8. State of the Practice Truck Models served us well but fall short in answering future freight planning needs Aggregated model – does not provide for detailed land use, infrastructure, community planning scenario analysis. Insensitive to agent-based economic scenarios, does not account for evolutionary developments of economic agents in the forecast, insensitive to fine-grained network changes. Does not include supply chain models and is not suitable for development of economic scenarios on mega-regional scale. Insensitive to mega-regional supply chain scenarios and technological shifts. Static model - does not provide for integration with dynamic traffic simulations, detailed safety analysis, and agent-based passenger travel demand models with continuous timeline. Trip-based – is not consistent with operational behavior of carriers and as a result insensitive to operational scenarios or relevant network improvements. Does not account for multi-modal aspect of supply chains, does not forecast multimodal freight flows and is not sensitive to multimodal freight issues. 10/23/20142014 AMPO Annual Conference8

10. SHRP2 C20 Guidance Strategic objectives of SHRP2-C20 project: Improve and expand the knowledge base Develop modeling methods to reflect actual supply chain management practices Develop modeling methods based on sound economic principles Maximize use of freight tools by public sector for planning and programming Improve availability and visibility of data between public and private sectors In order to achieve the above objectives, the following SHRP2 research initiatives will be addressed in this work: Establish techniques and standard practices to validate freight forecasts. Establish modeling approaches for “behavior-based” freight movement. Establish analytical approaches that describe how elements of the freight transportation system operate, perform, and impact the larger overall transportation system. Determine how economic, demographic, and other factors/conditions drive freight patterns and characteristics. Document economic and demographic changes related to freight choices. Advance research to effectively integrate logistics practices (private sector) with transportation policy, planning, and programming (public sector). 10/23/20142014 AMPO Annual Conference10
