Why are roundabouts being built at high-risk regional intersections?

In Victoria, over 40% of crashes resulting in people  being seriously injured or killed happen at intersections. When intersection crashes happen in regional areas, people’s injuries are often more severe due to greater travel speeds, the types of crashes and delays in getting medical assistance. To prevent these kinds of crashes from happening, we’re building roundabouts at high-risk intersections in regional Victoria.

How do roundabouts make intersections safer?

Roundabouts help to make intersections safer by reducing vehicle speeds at intersections and make it easier to choose a safe gap in traffic. In the event of a crash, roundabouts reduce the severity of the impact by changing the angles and speeds of a collision. Roundabouts are one of the safest types of intersections and reduce the risk of being severely injured by up to 90%.

Are roundabouts safer than traffic lights?

Yes, roundabouts are safer than traffic lights, mostly because they reduce the risk of high-speed crashes. The speed you travel at determines the likelihood of being seriously injured or killed in a crash, and the risk of being killed rises rapidly if you crash at speeds above 50 km/h.

How many new roundabouts are being built in regional Victoria as part of Towards Zero?

As part of Victoria’s Towards Zero plan, VicRoads are building 11 roundabouts in regional Victoria. These will be completed by the end of 2020.

How were the locations for new roundabouts chosen?

VicRoads and the Transport Accident Commission (TAC) assessed every high speed regional road and regional high speed intersection in Victoria to determine which were the most high risk. The intersections chosen for new roundabouts had the highest number of severe crashes over a five year period (2010 – 2015).

Will the new roundabouts have lighting?

Yes, all new roundabouts will include new lighting to highlight the roundabout and new approaching lanes. Wherever possible, we’ll use solar power to supplement conventional electricity sources.

Why are some roundabouts bigger than others?

The size of a roundabout depends on the volume and type of traffic that uses the roads adjoining to it. On busy roads, roundabouts may need two lanes to cope with the amount of traffic, and in regional areas a roundabout may need to accommodate larger vehicles like trucks, trailers and farm machinery.

Why are some roundabouts flatter than others?

In areas with restricted space, some roundabouts might be made flatter to allow large vehicles like trucks or farm machinery to drive over them.

This might be done if it’s difficult for large vehicles to use the roundabout normally.

How long does it take to build a roundabout?

From start to finish, the time taken to build a roundabout depends on its size, the volume of traffic, nearby utility services (like water, gas, phone and power) and, of course, the weather. Most roundabouts take about three months to build, but this can vary considerably.

How do roundabouts affect nearby landowners?

If extra land is needed to build a roundabout, nearby landowners could be affected. When this happens, VicRoads will negotiate with landowners about the amount of space needed to build the roundabout and negotiate a price to purchase the land. All efforts will be made to minimise any land acquisition for these new roundabouts.

Are roundabouts dangerous for trucks or motorcycle riders?

No, roundabouts aren’t dangerous for truck drivers or motorcycle riders when used at an appropriate speed.
