What are the different types of traffic signals and their purposes?

Traffic signals can be categorized into three main types: stop signals, warning signals, and regulatory signals. Stop signals, like red lights, indicate when to stop. Warning signals, such as yellow lights, alert drivers to prepare to stop. Regulatory signals, like green lights, indicate when it's safe to proceed.

Can you explain how traffic signals differ in various countries?

Certainly! Traffic signals can vary significantly by country. For example, in some countries, a flashing yellow light means to proceed with caution, while in others, it may indicate a warning. Additionally, the colors and shapes of signals can differ, reflecting local traffic laws and regulations.

What are the advantages of using smart traffic signals?

Smart traffic signals use sensors and algorithms to optimize traffic flow, reduce congestion, and improve safety. They can adapt to real-time traffic conditions, which helps minimize wait times and enhances overall efficiency.

How do traffic signals impact pedestrian safety?

Traffic signals play a crucial role in pedestrian safety by providing designated crossing times and signals. They help manage the flow of both vehicles and pedestrians, reducing the risk of accidents at intersections.
