License Plate Recognition System Automatically Captures Motor Vehicle Noise Disturbing Residents at

The license plate recognition system will further expand the scope setting, adjust the point arrangement, supervise the illegal disturbance of motor vehicle noise at night, and strive to create a quiet and livable working and living environment for the general public. Many car owners have received tickets for exceeding the standard of "noise". Shanghai has taken a serious step in dealing with traffic noise nuisance.
