A right-hook crash is a crash between a right-turning motor vehicle and an adjacent through-moving bicycle. At signalized intersections, these crashes can occur during any portion of the green interval when conflicting bicycles and vehicles are moving concurrently. The objective of this research was to evaluate the effectiveness of four types of engineering countermeasures – regulatory signage, intersection pavement marking, smaller curb radius, and protected intersection design – at modifying driver behaviors that are known contributing factors in these crashes. This research focused on right-hook crashes that occur during the latter stage of the circular green indication at signalized intersections …

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 …

This report presents finding from research evaluating U.S. protected bicycle lanes (cycle tracks) in terms of their use, perception, benefits, and impacts. This research examines protected bicycle lanes in five cities: Austin, TX; Chicago, IL; Portland, OR; San Francisco, CA; and Washington, D.C., using video, surveys of intercepted bicyclists and nearby residents, and count data. A total of 168 hours were analyzed in this report where 16,393 bicyclists and 19,724 turning and merging vehicles were observed. These data were analyzed to assess actual behavior of bicyclists and motor vehicle drivers to determine how well each user type understands the design …
Pushing Pedalers: What Drives Bicycling?, Jennifer Dill, John Gliebe
Pushing Pedalers: What Drives Bicycling?, Jennifer Dill, John Gliebe
TREC Project Briefs
Using a bicycle instead of a motor vehicle for a portion of regular travel could increase people’s physical activity and help improve the nation’s health. Over 60% of personal trips are five miles or less – a reasonable distance to ride a bike – and nearly 40% are two miles or less. Yet current rates of bicycling for transportation are very low, despite the popularity of recreational cycling. Given the potential of bicycling as a means of everyday travel, why aren’t more people cycling? Very little information has been available on the relationship between different types of infrastructure, such as …

With rates of obesity, heart disease, and related health problems increasing in the U.S. many policy makers are looking for ways to increase physical activity in everyday life. Using a bicycle instead of a motor vehicle for a portion of everyday travel could help address these problems. This research aims to fill a gap in the existing literature on the effect of different types of infrastructure, such as bicycle lanes or paths, on bicycling. The project used global positioning system (GPS) technology to record where a sample of 164 adults in the Portland, OR region rode their bicycles. Data was …
