Compact Roundabout Safety Evaluation - Victoria

The Challenge

A new compact roundabout design was installed as an innovative intersection treatment, but its real-world safety performance needed to be rigorously evaluated. Traditional intersection analysis methods could not capture the nuanced vehicle interactions, approach behaviours, and near-miss events specific to the compact roundabout geometry.

Our Solution

Real Time Traffic deployed NearMiss technology to comprehensively evaluate the compact roundabout's safety performance, capturing vehicle approach speeds, trajectories, turning movements, and near-miss events to assess whether the design achieved its intended safety outcomes.

Implementation Details:

• NearMiss camera deployment covering all roundabout approaches
• Vehicle approach speed and trajectory analysis
• Turning movement counts and path analysis
• Near-miss event detection at all conflict points
• Before-and-after safety performance comparison

Results

Long-term Impact

Provided road designers with objective safety performance data for the compact roundabout design, informing decisions about future intersection treatments across Victoria
