“The economic competitiveness of our state is directly linked to how, why and where our businesses move their goods. Understanding these freight movements enables us to target policies and resources at highway, rail, water, and air corridors that will improve the State’s competitive position.” - Elwyn Tinklenberg, MN DOT Commissioner of Transportation Wednesday, December 1, 201018 Source: 2000 MN DOT Statewide Multimodal Freight Flows Study

Factors affecting freight demand Economy (volume of goods produced vs. consumed) Industrial Location Patterns (spatial distribution) Globalization of Business Just-in-Time (JIT) Inventory Practices (Inventory and Production in sync) Centralized Warehousing (Increased use of 3PLs) Fuel Prices Truck Size & Weight Limits (Increased payload requires less trips and in return lowers operating costs) Congestion Technology Wednesday, December 1, 201022 Source: Quick Response Freight Manual. FHWA. 1996. pp. 2-3 to 2-10.

Data Sources (many available….sort of! ) ▪ Carload Waybill Sample ▪ Commodity Flow Survey (CFS) ▪ Freight Analysis Framework (FAF) ▪ LTL Commodity and Market Flow Database ▪ National Transportation Statistics (NTS) Limitations ▪ Emphasis toward national and statewide ▪ Frequency of data ▪ Potential bias due to survey methods, unreliable estimates, or lack of freight modal coverage Wednesday, December 1, 201023

Traffic Assignment Preload with All-or-Nothing method Model Validation Many tests similar to auto model validation. Each step of process (Trip Gen, Distro,…etc) Compare observed data to modeled output Compute statistics…. ▪ And compare to other regions of similar size ▪ By varying levels of area type, geography, or truck type Scenario Tests & Performance Measures Wednesday, December 1, 201028
