Phoenix exploring controversial traffic system after U of A's study points to major downside
Phoenix, Arizona: The City of Phoenix is debating the return of red-light cameras, a topic that has sparked considerable discussion among city leaders and residents. The debate comes after a recent review by a city committee of a 75-page report from the University of Arizona, which examined the city’s previous red-light camera program that ended in 2019.
The University of Arizona study revealed that intersections equipped with red-light cameras saw a significant 28.7% decrease in crashes resulting in injuries or fatalities. This statistic highlights the potential safety benefits of reintroducing the cameras.
However, the study also pointed out a notable downside: an increase in rear-end collisions. Researchers attributed this rise to drivers abruptly stopping to avoid running red lights, leading to more frequent rear-end crashes.
Despite the mixed findings, the Phoenix Streets Department has stated that they are exploring potential options for automated traffic enforcement. This process will involve outreach to other cities that have implemented similar systems. No official decision has been made yet on whether the cameras will be reinstalled.
Public opinion on the issue remains divided. Some drivers believe that the cameras are an effective deterrent against running red lights, potentially saving lives.
"I think that they help people stop running red lights," one resident told ABC15. However, others argue that there are alternative methods to achieve traffic safety without the need for additional surveillance. "I feel like there are other ways to accomplish what they’re trying to do," another driver said in the same report.
The study recommends that before any cameras are reintroduced, the city should carefully consider the best locations for the devices and develop a comprehensive implementation plan.
Do red-light cameras really reduce accidents?
Yes they do reduce certain types like angle (T-bone) collisions. These are when a driver runs a red light and crashes into another vehicle traveling through the intersection. Studies, such as those reviewed by the Insurance Institute for Highway Safety (IIHS), have shown that intersections with red-light cameras generally see a reduction in this type of crash. The presence of red-light cameras also acted as a deterrent, encouraging drivers to stop at red lights rather than risk a ticket.
What are the issues with red-light cameras?
The main problem with red-light cameras is the increase in rear-end collisions. This happens when drivers, aware of the cameras, abruptly brake to avoid running a red light, causing the vehicle behind them to crash into their rear. Various studies, including those conducted in cities that have implemented red-light cameras, have reported an increase in rear-end collisions at camera-equipped intersections.
