The “20-minute neighborhood” is often thought of as a place wherein daily needs can be met within a walkable area. With Portland‟s recently adopted goal of increasing bicycle ridership to a 25% mode share by the year 2030, efforts to incorporate bicycles into this concept will become increasingly important. However, limited research has examined the mix of physical infrastructure and land uses that constitute a “bikeable” neighborhood or community.
This paper explores a methodology for assessing a neighborhood‟s bikeability based on its mix of infrastructure and destinations – essentially the 20-minute neighborhood for bicycles. The area of outer east Portland, an area east of 82nd Avenue with substantially lower bicycling rates than other Portland neighborhoods, is used as a case study and compared to an assessment of neighborhoods that are considered to be bike-friendly (downtown, inner-east and north Portland). The paper examines prior approaches to assessing bikeability, details a new method to measure bikeability, presents the findings, and explores what impact expected or potential transportation and land use changes might have on bikeability.
