Strong opening statements from @NTSB: "preventing a crash from happening in the first place is our top priority." and "If we do not improve roadway infrastructure for bicyclists, bicyclists will die who otherwise would not."
@NTSB Why is @NTSB doing this Bicycle Safety Report? According to @NHTSAgov , 806 bicyclists died in crashes with motor vehicles in 2017. ... and it has been 47 years since the @NTSB examined bicyclist safety
@NTSB @NHTSAgov In 2008 the @CDCgov @CDCChronic @CDCEnvironment set a healthy people 2020 goal for the bicyclist fatality rate at 0.22 deaths per 100,000 people. Since then the bicyclist fatality rate has increased and reached .26 deaths per 100k in 2016
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment The @NTSB found that most people were killed while biking by people driving who were overtaking them mid-block.
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment A person bicycling was 65% more likely to die or sustain a serious injury where the posted speed limit was 30-35 mph compared to roads signed for 25 mph or less #safetyoverspeed #speedkills
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment Protected bike lanes can reduce and/or mitigate these dangerous crashes, but they must be well designed - including at intersections. As @IIHS_autosafety said earlier this year, we need higher design standards for #protectedbikelanes iihs.org/news/detail/so…
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety Better bike infrastructure needs to include better intersection treatments, as @NACTO provides guidance on nacto.org/publication/ur…
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO According to @NTSB "effective infrastructure safety treatments, safety improvement for bicyclist exists, however, the adoption and implementation can be limited by the lack of consolidated geometric design guidance and standards." - need an updated @aashtospeaks Bike Guide Now!
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks Recommendation from @NTSB to @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm - put #protectedbikelanes in the next AASHTO Bike Design Guide. We need that published sooner rather than later!
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm "to date, no bicycle safety-- no bicycle safety specific countermeasure such as separated bike lanes and infrastructure and intersection safety treatments has been included in @USDOTFHWA programs." Specifically, the Proven Safety Countermeasures and Every Day Counts programs
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA Now shifting to bike and ride equipment, conspicuity (lighting and reflective materials) last reviewed in 1980. The @NTSB recommends that @USCPSC review conspicuity standards.

Could be interesting for city bikes, e-bikes, and "classes" of bikes. Not sure about blanket standards
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC The US does not allow newer lighting systems offered in other countries, @IIHS_autosafety has shown how vehicle lighting could be improved and @BikeLeague supported the auto industry's request for allowing newer lighting systems: regulations.gov/document?D=NHT…
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague "@NTSB has [already] made three recommendations to @NHTSAgov to incorporate collision avoidance systems into its New Car Assessment Program or NCAP which provides consumer information through a five star rating program." nhtsa.gov/press-releases…
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague "we believe that collision avoidance technologies could be modified to detect bicycles, there by reducing collisions and injuries. We also believe that @NHTSAgov's delays in updating NCAP have likely slowed the development and implementation of important the safety systems." 🙌
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague 38% of bicyclist fatalities are not related to head injuries and 68% of bicyclist emergency department visits are not related to head injuries - helmets are good, but not a cure all - and are not the way to reach #VisionZero
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague Why is the Netherlands so successful for bicycling? They've been working a long time to create better infrastructure - the US is "20 to 30 years behind" @BicycleDutch @Cycling_Embassy @fietsprofessor
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague @BicycleDutch @Cycling_Embassy @fietsprofessor Jennifer Homendy notes "US residents bicycled the least among the 14 countries." - how do we know? Unfortunately, we only get data about once a decade from nhts.ornl.gov
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague @BicycleDutch @Cycling_Embassy @fietsprofessor Jennifer Homendy of @ntsb board points to "@usdotfhwa crash [modification] factors, and that when they look at putting in separated bike lanes or some other bike lane, that it actually shows... more crashes, and more fatalities and injuries with more cyclists"- due to more biking
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague @BicycleDutch @Cycling_Embassy @fietsprofessor For @USDOTFHWA to make bicycle lanes a Proven Safety Countermeasure and Every Day Counts priority will take them actually engaging with bicycling safety as a rate question and caring about safety in numbers
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague @BicycleDutch @Cycling_Embassy @fietsprofessor Another great question from Ms. Homendy of @NTSB "why [do] we just focus on large vehicles? Because there are certainly blind spots in all sorts of vehicles." - Great to hear the answer that blind spot detection systems are becoming more standard, hope @NHTSAgov includes in NCAP
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague @BicycleDutch @Cycling_Embassy @fietsprofessor According to @NTSB the @EuroNCAP has gone much further than @NHTSAgov NCAP which has not had a significant update in a decade - if we tested AEB in NCAP we might not see it performs so poorly in @AAASafety @AAAnews tests theverge.com/2019/10/4/2089…
@NTSB @NHTSAgov @CDCgov @CDCChronic @CDCEnvironment @IIHS_autosafety @NACTO @aashtospeaks @AASHTOsean @JimTymon_AASHTO @TransComm @USDOTFHWA @USCPSC @BikeLeague @BicycleDutch @Cycling_Embassy @fietsprofessor Progress from @NTSB speed study to reduce use of 85th percentile as only method of setting speed limits: ntsb.gov/news/press-rel… - the @ncutcd has updated its guidance, now @USDOTFHWA needs to adopt the changes
