NYC has an existing system, you can't run a red light at many intersections without getting a ticket. Overall compliance everywhere improves as culprits change habits or lose permits.

In NJ too many traffic violations are observed every day in addition to running stop signs and red lights. There is frequent crossing of solid lines, many without signalling. (Some vehicles, including trucks and Amazon delivery vans, take short cuts cutting through a Pulaski exit lane which has solid lines on both sides). Accidents on and near Pulaski show up on google maps all the time. Cameras could reduce accidents and big trucks on Pulaski would soon vanish.
