Transport for NSW Deputy Secretary for Safety, Environment and Regulation, Tara McCarthy, said the new camera would operate in a school zone to target cars that ran red lights or sped.

She said between 2014 to 2018, six crashes occurred at this intersection and three people were injured, one seriously.

"We know that running red lights can lead to serious T-bone crashes or vehicles crashing into pedestrians," Ms McCarthy said.

Around 60 per cent of red-light speed camera offences are from people running red lights so we are addressing this problem head-on.

The new camera will operate in warning mode for a month.

Ms McCarthy said during this time drivers caught speeding or running red lights will be sent a warning letter to encourage them to change their behaviour.

Fines and demerit points will be sent to offending drivers at the end of this period.

Fines from red-light speed cameras go directly into the Community Road Safety Fund.
