So it is with cyclists. While many American cities have found effective ways to gauge motor vehicle traffic, whether through "car counters" or other means, almost none have done even a rudimentary, let alone an accurate, count of bicyclists. Worse yet, when we are counted, those tallies don't reflect where, when or for what purposes we ride. As an example, counts taken on bike lanes in central areas of cities will find commuters, while tallies taken on bike lanes leading out of those neighborhoods will find more recreational cyclists. And if a bike census, if you will, depends on counts from bike share docking stations, yet another type of rider will be found.
The problem is that jurisdictions that bother to count cyclists tend to use only one method to record riders. The most common is volunteers stationed, with a clipboard and pen, in places where significant numbers of people ride. I once was such a volunteer, for a day, with Transportation Alternatives: I stood on the Manhattan side of the Queensborough-59th Street Bridge and counted the cyclists and pedestrians (this was before motor scooters became popular) descending from its ramp to First Avenue. As diligent as I was, I am sure I missed riders or pedestrians. Even if my count were completely accurate, I had to wonder how useful it would have been for anything but deciding whether to widen the bike lane--which would never happen.
As Kea Wilson points out in a recent Streetsblog article, cities need not only to start counting cyclists; they also need to employ a number of methods, including devices like the "car counters" many already employ and data from sources like Strava and even cell phone data. Although they, together, won't count 100 percent of riders --sometimes mechanical and electronic counters stop working or, if they're programmed to detect a certain level of speed, miss a cyclist who's riding faster than a bus-- they will do much to make us less under-countednand, more important, mis-counted, than we are now.
Perhaps even more important, though, is a thoughtful analysis of the data collected. Why are cyclists riding (or not) where they're riding (or not)? Are they riding on one street rather than another, or instead of a nearby bike lane? What are some of our common destinations? Also, if a "census" is to be useful in improving bike safety, it needs to help in determining where crashes and injuries are most likely to occur.
Until cities and other jurisdictions start to make accurate counts of cyclists and assesments of how, where and why people ride (or don't), they won't build bicycle infrastructure or will continue to build more of the poorly-designed, -constructed and -maintained bike lanes we too often see.
