Traffic classifiers are small metal boxes (about the size of two house bricks) that collect traffic speed and volume data from two rubber tubes stretched across the road.
We use this data to assist with both short-term and long-term traffic engineering and road maintenance decisions.
Traffic classifiers are also known as traffic counters or road counters.
Traffic classifier responsibility
We are responsible for traffic classifiers placed on local roads within our municipality.
VicRoads is responsible for traffic classifiers placed on Freeways, Primary State Arterials and Secondary State Arterials (Green, Black and Red roads in the Melway street directory).
If you are unsure whether a road is managed by the City or VicRoads, please check our roads and responsible authorities page.
You cannot receive a speeding fine when travelling over a traffic classifier.
A traffic classifier is not a law enforcement device; it simply collects data for evaluation by engineers.
It does not take photographs or record car registration details.
However, please be aware that police are at liberty to place unmarked camera cars at any location at any time, including streets where we have placed traffic classifiers.
Traffic classifiers are placed for a variety of reasons. A traffic classifier in your street does not automatically mean that your street will have traffic calming devices installed, or that a speed hump will be installed where the traffic classifier has been placed.
Traffic calming devices will not be installed without resident and stakeholder consultation.
Traffic data collection period
Traffic classifiers are usually left in place for one to two weeks.
Traffic classifier damage
You can report damage to a traffic classifier for any local roads where we have them set up.
