Examining the Geotechnical Earthquake Hazard to Transportation Assets in Oregon and Washington: Characterizing Earthquake-Induced Deformations of Silt Soils

Principal Investigator: Diane Moug

Critical transportation infrastructure in Washington and Oregon is vulnerable to damage during strong earthquake shaking, including the anticipated magnitude 9 Cascadia Subduction Zone event. A major hazard to transportation infrastructure is the fai ... Read More

Expanding Transmobilities: An Art-Informed Methodology For Genderdiverse Travel Behavior

Principal Investigator: Nicholas Puczkowskyj

There is a significant gendered travel behavior research gap in the transportation literature. A plethora of transportation literature identifying and contrasting cisgender disparities exists, but more inclusive approaches to genderdiverse identities ... Read More

Subcontract: NCHRP 15-73 Design Options to Reduce Turning Motor Vehicle – Bicycle Conflicts at Controlled Intersections

Principal Investigator: Christopher Monsere

Co-Investigators: Sirisha Kothuri , Nathan McNeil

BACKGROUND One of the most common locations for fatal motor vehicle-bicyclist crashes is at intersections, which inherently have a large number of turning conflicts. Reducing these conflicts is a key objective in improving intersection safety acr ... Read More

Subcontract: NCHRP 15-74 Safety Evaluation of On-Street Bicycle Facility Design Features

Principal Investigator: Christopher Monsere

Co-Investigator: Sirisha Kothuri

https://apps.trb.org/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=4763 BACKGROUND While non-separated on-street bicycle facilities have been used in the United States for many years, separated on-street bicycle facilities are becoming increasing ... Read More

Communicating Research through Comics: Transportation and Land Development

Principal Investigator: Kelly Clifton

Co-Investigator: Kristina Currans

This project created a transportation comic, "Moving From Cars To People," which offers a succinct and fun introduction to a complicated topic: namely, how the built environment in the United States came to be designed for cars and what we can do abo ... Read More

Access to Opportunities: Redefining Planning Methods and Measures for Disadvantaged Populations

Principal Investigator: Arlie Adkins

Co-Investigator: Stephen Mattingly

This project will be made up of two separate studies that together will investigate areas where transportation planning and engineering can better serve disadvantaged and underserved communities. An interdisciplinary team of planning and public healt ... Read More

Resilient and Rapid Repair Measures for Seismically Vulnerable Bridges Following Major Earthquakes

Principal Investigator: Peter Dusicka

The Cascadia Subduction Zone (CSZ) earthquake threatens bridges across the Pacific Northwest. Damage is expected to be geographically spread throughout the region and will have a nearly simultaneous impact on transportation through several important ... Read More

Policy Implications of ORS 366.514 -- The Oregon Bike Bill

Principal Investigator: Hau Hagedorn

Driving is ubiquitous, convenient, and the default transportation mode choice for most Americans. While driving is convenient and efficient, vehicle emissions contribute to significant congestion and high concentrations of greenhouse gases. The Orego ... Read More

Road User Understanding of Bicycle Signal Faces on Traffic Signals

Principal Investigator: Christopher Monsere

Co-Investigator: Sirisha Kothuri

The latest report from the National Cooperative Highway Research Program (NCHRP), “Road User Understanding of Bicycle Signal Faces on Traffic Signals” (20-07/Task 420), zeroes in on some key gaps in research and practice around road users' compre ... Read More

S.T.E.A.M. TRAINing: Engaging High School Girls in Transportation and Equity Issues through GIS

Principal Investigator: Randy Morris

Co-Investigator: Nancee Hunter

The Institute of Portland Metropolitan Studies’ Community Geography program wishes to apply for a grant to develop the curriculum for a 1-2 week lab course in transportation-focused mapping and Geographic Information Systems (GIS), to be held in th ... Read More

Revisiting TODs: How Subsequent Development Affects the Travel Behavior of Residents in Existing Transit-Oriented Developments

Principal Investigator: Nathan McNeil

Co-Investigator: Jennifer Dill

Does living in a transit-oriented development (TOD) actually change the way people travel? That's the fundamental question that 15 years of research in Portland, Oregon seeks to answer. Since 2005, Portland State University has worked with Portlan ... Read More

Effects of Earthquake-Induced Liquefaction on Bridge Foundations and Transportation Network Using CDSS

Principal Investigator: Arash Khosravifar

A magnitude 9.0 earthquake by the Cascadia Subduction Zone (CSZ) is believed to be capable of causing widespread soil liquefaction in the Pacific Northwest (PACNW). Affected infrastructures include highway bridges specifically the ones crossing the C ... Read More
