Bike research leading to smarter regional investments, easier rides
When policymakers look to meet cycling goals by investing in new bicycle routes, they have little research to help them determine whether cyclists will actually use them. As a result, bicycle facilities aren’t considered equally with motor vehicle infrastructure.
That’s changing, thanks in part to OTREC research. An OTREC-funded study, the first to gather large-scale data that reveal cyclists’ actual route preference, is being published in a scientific journal (Transportation Research Part A). The findings have already been incorporated into the regional travel demand model used to make transportation investment decisions across the Portland region.
In the study, Portland State University researchers Joseph Broach, Jennifer Dill and John Gliebe (Gliebe is now with RSG Inc.) outfitted cyclists with GPS units to record which routes they chose and model the choices to reveal preferences. Previous studies have relied on stated preference surveys or less reliable methods of determining cyclists’ actual routes. The data gathering was supported by a grant from the Robert Wood Johnson Foundation through its national program Active Living Research.
The research determined not only the attractiveness of bike lanes, paths and bike boulevards, but also the effect of intersection design, turns and slope—factors that proved to be as important as the bike facility itself. While some assume that cyclists take the most direct route to any destination, the research found that cyclists take significant detours to use separated bike paths and bike boulevards. The study is the first to examine bike boulevards, the low-traffic neighborhood streets tailored for cycling.
Some findings are below:
