New safer speed technology in Tyabb

We’ve improved safety at the intersections of Dandenong-Hastings Road and Oneills Road in Tyabb, as we work towards a future where no one is seriously injured or killed on our roads.

What we’ve done

We’ve installed side road activated speed technology at the intersection of Dandenong-Hastings Road and Oneills Road in Tyabb to reduce the risk of crashes, without permanently lowering speeds. 

See how the technology works by watching the video below.

In the five years from January 2015 to December 2019, 73.5% of fatal intersection crashes in regional Victoria happened on high-speed roads with speeds between 80km/h and 110km/h.

Intersections in regional areas have a greater risk due to higher travel speeds, particularly where small side roads meet main roads.

Side road activated speeds will increase safety at some of Victoria’s highest risk intersections by:

  • instructing drivers on the main road to slow down if there are other vehicles approaching from side roads or waiting to turn right from the main road at the intersection
  • giving drivers on the main road more time to react if side traffic fails to give way
  • giving drivers on side roads more time to assess gaps in traffic and enter the main road safely
  • letting drivers know they’re approaching an intersection, which will prepare them for any merging traffic
  • significantly reducing the severity of crashes due to the reduced speed limit when traffic is merging from side roads.

A similar program in New Zealand has reduced serious and fatal crashes at intersections by 89% since 2012.

Infrastructure plays a vital role in preventing serious crashes. It also helps reduce the severity of crashes when they’re unavoidable.

Mistakes happen, which as humans we can’t always avoid. What we can do is build more forgiving road infrastructure so that when a mistake does happen on the road, it doesn’t cost a life.

The intersection of Dandenong-Hastings Road and Oneills Road in Tyabb has been identified as a high-risk intersection.

Between 2015 and 2019, crashes at this intersection resulted in one fatality and four serious injuries.

The Victorian Government, in partnership with TAC, is investing $1.4 billion into road safety infrastructure under Towards Zero, a plan for a future where no one is seriously injured or killed on our roads.
