"cameras reduce collisions and injuries by an average of 5 percent and 2.5 percent per month on average, respectively collectively over the seven months following the introduction of a camera, collisions declined by 30 percent and injuries by 16 percent. That could explain why reported crashes dropped from 88,613 over the first 11 months of 2023 to 77,855 over the same period this year. And injuries are down from 49,747 to 45,421."
"the number of tickets drop dramatically as people start driving more slowly, revealing that "effective deterrence does not require harsh penalties," the report stated: "Violations spiked immediately following activation, then declined rapidly - a 26.5-percent drop from the first to second month and a 47.7-percent drop from baseline by the fifth month." As the graphic shows:"
National Academy of Sciences analysis shows automated speed cameras reduce collisions and injuries. Monthly reductions average about 5 percent for collisions and 2.5 percent for injuries. Collective declines over seven months after camera introduction reached roughly 30 percent for collisions and 16 percent for injuries. Reported crashes fell from 88,613 to 77,855 year-over-year for the same 11-month periods, and injuries decreased from 49,747 to 45,421. Ticketing spikes following activation then falls sharply as drivers slow, with a 26.5 percent drop month-to-month and a 47.7 percent drop from baseline by month five.
