Portland, Oregon, is one of the country's most bike-friendly cities, but in a recent survey of cyclists, bike riders say that the city could be doing more.
The study shows that 56 percent of the riders said they wanted to bike more but didn't because of "too much traffic." Thirty-seven percent cited a lack of nearby bike lanes and trails as their barrier. Those with a network of quiet streets near their home were more likely to ride regularly.
A second phase, to be completed this fall, will use Global Positioning System units to study the actual routes that riders take.
"For a large bike city, we have done an awful lot, but still cycling is an awful small share of all the travels that go on in this region," said Jennifer Dill, an associate professor at PSU's Nohad A. Toulan School of Urban Studies and Planning. "We're still far below some European cities; there's a lot more room for increase."
