NSF SCC RAPID: Consumer Responses to Household Provisioning During COVID-19 Crisis and Recovery

Kelly Clifton Rebecca Lewis
When the COVID-19 pandemic first swept across North America and led to emergency shutdowns during the spring of 2020, the way people acquired food and household necessities was dramatically impacted.

This NSF SCC RAPID grant supported the data collection for this research. See the related NITC grant: https://trec.pdx.edu/research/project… Read More

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: on… Read More
