In recent years, there have been over 600 bicyclist fatalities annually in the United States. This sobering statistic has motivated a number of recent studies, including the recently released National Transportation Safety Board study, “Bicyclist Safety on US Roadways: Crash Risks and Countermeasures (PDF). ” That report notes that midblock crashes account for a disproportionate number of bicyclist fatalities and severe crashes, and that separated on-street bicycle facilities may reduce the likelihood of these crashes. However, there are only limited data on the safety outcomes of separated on-street bikeways in the U.S., despite their increasing popularity...

One of the most common locations for motor vehicle-bicyclist crashes is at controlled intersections. Particularly dangerous is the conflict between through bicyclists and turning drivers (either left or right). Despite widespread acknowledgement of this problem, transportation engineers and planners still lack definitive guidance on how to safely and effectively design for bicyclists at intersections in the United States.

In a newly contracted project, awarded to Toole Design Group by the National Cooperative Highway Research Program (NCHRP), a team of researchers will identify design best practices to reduce conflicts at intersections. In addition to Toole, the team includes researchers from Portland State University, Oregon State University (David Hurwitz), and Safe Streets Research & Consulting (Rebecca Sanders). Christopher...

Cyclists ride along a bicycle boulevard in Portland, Oregon

Wei Shi, Portland State University

In active transportation research, plenty of attention has been given to how different types of bike infrastructure affect people's likelihood of biking. Research has demonstrated that protected bike lanes encourage more people to bike than simple painted lanes, and that most cyclists feel safer riding through a protected intersection as opposed to navigating shared space with cars. However, relatively few empirical studies have investigated how holistically connected an entire bike network is, and how different populations can be positively or negatively impacted in their decision to bike by that level of connectivity.

Wei Shi, a recent Portland State University graduate with a PhD in urban planning, wrote her doctoral thesis on...

Economic and Business Outcomes of Bicycle and Pedestrian Improvements
Apr 22, 2020
 

PRESENTATION ARCHIVE

OVERVIEW

The National Street Improvements Study, conducted by PSU in conjunction with PeopleForBikes and consulting firm Bennett Midland, researched the economic effects of bicycle infrastructure on 14 corridors across six cities — Portland, Seattle, San Francisco, Memphis, Minneapolis and Indianapolis. The study found that improvements such as bicycle and pedestrian infrastructure had either positive or non-significant impacts on the local economy as measured through sales and employment. In this webinar, lead researcher Jenny Liu will share the results of the investigation and the unique methodology for investigating these economic outcomes.

THE RESEARCH

This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and the Summit Foundation, and conducted at Portland State University. Read more about the research: ...

OVERVIEW

The "Fast Track" project at the University of Oregon focuses on a mode of transportation that is sometimes left out of vehicle-to-infrastructure, or V2I, conversations: Bicycling. NITC researchers developed an app based on a new technology being integrated into modern cars: GLOSA, or Green Light Optimized Speed Advisory. GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a "green wave" so they won't have to stop at red lights.

This project demonstrates how GLOSA can be used by bicyclists in the same way it is used by motorists, with a test site on a busy car and bike corridor feeding the University of Oregon campus: 13th Avenue in Eugene, Oregon. Researchers developed a smartphone app that tells a cyclist whether they should adjust their speed to stay in tune with the signals and catch the next green. The project demonstrates how university researchers, city traffic engineers, and signal-controller manufacturers can come together to help bicyclists be active participants in a smart transportation system.

THE NEW PROJECT

Portland State University is embarking on a collaborative research effort, funded by the National Cooperative Highway Research Program (NCHRP), to help road users better understand bike-specific traffic signals. Over the next year, Dr. Christopher Monsere and Dr. Sirisha Kothuri of PSU's Transportation Research and Education Center (TREC) will work with researchers from Oregon State University and Toole Design Group to identify gaps in driver comprehension and causes of confusion when both bike signals and motor vehicle signals are present...

Prepared by TREC, the Federal Transit Administration (FTA) has just released a Manual on Pedestrian and Bicycle Connections to Transit.

TREC Director Jennifer Dill and TREC researcher Nathan McNeil worked with the FTA to develop the manual, a guidebook to creating a robust network for active transportation and transit users.

From defining "access sheds" to linking up transit and bike share, the newly published manual is a rich resource for planners and engineers looking to boost their city's bicycle and pedestrian transit access.

Dill and McNeil built the manual with a special...

The Federal Highway Administration issued an interim approval for bike signals, based on the NITC project "Operational Guidance for Bicycle-Specific Traffic Signals." The project, selected in 2015 as one of AASHTO's "Sweet Sixteen" high-value research projects, has been widely cited and the research is instrumental in beginning to standardize the use and design of bicycle signals.

This video provides a look at what that means for jurisdictions in the United States:
