Drivers can be distracted and impatient at New Jersey intersections. Horns blare, people get bored and check their phones and tempers rise. In the midst of such an environment, a sudden crash can be the last thing anyone needs. Collisions like this can start with confusion, boredom or frustration at the traffic light. While the signal sets the stage for an accident, driver choices trigger the impact.
How signals work at New Jersey intersections
Traffic signals use timing plans, sensors and software to sort who goes first, keeping traffic moving. Some intersections are controlled by lights with Adaptive Signal Control Technology (ASCT), a modern traffic control system that dynamically adjusts red, yellow and green light timing based on real-time traffic data.
Unlike traditional signals, which follow pre-set timing schedules, ASCT uses sensors to detect current traffic flow and optimizes signals every few minutes. This responsive timing improves travel time reliability and reduces congestion, which can also help cut accident risk. Further, by smoothing traffic flow, ASCT can decrease emissions and minimize stop-and-go driving, lowering crash potential at intersections.
Though powerful, ASCT is still underused, deployed at less than 1% of U.S. traffic signals.
Understanding the link between traffic signals and crashes
Regardless of the type of signal at any specific intersection, people still make risky moves. Impatient drivers may speed up or run red lights. Distracted drivers may not even notice a changing signal. When signals don’t adapt to changing traffic, backups form, increasing frustration, leading to unsafe behavior. In New Jersey, hundreds of thousands of crashes happen at intersections.
However, traffic lights are part of the story, not the whole story. In a crash investigation, you might look at whether signals used ASCT or not. You might also look at whether a driver ignored a red light or failed to yield. Distracted driving or running a stale yellow light may cause a serious collision that even a well-timed signal couldn’t prevent.
Better signals, safer roads
Upgrading traditional traffic lights to adaptive systems could help. ASCT can reduce delays, handle unexpected events and even cut some crash risks by up to 15% according to studies.
But no matter how smart the light, signals can’t control reckless driving or take away someone’s phone.
