Practical Approximations to Quantify the Impact of Time Windows and Delivery Sizes on Freight VMT in Urban Areas

Miguel Figliozzi
Supply chains and urban areas cannot thrive without the efficient movement of goods and accessibility to services. Commercial vehicle flows and VMT are the ultimate materialization of supply chain activities in the public road network (Figliozzi, 2006). From a freight planning perspective, it is crucial to understand and quantify how routes and distribution decisions translate into commercial VMT. A recent study indicates that commercial vehicles carrying goods or providing services acco... Read More

A Novel Design Strategy for Integrating Freight Rail Into Urban Settings: A Capping Study

John Schnabel
This investigation seeks to explore specific design solutions that could potentially enhance the capabilities of heavy rail facilities while increasing their safety and reducing their environmental and community impacts. Using Portland's Brooklyn Rail Yard as the study site, this research would explore the potential of structural platforms (caps) built above the existing rail yards to provide development space for expanding rail capacity and rail related activities. The potential for capp... Read More
