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...Read more
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).

Amid the explosion of active transportation literature over the last thirty years, practitioners struggle to effectively synthesize and use that research in their everyday practice. The interdisciplinary scope is vast: engineering, health and medicine, planning and design, psychology, public administration and policy, and many more. The search tools to find the sprawl of active transportation research on any one topic are inadequate, particularly for the average user. Meanwhile, there are still gaps in our knowledge about active...Read more

The latest report from the National Cooperative Highway Research Program (NCHRP), “Road User Understanding of Bicycle Signal Faces on Traffic Signals” (20-07/Task 420), zeroes in on some key gaps in research and practice around road...Read more
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...Read more
