Plan for Advanced Modeling at CMAP Policy priorities Data needs Computing environment Freight Highway Pricing Transit Modernization

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

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

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

Mesoscale Model: step by step cmap.illinois.gov/catmug

CMAP Implementation Testing model execution Understanding new concepts Linking to standard procedures Results Validation

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

Forecasting Agent-based Economic Extension – External infrastructure decisions, economic change, policy actions – Combined effect of independent procurement and logistics business decisions
