For a number of reasons (congestion, public health, greenhouse gas emissions, energy use, demographic shifts, and community livability to name a few), the importance of walking and bicycling as transportation options will likely continue to increase. Currently, policy interest and infrastructure… Read More

This research will develop a realistic installation guideline that supports the requirements of advance traffic signal controller operations, hybrid detection installations, and non-invasive detection optimization. This guideline shall provide prototypical detection configurations and new timing… Read More

Research questions include: How does intersection sight distance (ISD) impact crashes? How can temporal variations in ISD (e.g., foliage) be quantified? Should quality of ISD and the presence of objects to judge depth perception be considered? How does the roadway and traffic affect the… Read More

The overall goal of the proposed research is to quantify the safety performance of alternative traffic control strategies to mitigate right-turning vehicle-bicycle crashes at intersections in Oregon. Read More

Racial minorities are disproportionately represented in pedestrian traffic fatalities, indicating a significant public health and safety issue. Psychological and social identity-related factors have previously been shown to influence drivers’ behaviors toward pedestrians. If drivers’ behavior… Read More

The objective of the project is to evaluate the effectiveness and efficiency of non-emergency medical transportation services (NEMT). The first objective of this project was to design a framework that could be used to evaluate the effectiveness and efficiency of non-emergency transportation… Read More

The objective of the research is to develop more reliable ways to assess signalized intersection safety in Oregon so that ODOT and other agencies can allocate funding resources towards effective intersection safety configurations for both new and existing facilities. This will be accomplished by… Read More

Public transit in metropolitan areas serves multiple and sometimes competing objectives. Increased attention on "choice" riders and transit as an economic development tool has shifted resources towards suburb-serving rail systems at the expense of inner-city bus service. This investment strategy… Read More

The purpose of this project was to evaluate the effects of new bicycle boulevards in Portland, OR on physical activity for recreation and transportation for families with children. Data was collected pre- and post-boulevards, roughly one year apart. Objective physical activity data was collected… Read More

To understand the impact of daily travel on personal and societal well-being, researchers are developing measurement techniques that go beyond satisfaction-based measures of travel. Metrics related Subjective Well-Being (SWB), defined as an evaluation of one’s happiness or life satisfaction, are… Read More

Buckling restrained brace (BRB) is a structural component that has been developed to provide known and repeatable strength in both tension and compression. Over the last couple ofdecades, BRBs have seen broad adoption in buildings in areas ofmoderate to high seismicity due to their predictable… Read More

Economical, ecological, and safe driving – eco-driving – is aimed at reducing fuel consumption and greenhouse gas emissions (Martin, Chan, & Shaheen, 2012). The adoption of energy-efficient driving styles and practices has been recognized as a means of reducing energy consumption, and estimates of… Read More
