Next City reports on something that   proves that everything old becomes new again with innovation, including the use of cameras monitoring intersections. UBC engineering professor Tarek Sayed states what everyone who has looked at the civic systems to get speed bumps or signalized crosswalks knows-“We have to wait for collisions to happen before we can do anything. A fundamental ethical and practical problem which faces traffic engineers is, in order to improve safety, you need a certain number of collisions … which you would try to prevent later,” says the University of British Columbia civil engineering professor. “It’s very reactive.”

Sayed has taken a proactive approach, developing a video camera system that monitors intersections for near collision misses, and has computers track the results. “The system, called, somewhat inelegantly, “computer vision and automated safety analysis,” uses off-the-shelf cameras, or cameras that are already installed in an area…
