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

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 …

An Exploration Of Transportation Terrorist Stabbing Attacks, Brian Michael Jenkins, Bruce R. Butterworth, Jean-François Clair, Joseph R. Trella Iii

Mineta Transportation Institute

In his August 22, 2018 message to supporters of the Islamic State of Iraq and [greater] Syria (ISIS), Abu Bakr al-Baghdadi implored ISIS fighters in Syria and Iraq as well as those on various jihadist fronts in Africa, the Middle East, and Asia not to be dismayed by military setbacks suffered by the Islamic State, but to continue fighting, confident that Allah would ultimately reward those who remained steadfast with victory. In the same message, he exhorted homegrown jihadists abroad— “the fierce lions in the lands of the Cross—Canada, Europe, and elsewhere” to carry out simple attacks within their limited …

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

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.

The Success Of An Integrated Mobility Strategy: Lessons From The Netherlands For The Pacific West Coast, Lucas Van Der Linde

PSU Transportation Seminars

The Netherlands sets the standard for their multimodal connectivity. It has world's highest use of cycling and an integrated mobility network with an efficient transport system. During this seminar, Lucas will tell more about the Dutch Approach and how this could be applied to the American transportation context.

Lucas will use the case of the Bay area to show this. The Bay Area in California currently faces massive challenges in transportation because of the enormous growth of the region. With the use of a new innovative modelling tool, the Move Meter (http://www.movemeter.com/), Lucas will show the potential of …

Rethinking Streets For Bikes: An Evidencebased Guidebook, Marc Schlossberg, John Rowell, Roger Lindgren, Dave Amos

TREC Final Reports

This project is a follow up to a successful previous NITC project and subsequent nationally distributed book, called “Rethinking Streets: An Evidence-Based Guide to 25 Street Transformations.” The success of the first book demonstrated a need for easy access to evidence-based transportation information that can be used by practitioners, community members, policymakers, educators, and researchers. This project produced a follow-up guidebook, but with a focus on streets redesigned to accommodate bicycle transportation in ways following current best practices. Whereas the first book purposefully focused on “average” street retrofit projects to communicate the normalcy of such projects around the country, this …

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

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 …
