Introduction
New modeling framework captures behavioral aspects of
freight agents
Captures Supply Chain and Logistics decisions of Firms
including Shippers, Carriers and Receivers
Framework includes Input-Output flow, Firm Synthesis,
Supply Chain and Logistics, Truck Tour and other sub-
models
Overall model provides detailed outputs by economic
sectors, industry class, temporal resolutions, etc.

Data Sources Typology
Trade Statistics provide data on the locations, quantity and value of production and consumption of internationally traded goods
National and Regional Accounts ( I/O tables) have detailed information on the flows of the goods and services across industry sectors along with location information when at a regional level
» Make and Use Table provide information about production and consumption, including of intermediate goods used in supply chains
Transportation Statistics provide information on modal equipment origins and destinations
6
Data Sources Typology
Consignment bills of lading information derived from data on shipment services via freight transportation services administrative records
Establishment surveys collect data about goods and modal equipment trips to/from surveyed business establishments identified by their industry
Commodity flow surveys collect detailed information about the mode, type and quantity of goods flowing across the network
Intercept surveys focus on collecting data about freight travel during the trip and focus on O/D information and equipment

Firm Synthesis
Key component of Financial Layer
Simulation of regional firms by
industry and by size
Data Requirement – Longitudinally
linked establishment level
database
Facilitates Establishment Life
Cycle Events : Births, Expansion,
In-migration, Dissolutions,
Contraction and Out-migration

Firm Synthesis – Diverse Data
Sources
Bureau of Economic Analysis (BEA) Input/Output Tables
County Business Patterns (CBP) data
Business Dynamics Statistics (BDS)

BEA Input Output Tables
Input-Output tables show how industries interact
These tables provide detailed information on how goods and services explain
the production process of industries
Four types of tables – Make, Use, Direct Requirements, Total Requirements;
Matrix of Industries and Commodities
Make Table – Shows commodities produced by each industry
Use Table – Shows inputs to industry production and commodities consumed by
final users
