V2x: Bringing Bikes Into The Mix, Stephen Fickas Mar 2019

V2x: Bringing Bikes Into The Mix, Stephen Fickas

TREC Final Reports

This project demonstrates how an inexpensive system (hardware and software) can add new functionality to existing signal controllers, giving bicyclists an efficient way to cross a controlled intersection. The system integrates three components: (1) a Bike Connect box that resides near the signal-controller and is connected to it, (2) an application that runs on a Bike Connect device (currently an iPhone) and requests a green light at the correct approach-distance, and (3) a cloud-based publish/subscribe (pub/sub) component that handles cellular-communication between phone app and box. One stumbling block for the project was a means to obtain reliable GPS data to …

New Pedestrian Modeling Tools: Growing Beyond The Portland Region, Kelly Clifton, Jamie Orrego-Onate, Patrick Allen Singleton, Robert J. Schneider

TREC Project Briefs

This project focuses on making our measures, models, and methods more transferable to other locations. Specifically, we re-evaluate, compare and test our pedestrian index of the environment (PIE) measure using data resources more commonly available to planning agencies across the country. Next, we test the results of PIE and its input data in models of pedestrian mode choice for stability of estimation results within a region (intraregional) and between regions (interregional). This research is the next logical step in the MoPeD’s enhancement and is critical to enabling its utility beyond the Portland region. The results of this project show that …


Regulatory Design For Transport Security Regulations Of Nuclear And Other Radioactive Material, Marc R. Fialkoff Mar 2019

Regulatory Design For Transport Security Regulations Of Nuclear And Other Radioactive Material, Marc R. Fialkoff

Purdue Workshop on Nonproliferation: Technology and Approaches

A cornerstone within a nuclear security regime of a country is a legislative and regulatory framework that both regulates the individuals using radioactive and nuclear materials, but also regulates the regulators for their commitments under International Law. When drafting nuclear law and regulations, both technical and legal expertise is needed to ensure the regulation meets the technical requirements for security, but also is legally enforceable within a country’s jurisdiction. While the Primary Nuclear Law, or Enabling Act provides establishes the Competent Authority and responsibilities for nuclear security, regulatory development is where the proverbial, rubber meets the road for requirements. The …

Odot Highway Cost Allocation Study Review: Challenges In Including Regional Revenues, Northwest Economic Research Center, Thomas Potiowsky, Emma Willingham, Katelyn Kelley, Devin Bales

Northwest Economic Research Center Publications and Reports

This report, written for the Oregon Department of Transportation (ODOT) by Portland State University’s Northwest Economic Research Center, outlines the challenges that regional revenue collection poses for ODOT’s biennial Highway Cost Allocation Study (HCAS). The HCAS assesses the relative burdens of light and heavy vehicle classes on state infrastructure, in relation to the amount of revenue that said vehicle classes generate. In other words, it ensures that light vehicles and heavy vehicles are “paying their share” of state transportation expenditures.

Differences in vehicle traffic or differential impacts to vehicle classes are the root cause of most of the problems that …

Webinar: Rethinking Streets For Bikes: An Evidence Based Guide Of Bike-Friendly Street Retrofits, Marc Schlossberg, Roger Lindgren

TREC Webinar Series

There is a growing demand for better infrastructure and fewer barriers to biking and other forms of space-efficient micromobility. Tackling daily trips by bike is easier on the environment, healthier for users and non-users alike, uses precious urbanized public and private land more efficiently, costs taxpayers less to build and maintain infrastructure, and when routes are safe and comfortable, moving by bike is also fun! Complete Streets policies are being adopted across the country, and there is an active conversation around the safety imperative of a Complete Streets approach. Yet, local officials often need both design guidance and the …


Webinar: Words Matter: Recognizing And Addressing Modal Assumptions To Shift Transportation Culture, Barb Chamberlain Feb 2019

Webinar: Words Matter: Recognizing And Addressing Modal Assumptions To Shift Transportation Culture, Barb Chamberlain

TREC Webinar Series

Search #DriverNotCar or #CrashNotAccident on Twitter and you’ll find a vigorous discussion about the power of word choices to shape our understanding of what happens on the street and who’s responsible. When we directly examine and discuss the language we use, we acknowledge its power both to reflect existing attitudes and to shape developing attitudes. This presentation will uncover embedded biases or assumptions in common transportation terminology and provide tips and tools to help us broaden our inclusion of everyone we are supposed to serve as transportation professionals.

