Automated enforcement systems have reduced highway-rail crossing violations by 78 to 92 percent along two corridors in Los Angeles, California.
Date Posted

In Los Angeles, CA, photo enforcement equipment has been installed along the Blue Line light rail system. The systems use high-resolution cameras to photograph motorists running under or around railroad crossing gates. It is triggered when vehicles cross over inductive loop detectors after the crossing gates have started down. Two photos of the vehicle, its license plate, and the driver's face are taken. On each photo is the date, time, speed of the vehicle, and number of elapsed seconds since the red flashing lights were activated at the crossing.


  • A 92 percent reduction in violations was found in a seven month project at Compton Boulevard.
  • A three month project at Alondra Boulevard resulted in a grade crossing violations reduction of 78 percent.
