This document outlines the advanced modeling practices implemented at the Chicago Metropolitan Agency for Planning (CMAP) as discussed by Kermit Wies in October 2014. It covers the historical background of trip-based modeling, the integration of freight analysis, economic development, and infrastructure strategies. The three-tiered freight analysis—macro, meso, and micro-levels—along with microsimulation and agent-based modeling techniques are highlighted. Additionally, the implementation strategies for activity-based models in highway pricing and transit modernization are addressed, showcasing practical applications and results validation using current data.

Advanced Modeling Practice at CMAP Kermit Wies October 2014
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
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
