The research reviewed best practices, identified overrepresentations of serious crashes involving older drivers and pedestrians using Oregon crash data, and mapped the best practices and countermeasures. From 2013 to 2016, there were 884 older driver and 112 older pedestrian fatal and serious… Read More

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 Oregon Global Warming Commission found that carbon… Read More

Portland State University is a subcontractor on NCHRP 17-87 award to Kittelson & Associates, Inc: http://apps.trb.org/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=4373 Challenge Despite its prevalence as a transportation mode, walking receives less attention than the motor vehicle mode in terms… Read More

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' comprehension of bicycle-specific traffic signal faces. … Read More

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 the summer of 2019. The course will be geared… Read More

In the past decade, unmanned aerial vehicles (UAV) have become increasingly more popular in the commercial sector. Drones are being used for all kinds of purposes, such as surveillance, inspecting architecture, filming, wildlife research, and more. Freight delivery is a potential application that… Read More

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 Columbia and Willamette rivers and along the I-5… Read More

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 Portland’s Metro regional government to survey occupants… Read More

Data from travel surveys are used to forecast demand, inform transportation investments, and craft urban policies. Because these data are so essential to shaping our transportation system, it is critical that hard-to-reach populations—such as low-income, minority, and transit-dependent people—have… Read More

The interaction between transit vehicles and bicycles can create conflict when both share the same space. In particular, the location of transit stops poses specific challenges along bicycle facilities. Little research exists to offer insight on how the placement of transit stops affect bicycle… Read More

Human wayfinding and navigation are key organizing activities that allow human beings to acquire knowledge about the environment and develop cognitive representations in support of such essential tasks as route planning and travel. These activities are non-trivial in that they afford the activation… Read More
