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 ac...

This strategy is incompatible with transit systems and ridership in nearly every transit market has plunged, causing agencies to reduce service levels to protect riders and employees. Still, mobility is required in many cities and the ability ...
