What people are saying
The comments highlight the significance of impact speed on pedestrian injury risk, with references to specific statistics such as 'the risk of death goes up by 75% at 38mph' and 'the risk of severe injury is 10% at 16 mph,' illustrating thorough engagement with the research. The tone varies from concern to advocacy for change, reflecting both awareness and emotional impact, which aligns with high interest and impact scores.
Most posts acknowledge the research, with some emphasizing the importance of awareness about vehicle impact speeds and pedestrian safety.
The discussions show high interest, as they cite specific data, studies, and implications for urban safety and personal responsibility.
Posts demonstrate moderate engagement by referencing detailed statistics and expressing concern or outrage, indicating a deeper consideration of the topic.
The shared information and calls for awareness suggest that the discussions aim to influence perception and possibly behavior regarding speeding and pedestrian safety.
Abstract in brief
- The study found that as the impact speed of a vehicle increases, the risk of a pedestrian sustaining severe injuries or dying also increases, with specific thresholds identified for different levels of risk.
- At around 17 mph, the risk of severe injury (AIS 4 or greater) reaches 10%, and the risk of death reaches 10% at approximately 24 mph, with risks significantly rising at higher speeds.
- The risk of fatal injury varies with age, with older pedestrians (like 70 years old) facing similar death risks at lower impact speeds compared to younger pedestrians (like 30 years old), effectively making older pedestrians more vulnerable.]

Most liked on X and Bluesky@valentinejamoke @Goldieboii_ I don’t need to because the peer-reviewed research has been done. I know you don’t care, but for the hell of it, this is the research: Tefft BC. Impact speed and a pedestrian's risk of severe injury or death.

@menos1carro @pmmsanches @MUBipt Atropelado a 50 km/h só 1/8 (12%) de mortalidade é ir buscar os estudos mais otimistas. Muitos falam em 20 a 50%: https://t.co/edco9cBkB9 "The average risk of death reaches 25% at 32.5mph (50km/h) https://t.co/YiXTB9LU0c "50% mortalidade a 50km/h"
The reason I care about this is that hitting someone at 30 mph is likely survivable, but hitting someone at 50+ mph is very likely fatal. If you speed through streets like this, I really want you to know that I think you are evil.
@doomloopdisp Just 5mph could do the trick and no one would notice. This is just one of those reports I can’t unlearn https://t.co/qy4D3cU8va https://t.co/RaGW4yLV61

@endofamalek @porquenoguey @dylan___wilder @formerlyaustin X doesn't seem to like links, but he study is: Tefft BC. Impact speed and a pedestrian's risk of severe injury or death. Accid Anal Prev. 2013 Jan;50:871-8. doi: 10.1016/j.aap.2012.07.022. Epub 2012 Aug 27. PMID: 22935347. It's available on PubMed.
From a 2011 traffic study by B. C. Tefft “impact Speed and a Pedestrian’s Risk of Severe Injury or Death (Technical Report) Average Risk of Severe Injury for a pedestrian struck by a vehicle @ 16 mph is 10%, @ 23 mph is 25%, @ 31 mph is 50%, @ 39 mph is 75% and @ 46 mph is 90%

@pmacustodio @Mob_a_Serio Primeiro artigo que encontrei. Há muitos deste género. "The average risk of death reaches 10% at an impact speed of 24.1mph, 25% at 32.5mph, 50% at 40.6mph, 75% at 48.0mph, and 90% at 54.6mph." https://t.co/telI9peR6p
