Dynamic Evaluation of Transportation Structures with iPod-Based Data Acquisition

Principal Investigator: Charles (C.J.) Riley

This grant supported coursework and laboratory development and expanded research capacity, promoting (a) innovative learning activities that expose students to cutting-edge methods of bridge structural health and behavior monitoring and (b) research ... Read More

Design for an Aging Population

Principal Investigator: Trygve Faste

Co-Investigator: Kiersten Muenchinger

Older Americans are increasing in numbers and addressing their needs through better public transportation design will improve their quality of life. This study sought to increase understanding of the obstacles faced by people with impairments in visi ... Read More

Establishing Graduate Certificates in Sustainable Transportation at US Universities & Colleges

Principal Investigator: Keith Bartholomew

Aside from cruising State Street on a Saturday night, transportation is not an objective in and of itself, but a means to carry out the functions of daily living, connecting us from where we are to where we need to be. Those functions, which are spat ... Read More

Generalized Adaptation of an Electric-Hydraulic hybrid drive system

Principal Investigator: James Long

Co-Investigators: Steve Edgeman , Xin Wang

KersTech Vehicle Systems is in the process of creating a hybrid drive system combining a flat format hydraulic motor with an electric motor for energy recapture of vehicle momentum. The initial drive system is targeted at a specific vehicle applicati ... Read More

Evaluation of an Eco-driving Intervention: Changing Knowledge, Attitudes, and Behavior by Means of Supervisor Support

Principal Investigator: Donald Truxillo

Co-Investigators: John MacArthur , Leslie Hammer , Talya N. Bauer

Past eco-driving research has looked at the effectiveness of various eco-driving programs, but the role supervisor and organizational support have remained unexamined. This is unfortunate, as support from the supervisor and the organization have cons ... Read More

Planning Ahead for Livable Communities Along the Powell-Division BRT: Neighborhood Conditions and Change

Principal Investigator: Lisa Bates

Co-Investigator: Aaron Golub

New transit investments can be a double-edged sword for disadvantaged communities (e.g. those included in environmental justice and Title VI potected classes). Transit investments improve community’s mobility and access and may improve health with ... Read More

Adding Value to GPS Travel Data with New Open-Source Processing Software for Everyone

Principal Investigator: Jennifer Dill

Researchers and practitioners have a growing interest in using Global Positioning System (GPS) based travel data to augment or even to replace traditional diary-based surveys. GPS data promise improved accuracy and more detailed spatial data. Largely ... Read More

Drivers’ Attitudes and Behaviors Toward Bicyclists: Intermodal Interactions and Implications for Road Safety

Principal Investigator: Tara Goddard

Psychology teaches us that implicit biases—attitudes we hold on a level below consciousness, and may not even be aware of—can have a heavy influence on split-second decisions. In a fast-paced activity like driving, with a lot of moving parts in a ... Read More

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Principal Investigator: Miguel Andres Figliozzi

Transportation corridors are complex systems. Tradeoffs, particularly in terms of traffic mobility, transit performance, accessibility and pedestrian interactions, are not well understood. When the focus is on motorized vehicle mobility and throughpu ... Read More

Pedestrian Modeling and Agent Cognition

Principal Investigator: Nicholas Perdue

Walking is one of the most commonplace forms of human expressions, yet the forms, motivations, and practices of walking vary greatly and are often at odds with dominant discourses in urban and transportation planning. As interest in pedestrianoriente ... Read More

Developing a model for Transit Oriented Development in Latino Immigrant Communities: A National Study of Equity and TOD

Principal Investigator: Gerardo Sandoval

Multimodal transportation and land use decisions have important effects on vulnerable low-income communities. TOD (transit oriented development) projects can encourage livability and help these communities by providing access to public transportation ... Read More

Measuring the Impacts of Social Media on Advancing Public Transit

Principal Investigator: Jenny Liu

Co-Investigator: (Jeff) Xuegang Ban

This project is a collaboration between Portland State University (PSU) and the Center for Infrastructure Transportation & Environment (CITE) at Rensselaer Polytechnic Institute seeking to develop performance measures for assessing the impacts of soc ... Read More
