Research Highlights
Understanding Economic and Business Impacts of Street Improvements for Bicycle and Pedestrian Mobility - A Multi-City Multi-Approach Exploration [Phase 2]
Jenny Liu
This research project explores the economic impacts of bicycle and pedestrian street improvements in the United States using multiple data sources and analytical approaches. Building on studies in New York City and San Francisco, researchers examined before-and-after data for street improvements on 14 corridors in six cities: Indianapolis, Memphis, Minneapolis, Portland (OR), San Francisco, and Seattle.
WHY DO THIS STUDY
To make cities more livable and in response to growing concerns over...

Land Use and Transportation Policies for a Sustainable Future with Autonomous Vehicles: Scenario Analysis with Simulations
Liming Wang
Yao-Jan Wu
Even though there are tremendous uncertainties in the timing and evolution path of the Autonomous Vehicles (AV) technology, it may become a likely reality within most MPOs' long-range regional transportation plan horizon of twenty years. Yet a recent survey of largest MPOs in the US indicates only one of them "even mentions driverless, automated, or autonomous vehicles in its most recent RTP" (Guerra, 2016 page 211). One of the uncertainties in assessing the impacts of AV is their direction: ...
