Why Average Speed Cameras Beat Traditional Radar, Explained 2026

Average speed cameras are significantly more effective at reducing accidents than traditional point radar, according to a recent Australian meta-analysis. The study found that average speed cameras cut accidents by 30%, while traditional radar reduced them by 20%.

The research analyzed 15 studies on traditional radar and four on average speed cameras, revealing a key behavioral difference: the "kangaroo effect"—a term coined in the study—where drivers brake sharply before a radar and accelerate after passing it, creating dangerous speed fluctuations.

What the Study Found: Average Speed Cameras vs. Traditional Radar

The meta-analysis, conducted in Australia, compared the impact of both camera types on accident reduction. Traditional radar, which measures speed at a single point, was associated with a 20% decrease in accidents. Average speed cameras, which track a vehicle's speed over a stretch of road, achieved a 30% reduction.

More importantly, the study highlighted that average speed cameras were particularly effective at reducing fatal and serious injury accidents. This suggests that the technology's ability to enforce speed over a distance, rather than at a single point, leads to more consistent speed compliance and safer driving behavior.

Why the Kangaroo Effect Makes Traditional Radar Less Effective

The kangaroo effect describes a common driver behavior: upon spotting a radar camera, drivers abruptly brake to avoid a ticket, then accelerate once past it. This creates a "kangaroo" pattern of speeding up and slowing down, which can be hazardous.

Such sudden speed changes can lead to rear-end collisions and other accidents, especially in dense traffic. The study notes that this behavior undermines the safety benefits of traditional radar, as drivers only slow down temporarily near the camera.

Average speed cameras eliminate this problem by measuring speed over a longer distance. Drivers cannot simply brake for a moment; they must maintain a legal speed throughout the entire monitored zone.

How Average Speed Cameras Work

Average speed cameras use a network of cameras to record a vehicle's entry and exit times over a specific stretch of road. The system then calculates the average speed. If the average exceeds the limit, a ticket is issued.

This method ensures that drivers maintain a consistent speed, reducing the likelihood of sudden braking or acceleration. It also encourages smoother traffic flow and lowers the risk of accidents caused by speed differentials.

Key Takeaways from the Research

• Average speed cameras reduce accidents by 30%, compared to 20% for traditional radar.
• The "kangaroo effect" causes drivers to brake sharply before traditional radar and speed up after, creating dangerous speed fluctuations.
• Average speed cameras enforce speed over a distance, promoting consistent compliance and smoother traffic flow.
• The study analyzed 15 traditional radar studies and four average speed camera studies, with a focus on fatal and serious injury accidents.
• Average speed cameras are particularly effective at reducing severe accidents, making them a valuable tool for road safety.

What This Means for Drivers and Policymakers

For drivers, the message is clear: average speed cameras require sustained compliance with speed limits, not just a momentary slowdown. This can lead to safer driving habits and reduced accident risk.

For policymakers, the study provides evidence that investing in average speed cameras could yield greater safety benefits than traditional radar.
