What are the systems to promote the safe flow of vessel traffic in certain areas known as?

Traffic separation schemes are specifically designed systems that help manage the safe and efficient movement of vessels in busy waterways, especially in areas with heavy traffic. These schemes establish designated routes for vessels to follow, reducing the risk of collisions and enhancing navigational safety. They are particularly important in areas where the density of vessel traffic is high, allowing for a structured flow of maritime activity.

While shipping lanes and vessel traffic service zones also contribute to the organization of maritime traffic, traffic separation schemes are formalized through international regulations and are recognized and implemented globally, aimed directly at promoting safety in navigation. Navigational aids, on the other hand, assist vessels in determining their position and course but do not create the systematic separation of traffic streams that traffic separation schemes do.
