Understanding the Accessibility, Economic and Social Equity Impacts of Urban Greenway Infrastructure

Jenny Liu
“City Greenways” is a concept proposed as a part of Portland’s 2035 Comprehensive Plan, which calls for a citywide network of park-like pedestrian and bicycle friendly streets crisscrossing the city at roughly three-mile intervals. This research establishes several approaches to measure the transportation network impact of the “City Greenways” and relate bicycle network measures to economic and social equity outcomes. Expanding upon existing literature, we derived three sets of bicycle… Read More

Updating and Expanding LRT/BRT/SCT/CRT Data and Analysis

Arthur C. Nelson
This project will update and expand our station area databases (developed under previous NITC contracts 547, 650, and 763) to include new systems added since the late 2000s and more metropolitan areas. Under prior NITC contracts, we built station area databases for 12 light rail transit (LRT) systems, nine bus rapid transit (BRT) systems, four streetcar transit (SCT), and five commuter rail transit (CRT) systems. We included employment data extending annually from 2002 through 2011, and census… Read More
