Proponents of advanced bikeways will point out a growing body of research on these facilities’ safety and benefits for cycling. They can now add another benefit: higher home values.

Research led by Jenny Liu of Portland State University looked at property around advanced bikeways in Portland, defined as bicycle boulevards, protected bike lanes and buffered bike lanes. She found positive effects on property values close to one of these bikeways and an even stronger effect where the network was denser.

Liu presents her research Wednesday at the annual meeting of the Transportation Research Board in Washington, D.C. Learn more or download the research paper.

For single family home sales, being a quarter mile closer to an advanced bikeway translated to a $686 premium, while increasing the density by a quarter mile represented a $4,039 premium. For multi-family homes, the effect of being close to a bikeway wasn’t statistically significant on sale price, but increasing the density of bikeways translated to $4,712 of value.

The research can inform policymakers who may question how much residents value bikeways and provide insight into siting decisions. “My results don’t necessarily say to put one here or not, but it does show there is indeed a...

Protected bicycle lanes have gained popularity as a safer way to get more people cycling. Earlier research from the Transportation Research and Education Center, TREC, at Portland State University showed that people feel safer in lanes with a physical barrier between bicycle and motor vehicle traffic.

The research hadn’t closely studied the intersections, where the barriers—and the protection they offer—go away. With little research guidance, agencies across the country could face the prospect of using untested approaches or avoiding protected lanes altogether.

TREC, through its National Institute for Transportation and Communities pooled-fund program, is now addressing intersections for protected lanes. The program lets agencies and interested partners invest small amounts to join research with a national impact. For this project, 11 partners each put $5,000 to $50,000 toward the $250,000 cost.

The project will help agencies decide which intersection treatments to use in which cases, and what elements each should include. Toole Design Group will work with the Portland State research team to tailor the results to practitioners.

By Jennifer Dill, TREC director.

I recently completed a national poll of people living in urban areas in conjunction with the National Association of Realtors® on Community and Transportation Preferences. The overall results are posted here. The survey included 3,000 adults living in the 50 largest urban areas in the U.S. (That includes suburban areas, as well as denser urban cores.) Here are some highlights related to bicycling.

1.    Less than one in five people have biked in the past month.

Overall, 72% of the adults surveyed said they were physically able and know how to ride a bike. Of those, 25% had ridden in the past month. (The survey was conducted in mid-May, so weather was reasonable.) That means only about 18% of adults in these urban areas biked recently. Most of the people who had biked, rode only for exercise (60%, or 15% of those who are able to bike), while the others (40%, or 10% of those who are able to bike) made at least some bike trips for transportation, such as to work, school, shopping, etc.
Note: From here on I will be focusing only on those people who are physically able and know how to ride a bike.

2.    There are gender and generational gaps.

This isn’t a big surprise, but women were less likely to bike than men,...

Bicycle and pedestrian safety has emerged as a top priority for U.S. Transportation Secretary Anthony Foxx and the Department of Transportation. With this in mind, the department’s top research official visited Portland State University, home to the U.S. DOT-designated national center for livable communities.

Greg Winfree, the assistant secretary for research and technology, visited Portland State’s transportation research and education center June 13. Center Director Jennifer Dill and researcher Christopher Monsere gave Winfree a tour of the center’s living laboratory: Portland’s active transportation infrastructure.

Winfree, an advocate for improving safety for vulnerable road users, explored the city’s various bicycle safety efforts, including bike boulevards, protected bike lanes, bike boxes, bike-specific signals and signage. He also learned of pedestrian research involving traffic signals, crossings and modeling

The tour highlighted research projects funded through U.S. DOT’...
