Research Highlights
Real-Time Stochastic Matching Models for Freight Electronic Marketplace
Avinash Unnikrishnan
This grant from the National Science Foundation (NSF) will support research investigating how a real-time marketplace might be constructed to match freight shipments with available carriers. In such a system, freight shippers make a request to the system manager, and an automated service will match shipping jobs to carriers who are likely to accept them. The benefits of such a system include more efficient use of freight capacity (fewer empty miles) and reduced shipping prices, resulting in e...

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...
