Trip-Based Models Trip Generation Trip Distribution Mode Choice Network Assignment FeedbackTransit Non- Motorized Generalized Cost MSA
4
Plan for Advanced Modeling at CMAP Policy priorities Data needs Computing environment Freight Highway Pricing Transit Modernization
5
Advanced Freight Model Development GO TO 2040 Freight Chapter – National and Regional Policy – Economic development – Infrastructure Three-tiered freight analysis – Macro = Economic choice – Meso = Supply chain and logistics – Micro = Network operations Implementation strategy – Microsimulation – Agent-based
6
Progress-to-date Two rounds of mesoscale development – Microsimulates commodity flows and predicts distribution channels to, from and through the CMAP region. Also assembles local truck tours. Implemented at CMAP for scenario and project tests cmap.illinois.gov/catmug
7
Two rounds of development UIC Developed original FAME model at national level Designed the model and prepared the original code in SAS Extended the design and rewrote the code in R
8
Mesoscale Model: step by step cmap.illinois.gov/catmug
9
CMAP Implementation Testing model execution Understanding new concepts Linking to standard procedures Results Validation
10
Data Resources Basic demonstration uses currently available data: – Freight Analysis Framework – County Business Patterns – Make-Use Tables – Regional Model Data – National Freight Networks Parameter estimation: – heuristic – empirical

Recent Applications Tour Length Tonnage Comparison Circle Interchange
12
Forecasting Agent-based Economic Extension – External infrastructure decisions, economic change, policy actions – Combined effect of independent procurement and logistics business decisions