From Knowledge To Practice: Rethinking Streets For People On Bikes, Marc Schlossberg, John Rowell, Roger Lindgren Feb 2019

From Knowledge To Practice: Rethinking Streets For People On Bikes, Marc Schlossberg, John Rowell, Roger Lindgren

TREC Project Briefs

For too long we’ve been building streets as though they have one function–to move cars quickly. The reality is that streets can to do more than just move cars. They can move people on foot, on bikes, on transit, without hurting vehicular throughput and safety. They can be more than a way to get somewhere else. Good streets are good places, too – public places where people meet, sit and socialize, conduct business, wander about, play, and more.


Attracting And Retaining Women In The Transportation Industry, Jodi Godfrey, Robert L. Bertini Feb 2019

Attracting And Retaining Women In The Transportation Industry, Jodi Godfrey, Robert L. Bertini

Mineta Transportation Institute

This study synthesized previously conducted research and identified additional research needed to attract, promote, and retain women in the transportation industry. This study will detail major findings and subsequent recommendations, based on the annotated bibliography, of the current atmosphere and the most successful ways to attract and retain young women in the transportation industry in the future. Oftentimes, it is perception that drives women away from the transportation industry, as communal goals are not emphasized in transportation. Men are attracted to agentic goals, whereas women tend to be more attracted to communal goals (Diekman et al., 2011). While this misalignment …

Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang Jan 2019

Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang

TREC Webinar Series

Although connected vehicles (CVs) will soon go beyond testbeds, CVs and human-driven vehicles (HVs) will co-exist over a long period. Hence, it is critical to consider the interactions between these two types of vehicles in traffic flow modeling. In this study, we aim to develop a macroscopic model to understand how CVs would impact HVs in the traffic stream. Grounded on the second-order traffic flow model, we study the relationships among flow, density, and speed by two sets of formulations for the groups of CVs and HVs, respectively. A set of friction factors, which indicate CVs' impact to HVs, are …

Schedule Creep: In Search Of An Uncongested Baseline Block Time By Examining Scheduled Flight Block Times Worldwide 1986–2016, Terence P. C. Fan

Research Collection Lee Kong Chian School Of Business

Based on a stratified random sampling of airlines’ schedules for 200 heavily travelled directional nonstop airport pairs, this paper examines systematically how scheduled block times in non-stop flights have changed from 1986 to 2016. Three econometric analyses, by way of a 10th percentile quantile regression, 15th percentile quantile regression and ordinary least-squares regression, show that after accounting for the effects of air traffic growth, airport-specific congestion, flight delays, number of seat per flight, aircraft type, flight heading, airport slot policy, other airport-specific anomalies, airline-specific policies and changes in crude oil price, scheduled block times have been growing at a pace …

The Changing Role Of Public-Private Partnerships In Urban Transportation: A Case Study Of The Rise Of P3s In Denver, Co, Sylvia Arriaga Brady

Electronic Theses and Dissertations

This research examines the expanding role of public-private partnerships (PPPs or P3s) in Denver metro transportation projects in three areas: (1) innovative funding and financing of transit infrastructure projects, (2) the partnerships between freight and passenger rail services, and (3) emerging collaborations of local governments, transit agencies, and transportation network companies (TNCs).

The purpose of the first study was to examine the recent use of P3s in the Denver Regional Transportation District's (RTD) FasTracks program, a 2004 voter-approved $4.7 billion transit expansion program. After a shortfall in funding, RTD partnered with several private consortia to enable the FasTracks program to …


Social Equity In Transit Service: Toward Social And Environmental Justice In Transportation, Torrey Lyons Jan 2019

Social Equity In Transit Service: Toward Social And Environmental Justice In Transportation, Torrey Lyons

TREC Theses and Dissertations

This dissertation explores social equity as it applies to public transportation. Transit has long been considered a tool to alleviate inequity by limiting the effects of spatial mismatch and providing access to opportunity to disadvantaged populations. This theory, however, has not been adequately proven empirically. The first chapter of this dissertation tests the theory that spatial mismatch is moderated by quality transit service. We do this by taking a cross section of the largest urban areas in the United States and applying structural equation modeling to identify relationships between exogenous and endogenous factors. We find that higher quality transit service …

The Resilient City: A Platform For Informed Decision-Making Process, Paul Niculescu-Mizil Gheorghe, Jarutpong Vasuthanasub, Adrian Gheorghe

Engineering Management & Systems Engineering Faculty Publications

As over half of the world’s inhabitants lives in metropolises, the rapid growth in urbanization has made cities becoming more and more exposed and vulnerable to a broad spectrum of threats and hazards. In order to respond to such difficulties, a concept of resilience is considered a significant component for the long-term planning and sustainable development of the cities. “Resilient City” is a new paradigm that challenges the idealistic principle of stability and resistance to change implicitly in sustainable development and success. However, building a resilient city requires a holistic approach, as well as the appropriate adoption of knowledge and …
