The Newark intersection where two buses crashed early Friday, injuring 19 people and killing one of the drivers, was the first in the state to feature a surveillance camera designed to catch people running red lights.

The program began in 2009 and expanded to about two dozen towns and cities in New Jersey before it was discontinued in 2014 amid controversy and lawsuits.
