For example, it’s from here that around 200 variable message signs (VMS) are programmed with traffic information, and telephone
calls about incidents are received.
When an incident occurs, CMCS analyses the affected area and prompts operators to apply pre-defined incident response plans,
which include controlling VMS, variable speed limit signs and cameras (CCTV).
Every year more than 220,000 people call the TMC’s dedicated line to report traffic incidents, with around 20% of incident alerts
originating from public reports. When a call comes in, the Integrated Radio and Telephony System (IRTS) ensures that operational
staff can effectively respond to these calls. IRTS combines the operations of the telephone system with control of the Government
Radio Network. With a touch of a screen, operators can alert emergency crews of traffic incidents. Real-time traffic information is
communicated through the TMC’s 132 701 Traffic Information Line.
Sydney’s Transport Management Centre (TMC) was commissioned in August 1999 for the Sydney 2000 Olympic Games when it
was used as the command and control centre for all Olympic public transport and traffic management.
