A new prevention-first approach to intersection safety has gone live in Australia, and US transportation officials are taking note. Verra Mobility, a global provider of traffic enforcement and management technology, has launched its Red Light Delay system in select Australian cities. The system uses radar to detect vehicles that are unlikely to stop safely for a red light, then briefly delays conflicting traffic and, where configured, pedestrian signals — giving the violating vehicle extra time to clear the intersection before cross traffic moves.
While the rollout is currently limited to Australia, the technology is attracting attention from US road authorities who face a similar crisis: rising intersection fatalities. According to the National Highway Traffic Safety Administration (NHTSA), there were over 1,600 fatal crashes at traffic signals in the United States in 2023, with right-angle (T-bone) collisions accounting for nearly 40% of those deaths. Traditional red-light cameras have been controversial, often criticized as revenue generators rather than safety tools. Red Light Delay flips that model by intervening before a crash occurs, rather than simply issuing tickets afterward.
Red Light Delay integrates with existing traffic signal controllers. When the radar detects a vehicle approaching a red light at a speed that suggests it will not stop, the system sends a real-time message to the control cabinet, extending the all-red phase for crossing traffic by a few seconds. This brief delay prevents other vehicles from entering the intersection at the same moment as the violator. Optionally, the system can also pause a green pedestrian signal to keep walkers out of harm’s way.
The technology can be deployed as a standalone unit or added to existing red-light enforcement cameras. That flexibility is especially valuable for US cities with aging infrastructure: it allows a low-cost upgrade rather than a full replacement. Verra Mobility already operates camera systems in several US states, so integration is likely straightforward.
Right-angle collisions are among the deadliest crash types because the side of a vehicle offers little protection. In the US, an average of five people die each day in intersection-related crashes, and many more suffer life-altering injuries. The rise in distracted driving — combined with larger, heavier vehicles — has worsened the toll.
Red Light Delay directly addresses the moment of highest risk. It does not replace enforcement but adds a safety net. Steven Crutchfield, senior vice president and managing director international at Verra Mobility, described the philosophy behind the system: “Every Australian, wherever they are on the road, should be able to trust that the driver beside them at the red light will not become the reason they don’t make it home.” That same logic applies to the US.
For years, red-light cameras have been a polarizing tool. Opponents argue they are used mainly to generate revenue, while supporters point to reduced violations. Red Light Delay sidesteps the debate by offering a pre-emptive action. Rather than punishing the driver after the fact, it changes the traffic signal timing to avoid the collision altogether.
This prevention-first model is gaining traction among transportation engineers. The Institute of Transportation Engineers (ITE) recently issued a report calling for “dynamic intersection control” that adapts to real-time risk. Red Light Delay fits squarely into that vision.
Verra Mobility has not announced a US launch, but the company has a strong presence in American traffic management, with systems in Texas, California, Florida, and several other states. A pilot program in the US could be on the horizon, especially if Australian data shows a measurable reduction in right-angle crashes.
Local agencies are already testing similar concepts. For example, the City of Las Vegas has deployed radar-based sensors that can extend yellow times for speeding drivers. Red Light Delay goes further by directly manipulating the red phase for cross traffic.
Dr. Emily Tran, a traffic safety researcher at the University of Michigan, sees promise in the approach: “Most intersection fatalities occur in the first three seconds after a light change. A delay of even two seconds can be the difference between life and death. Radar detection is far more reliable than loop sensors for predicting violation intent.”
Verra Mobility’s Red Light Delay represents a fundamental shift in intersection safety — from collecting evidence after a violation to preventing the crash before it happens. As Australian road deaths continue to climb (up 1.7% in 2024, with no signs of improvement in 2025), the need for such innovation is clear. The US, which saw 1,314 traffic fatalities in 2024 (a similar rise to Australia’s), may benefit from adopting this or similar technology.
Whether Red Light Delay becomes standard in American intersections will depend on pilot results, public acceptance, and funding. But for the moment, it stands as a reminder that road safety doesn’t have to be reactive. As Crutchfield put it, “prevention-first systems like Red Light Delay should become a standard feature of intersection design.”
