VIDEO ANALYTICS TOWARDS VISION ZERO
CAMERAS & COMPUTERS TRACK NEAR MISSES, INFORM COUNTERMEASURES
-> Next City reports the traditional way to attack traffic safety is to identify places with a high number of crashes, then make changes at those places and wait a few years to see if the changes reduce crashes. Traffic engineers agree that you need a baseline of around three years of crashes to have statistically significant results. Now "computer vision and automated safety analysis" uses off-the-shelf cameras, or cameras that are already installed in an area, to film a given intersection. Computer algorithms track cars, bikes, people that move through the intersection and knows whether the moving blip is a person or a car, how fast they're going, how close they got to hitting another road user. This system has already helped Edmonton, Canada reduce collisions by 92 percent at one intersection. http://bit.ly/2jVcbw4
