Posted by Stephen Bauman on Tue Feb 2 22:35:35 2016, in response to Re: Summary and Video of November 2015 SBS meeting in Woodhaven, posted by BrooklynBus on Tue Feb 2 21:46:10 2016. From Impact Speed and a Pedestrian’s Risk of Severe Injury or Death, September 2011 by the AAA Foundation for Traffic Safety.Results show that the average risk of severe injury for a pedestrian struck by a vehicle reaches 10% at an impact speed of 16 mph, 25% at 23 mph, 50% at 31 mph, 75% at 39 mph, and 90% at 46 mph. The average risk of death for a pedestrian reaches 10% at an impact speed of 23 mph, 25% at 32 mph, 50% at 42 mph, 75% at 50 mph, and 90% at 58 mph. Risks vary significantly by age. For example, the average risk of severe injury or death for a 70‐year‐old pedestrian struck by a car travelling at 25 mph is similar to the risk for a 30‐year‐old pedestrian struck at 35 mph. These results could be used to inform efforts to improve pedestrian safety, for example, by limiting traffic speeds to levels that are unlikely to result in severe injury or death in places where pedestrians and vehicles may encounter one another, creating physical separation of pedestrians and vehicles in places where higher traffic speeds are desired, and developing vehicle‐based systems that detect pedestrians and warn the driver or brake automatically when a collision is imminent. |
