Details of Event:
Adequate design, planning, and management of urban infrastructure require a deep understanding of the circulation of both people and goods throughout the system. The forecast of freight flows is a crucial element to well-informed infrastructure, economic, and environmental planning because of the significant inter-relationships between goods movement and congestion, air quality, supply chain management, demand for commodities, pavement management, labor, among others. Carrier operations, such as transloading of goods at a facility to reconsolidate or split shipments or shifting containers from one mode to another, are often inadequately modeled. In modeling practice, these operations tend to be ignored altogether. A number of new features are being studied for consideration in a statewide freight forecast model for California. Among these features, a transshipment-expanded network assignment model is presented that incorporates congestion in transshipment facilities and treats vehicles separately from commodities as cyclic flows. To calibrate the model systematically, a nonlinear programming network model based on inverse optimization is presented and shown to be solvable using classical nonlinear optimization methods without resorting to more complex complementarity methods. The discussion continues with extensions in adaptive/dynamic transportation network management and behavioral city logistics, and how those research directions promote the goals of improving safety, efficiency, accessibility, and sustainability of a region. A focus is placed on transportation agency management methods of a system of networked infrastructure that interacts with travelers and shippers who behave according to their individual agendas. The goal of the research program is to develop more robust and intelligent networked infrastructure systems, particularly in freight and transit, as well as adaptive and dynamic management methods and policies that can account for activity-based agendas.
