Roads Minister Duncan Gay has announced a budget allocation of $25.1 million for the Parramatta and Sydney police motorcycle response teams.
Each team will receive two extra officers, bringing the total number of officers at Parramatta to nine.
A Transport for NSW spokesman said the allocation would allow the Parramatta motorcycle response team to carry out regular patrols of Castle Hill and Blacktown, as well as in their core area around the Parramatta CBD. The team also already covers Westmead and Harris Park.
"Castle Hill and Blacktown have been added to regular patrols, as they are very busy centres," the spokesman said. "Police and traffic intelligence highlighted congestion and safety issues in those areas which could be effectively targeted by the [team]."
The Sydney team was established in August 2012 to target congestion and safety in Sydney's CBD. A team was established in Parramatta a year later.
Officers respond to traffic congestion and promote the free flow of traffic by targeting choked intersections, pedestrian offences and vehicles running red lights.
The team is linked to police at the Transport Management Centre and has access to real-time information.
"Since they were established the CBD and Parramatta, motorcycle response teams have carried out more than 26,000 patrol hours and have issued more than 28,000 [fines] for offences including mobile phone [use] and drink-driving," Mr Gay said.
