Research Highlights

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

Understanding the Transit-Dependent Population

Jennifer Dill

Public transit in metropolitan areas serves multiple and sometimes competing objectives. Increased attention on "choice" riders and transit as an economic development tool has shifted resources towards suburb-serving rail systems at the expense of inner-city bus service. This investment strategy may be at odds with the social service role that transit plays in providing mobility to those without other transportation options. However, there is a lack of research on the "transit-dependent"popul... Read More
