  1. Advanced Modeling Practice at CMAP Kermit Wies October 2014

  2. Background and History

  3. Trip-Based Models

  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

  11. 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

  13. Activity-Based Models • Application of an Activity-Based Model for Highway Pricing Studies in Chicago • Transit Beyond Travel Time and Cost • Network Microsimulation Extension to Activity-Based Travel Model

  14. Highway Pricing Model http://www.cmap.illinois.gov/mobility/roads/congestion-pricing

  15. Transit Modernization Model

  16. Bike Model

  17. ABM/DTA Integration

  18. Advanced Modeling Practice at CMAP Kermit Wies October 2014
