Individuals using free-floating bike share leases in Seattle are carrying helmets sometimes, in accordance with a brand new evaluation carried out by College of Washington researchers. Solely 20 % of motorbike share riders wore helmets within the examine, whereas greater than 90 % of cyclists wore helmets whereas using their very own bikes.
Completely different analysis on the free-floating bike share techniques confirmed that bikes had been often obtainable in all Seattle neighborhoods throughout financial, racial and ethnic traces. Nevertheless, extra bikes had been situated in more-advantaged neighborhoods.
“There’s nowhere that was systematically ignored through the first six months of this system,” stated Stephen J. Mooney, an epidemiologist on the Harborview Damage Prevention & Analysis Middle and professor on the UW’s Faculty of Public Well being. He is the lead creator of each research.
The helmet examine exhibits that bike share riders could also be adopting an informal strategy to biking that does not embrace helmet utilization.
“What we’re involved about is: What are the implications of informal riders not carrying helmets?” Mooney stated. “What is the threat for them and for different folks?”
Researchers counted the variety of cyclists — noting helmet use -at 4 strategic places round Seattle: the Fremont bridge, the Burke-Gilman Path, Broadway Bike Lane and NW 58th Avenue at 22nd Avenue NW. Researchers discovered that just one in 5 folks using bike shares wore helmets.
Thus far, researchers have not seen a rise in head accidents amongst free-floating bike share riders, however they’re watching. It is essential to look at and higher perceive rider habits along with crash knowledge, Mooney stated. The methods folks journey free-floating bikes, and the place they journey them, and the way they fall from them after they crash might result in a really totally different threat profile than that of personal bike riders. Nonetheless, an awesome quantity of analysis exhibits that carrying a helmet helps to stop critical head harm in a motorcycle crash.
The researchers noticed fewer cyclists carrying helmets — each on non-public bikes and on bike share leases — in areas the place there have been plenty of bike shares.
The analysis discovering could also be a sign that the adoption of free-floating bike shares might help extra informal use, totally different from commuting or coaching, by which helmet use is much less a part of the tradition.
That is troubling, however not but trigger to take motion, Mooney stated.
“There’s plenty of nuance in bike security — we all know that helmets shield heads, however we additionally know that locations the place extra riders cluster often have decrease threat per rider. Clearly, we would like to see extra riders with helmets. However we acknowledge that not everybody needs to lug a helmet round simply in case they determine to journey casually later within the day. So we’re monitoring each ridership and accidents,” he stated.
Different research have discovered equally low statistics of motorbike helmet use in different bike share techniques, with about 15 % helmet use in New York and about 39 % in Boston in contrast with Seattle’s estimated 20 % use of helmets. Nevertheless, Vancouver’s system, Mobi, supplies helmets and boosts utilization there as a lot as thrice Seattle, at 64 %.
The helmet examine, revealed final month within the Journal of Group Well being, was co-authored by Bella Lee and Allyson O’Connor of the UW. Funding was supplied by a grant from the Eunice Kennedy Shiver Nationwide Institute for Baby Well being and Human Growth.
In a separate examine, revealed not too long ago within the Journal of Transport Geography, Mooney once more checked out bike share packages. This time the analysis staff wished to see if the advantages of motorbike share — akin to improved well being and decreased journey occasions — had been obtainable to all neighborhoods no matter financial standing, race and ethnicity.
“Free-floating bikes went in every single place. Just about everybody has some entry,” Mooney stated.
Prior research confirmed that docked bike share techniques, that are geographically constrained by station places, tended to favor advantaged neighborhoods. There weren’t stark variations in availability of the free-floating techniques, the analysis discovered.
Researchers used the combination knowledge collected from all of the free-floating bike share operators in Seattle and mixed that with neighborhood based mostly census knowledge. Whereas the distribution of motorbike shares was broad, they reported, there was a better focus of the leases in additional prosperous areas of the town.
“When you look a little bit bit deeper, there may be some inequity in the place the bikes go,” Mooney stated. “However bikes had been often obtainable all through the town.”
