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

Operational Analysis of Transit Bus Collisions

James Strathman
Many factors can influence bus crashes and other incidents. In this study, James Strathman of Portland State University sought to quantify the relationship between bus crashes and crash determinants in the Portland-area TriMet system using a spatially disaggregate, risk-based approach. Strathman examined 4,631 collision and non-collision incidents between 2006 and 2009 to determine how operator demographics, employment status, assignment characteristics, service delivery, performance indi...
