be
completed by 11/2015
Florida Statewide Model
Planned enhancements to the FLSWM – Phase II (And Beyond)
• Migrate to a full Navteq Network
• Incorporate Linear Reference System (LRS) into
model network
• Establish many-to-one process
• Increase database functionality
• Update to parcel level data
• Incorporate a toll choice model
• Add land use model and scenario interface
• Develop new local truck model
• Develop tourist trip model
Florida Statewide Model
Navteq Migration– Phase II
Advantages of Navteq Network
– Navteq more accurately reflects Florida’s road alignments
– Florida public agencies have access to Navteq through the state-wide
contract
– FDOT has placed its Linear Referencing System (LRS) on Navteq
– Every Navteq segment in the State Highway System or TranStat
basemap has a Roadway ID, Begin Mile Post, End Mile Post

•
Warehouse all necessary network
attributes in a database
•
Bring in the correct attributes and
model year into Cube for
processing
•
Output model attributes back to the
database for analysis and use by
others
•
Reduce model run times
(passenger model under 2 hours
with 8-core system)

Land Use Modeling Integration – Phase II
– Made possible by
• Migration to Navteq
• Use of parcel data
– Uses county control total
forecasts from other
agencies (i.e. BEBR)
– Allocates incremental land
use growth amounts within
the county based on
• Available land
• Accessibility
• Other variables
Florida Statewide Model
Phase III?
• Development of a light truck model based on truck surveys
• Toll Choice Model
– Develop toll choice within the mode choice phase
– Implement ramp-to-ramp tolling
• Tourist Model Development
– Need for tourist surveys

Future Use by MPOs
The Cube based Statewide model has the ability to extract
subareas from the Statewide model for use as a
standalone model.
Other agencies would have the ability to carve out network,
Attributes, land use, etc. for use in a smaller area model.
