What they used before the traffic light of the first supercharge system for in?

Before the introduction of traffic lights, various methods were used to manage traffic at intersections, including police officers directing traffic and simple signals like flags or lanterns. Additionally, some cities experimented with mechanical devices or signs to indicate when vehicles should stop or go. These early systems were often inefficient and could lead to confusion, prompting the eventual development of standardized traffic lights to improve safety and traffic flow. The first electric traffic light was installed in 1914, leading to the modern systems we use today.
