It takes state-of-the-art technology and an expert team to monitor and manage the NSW road network 24 hours a day, seven days a week.
Traffic Commanders and Traffic Emergency Patrols
Traffic Commanders and Traffic Emergency Patrols (TEP) provide on-the-spot support for motorists by managing traffic around road incidents such as accidents and breakdowns.
We also have dedicated field resources to respond to and manage incidents in regional areas of NSW.
Our dedicated team of towing staff work to clear breakdowns and incidents in key locations such as Sydney Harbour Bridge, Sydney Harbour Tunnel and ANZAC Bridge.
Tidal Flow Systems
Traffic follows a predictable pattern at different times of the day on Sydney's key roads. Roads and Maritime Services' Tidal Flow Traffic Systems increase the number of available lanes during peak times to maximise traffic flow.
Tidal Flow Systems were first used on the Sydney Harbour Bridge in the late 1940s and fully automated systems were introduced in 1985. With more than 175,000 vehicles crossing the bridge every day, the Tidal Flow Traffic System is a critical part of its traffic management.
Traffic Monitoring Cameras
Roads and Maritime Services' Transport Management Centre (TMC) has a network of over 1,200 Closed-Circuit Television (CCTV) cameras monitoring traffic throughout Sydney and in key locations across NSW, linked via a computerised video control system.
Variable Message Signs and Variable Speed Limit Signs
Variable Message Signs (VMS) are placed at over 580 strategic locations across the NSW road network and Variable Speed Limit Signs (VSLS) are situated on major arterial roads including the M4 Motorway, M5 Motorway, F3 Freeway and General Holmes Drive.
Together with real-time communications tools, they help reduce delays, keep traffic flowing smoothly and improve driver safety, allowing Roads and Maritime Services to vary speed limits based on traffic volumes, unfavourable road or weather conditions and incidents.
VMS also inform motorists of delays, changes in traffic conditions and, when not required to manage traffic, provide information on Roads and Maritime Services' road safety awareness program.
Public Transport management
Liaison officers from the State Transit Authority, private bus operators, Railcorp and Sydney Ferries are based at the TMC to help manage public transport services.
Public Transport Information and Priority System (PTIPS) was developed by Roads and Maritime Services as part of the Bus Priority Strategy. It works with SCATS to manage traffic light timings and allow buses to run as close as possible to their timetables.
Currently all the STA buses are deployed with PTIPS and plans are under way to deploy PTIPS on other non Government buses.
TMC staff, working with event organisers other government agencies and local councils, effectively plan and implement safe traffic arrangements for major events, ensuring minimal impact to the public.
In recent years the TMC has helped manage a number of events, including the visit by Oprah Winfrey, World Youth Day and the visit of the Pope, Breakfast on the Bridge, the V8 Supercars at Sydney Olympic Park, and REPCO World Rally.
Annual events - including New Year’s Eve, the City to Surf and Mardi Gras Festival - continue to be successfully supported.
