Executive Summary

Victoria police started to trial speed cameras in December 1989 and in April 1990 the current speed camera program in Victoria was launched. Operational data from the initiative were made available to monitor the changes in police operations as the initiative evolved. Speed camera operational data from July 1990, when first available in electronic form, to January 1992 have been used to monitor these changes.

The use of speed cameras was phased in overtime and appeared to level by mid-1991 in both metropolitan and rural areas of Victoria. Across Victoria from July 1990 to December 1991 there were:

  • 8,966 speed camera sessions at 1,698 sites
  • over 20,000 hours of speed camera operation
  • over 11 1/2 million vehicles checked of which an average of 11% were travelling over the set threshold speed.

The length of speed camera sessions gradually increased from around 2 hours to 3 hours in the period beginning from May 1991 onwards in all areas of Victoria.

The proportion of all vehicles checked that were over the threshold speed also dropped from May 1991 until October 1991, after which a lower proportion was maintained. This drop was most noticeable in the metropolitan area.

Although there was significant use of speed cameras on all days of the week their use on weekends was relatively lower. The level of use of speed cameras in 100 km/h speed zones was also relatively low. In the metropolitan area the level of speed camera use in 100 km/h zones was below 3% while the level in rural Victoria was below 12 1/2% at all times.

All police districts in Victoria used speed cameras to varying degrees. It was also found that the deployment of speed cameras across metropolitan police districts differed. Some districts spread their speed camera sessions over a large number of sites while others tended to return to the same sites more often.
