A new freeway management system

Freeway management systems help make journeys safer and travel times more reliable.

They do this by controlling the flow of traffic both on and entering the freeway.  The systems also help traffic better cope with accidents and breakdowns.

We are installing a new freeway management system on CityLink and the Tullamarine Freeway. The system is a mix of:

  • lane use management signs 
  • stop / go lights on freeway entry ramps
  • CCTV cameras 
  • travel time information signs
  • electronic variable message signs 
  • automatic incident detection systems.

Coping better with incidents and congestion

The overhead lane use management signs (LUMS) help manage traffic incidents and congestion.

LUMS inform you of a change in speed limit and lane closures. They make it easier for emergency services to reach incidents and for you to pass safely. 

For serious incidents, they can help direct traffic off the freeway.   

Helping you make informed decisions

We are installing message signs on the freeway and on connecting roads. The signs will provide up-to-date travel times and advance warning of incidents. 

This information will enable you to make informed decisions about your journey.

Making merging easier

Ramp signals regulate the flow of traffic needing to merge onto the freeway. This makes merging easier and helps reduce congestion around the freeway entry ramps.

Electronic message signs let you know when the signals are operating. Generally, this is only when the traffic is heavy.

We will be installing ramp signals on:

  • all entries to CityLink and the Tullamarine Freeway
  • citybound entries on the Calder Freeway
  • on the Bolte Bridge ramp to the West Gate Freeway.

The signals on the Bolte Bridge ramp will allow us to control the flow of traffic off the Bridge. This is one of several measures for reducing congestion on the West Gate Freeway.
