TREC Project Briefs
In 1976, the Institute of Transportation Engineers (ITE) compiled their first Handbook of guidelines for evaluating development-level transportation impacts. Decades later, these methods are still ubiquitously used across the US and Canada. Only recently, with the third edition of the ITE Trip Generation Handbook, have new data and approaches been adopted. In this study NITC researcher Kristina Currans takes aim at understanding issues inherent in the collection and application of ITE’s data and methods in various urban contexts. This technology transfer guide touches on the main findings from this work.

TREC Final Reports
Building on the successful scientific computing training program offered by the Software Carpentry (http://www.software-carpentry.org/), this course exposes students to the best practices in data science through hands-on lab sessions. Using transportation data and examples, it also aims to help students tackle the challenge of “drinking from a hose” when dealing with the overwhelming amount of data that is increasingly common in transportation research and practice.
Although computing is now an integral part of every aspect of science and engineering, transportation research included, most students of science, engineering, and planning are never taught how to build, use, validate, and share software …

Transit travel time, operating speed and reliability all influence service attractiveness, operating cost and system efficiency. These metrics have a long-term impact on system effectiveness through a change in ridership. As part of its bus dispatch system (BDS), the Tri-County Metropolitan Transportation District of Oregon (TriMet) has been archiving automatic vehicle location (AVL) and automatic passenger count (APC) data for all bus trips at the stop level since 1997. In 2014, a new and higher-resolution bus AVL data collection system was fully implemented.
This new AVL system provides stop-level data as well as five-second resolution (5-SR) bus position data between …
Better Outcomes: Improving Accountability & Transparency In Transportation Decision-Making, Robert Zako, Rebecca Lewis
Better Outcomes: Improving Accountability & Transparency In Transportation Decision-Making, Robert Zako, Rebecca Lewis
TREC Final Reports
This report aims to help policymakers and staff at all levels of government make transportation investments that serve the public better.
Amazingly, we simply don’t know how effective government spending is at achieving the outcomes the public expects and has been promised! Clearly, taxpayer dollars buy roads, bus service, airports, ferry service, and other transportation facilities and services. But it is unclear how well such investments help get people where they want to go, create jobs, improve public health, support community development, and provide other benefits. In other words, it is uncertain how cost-effectively the means (transportation investments) achieve the …

Do People’S Perceptions Of Neighborhood Bikeability Match “Reality”?, Liang Ma, Jennifer Dill
Urban Studies and Planning Faculty Publications and Presentations
Do people perceive the built environment the same as we objectively measure it? If not, what are the relative roles of the objective versus the perceived environment on bicycling behavior? This study, based on data from Portland, Oregon, explored the match or mismatch between the objective and perceived bicycling environment and how it affects people’s bicycling behavior. The descriptive analysis indicated a fair agreement between perceived and objective measures. Older adults, women having children, less-educated and lower-income persons, and those who bicycle less tended to perceive their high-bikeable environment (measured objectively) as being a low-bikeable environment. In addition to the …
Community Attitudes Regarding Public Safety In Portland’S Parkrose Neighborhood, Kris R. Henning, Jason Jones, Christian Peterson
Community Attitudes Regarding Public Safety In Portland’S Parkrose Neighborhood, Kris R. Henning, Jason Jones, Christian Peterson
Criminology and Criminal Justice Faculty Publications and Presentations
The Portland Police Bureau (PPB) has partnered with Portland State University (PSU) to develop new strategies for improving public safety and police-community relations. The initiative seeks to provide residents with greater voice in where police work in their neighborhood and what steps the police take to address public safety concerns. The current report presents the findings from a household survey conducted in Portland's Parkrose neighborhood. Residents' top concerns were social disorder, property crime, and alcohol/drug use. The majority of residents surveyed reported that overall safety in the neighborhood had declined over the past 12 months and a significant proportion (63%) …
Impact Of Last Mile Parking Availability On Commercial Vehicle Costs And Operations, Miguel Figliozzi, Chawalit Tipagornwong
Impact Of Last Mile Parking Availability On Commercial Vehicle Costs And Operations, Miguel Figliozzi, Chawalit Tipagornwong
Civil and Environmental Engineering Faculty Publications and Presentations
This research analyses how parking availability levels affect commercial vehicle parking costs and operations in congested urban areas. Unlike passenger vehicles, parking availability has an impact on route characteristics and commercial vehicle fleet sizes. Hence, commercial vehicles parking costs cannot be captured solely by estimating delays and/or the cost of parking fines. This research combines logistics, queuing, and optimization models to study the impact of last mile parking availability on commercial vehicle costs and operations. Scenarios are built to study the impact of parking availability on typical less-than-truckload (LTL) and courier service costs. Results indicate that parking availability levels do …

Issues In Trip Generation Methods For Transportation Impact Estimation Of Land Use Development: A Review And Discussion Of The State-Of-The-Art Approaches, Kristina Marie Currans
Civil and Environmental Engineering Faculty Publications and Presentations
As agencies develop more robust planning objectives for creating sustainable and livable communities, the research community has continued developing supportive tools and methods to provide more accurate and robust means for estimating transportation impacts for site-level development review. This paper is a review of the state-of-the-art trip generation methods for land use transportation impact estimation. First, it provides an overview of the more recent available and peer-reviewed estimation methods. Second, the authors offer a discussion of the successes of state-of-the-art approaches using common themes of research to identify corresponding consistency with theories of travel behavior and urban economics. These themes …
Accessibility, Income, And Person Trip Generation: Multilevel Model Of Activity At Food Retail Establishments In Portland, Oregon, Kristina Marie Currans, Kelly Clifton
Accessibility, Income, And Person Trip Generation: Multilevel Model Of Activity At Food Retail Establishments In Portland, Oregon, Kristina Marie Currans, Kelly Clifton
Civil and Environmental Engineering Faculty Publications and Presentations
In the past decade, the methods for estimating multimodal transportation impacts of urban land use development have improved substantially. One assumption commonly made in these new methods is that overall person-trip rates at similarly-sized establishments of the same land use do not vary across a region. This is an assumption of convenience to permit the adjustment of ITE Trip Generation vehicle trip rates for use in different urban environments. However, this assumption is inconsistent with theories of urban economics, which recognize that businesses pay a premium to locate in areas with high levels of accessibility to attract more customers. In …

To develop and apply goals for future sustainability, we must consider what people care about and what motivates them to engage in solving sustainability issues. Sense of place theory and methods provide a rich source of insights that, like the socialecological systems perspective, assume an interconnected social and biophysical reality. However, these fields of research are only recently beginning to converge, and we see great potential for further engagement. Here, we present an approach and conceptual tools for how the sense of place perspective can contribute to social-ecological systems research. A brief review focuses on two areas where relation to …
