Portland has faced a mass displacement of Black households from the historically segregated area of Albina through various phases of urban renewal, urban deterioration, and gentrification. A substantial number of them have moved to East Portland, a s ... Read More

Land Use and Transportation Policies for a Sustainable Future with Autonomous Vehicles: Scenario Analysis with Simulations

Principal Investigator: Liming Wang

Co-Investigator: 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 ... Read More

Bicycle Detection and Feedback Assessment

Principal Investigator: Christopher Monsere

Co-Investigators: David Hurwitz , Sirisha Kothuri

Bicycling is increasing in the United States -- the number of trips made by bicycle more than doubled from 1.7 billion trips in 2001 to 4 billion in 2009 (National Household Travel Survey, 2009). With the increase in bicycling rates, there is a criti ... Read More

Addressing Oregon’s Rise in Deaths and Serious Injuries for Senior Drivers and Pedestrians

Principal Investigator: Christopher Monsere

Co-Investigators: Sirisha Kothuri , Jason Anderson , David Hurwitz
