The basic answer is, it is a "highway" marked on a nautical chart, it provides mariners in highly congested area's a set of specific "lanes of traffic" and is usually managed by Vessel Traffic Service or VTS (It's function is very similar to air traffic controllers)
Rule 10 in the link provided below will give you more info.
A separation of powers
It is the overcrowding of shipsusually found in traffic separation schemes.

Freight Operator Recognition Scheme (FORS) is a plan for London's freights that is responsible for increasing operational efficiency, reducing pollution from vehicles, traffic congestion and cost of business.

A Voluntary Separation Scheme (VSS) is a program implemented by organizations, often in the public sector, that allows employees to voluntarily leave their positions, typically in exchange for financial incentives or severance packages. The scheme aims to reduce workforce size or restructure without resorting to mandatory layoffs. Employees who opt for VSS usually receive benefits such as a lump-sum payment, extended health coverage, or assistance with job placement. This approach helps organizations manage costs while providing employees with a choice in their departure.
Planes typically fly at a vertical separation of 1,000 feet when at cruising altitude, but this can vary based on air traffic control regulations and the type of airspace. Horizontally, the separation can range from 3 to 10 nautical miles, depending on the altitude and the specific air traffic management rules in effect. Additionally, during takeoff and landing, aircraft may be spaced closer together to manage traffic efficiently.
A blank line in traffic flow diagrams typically indicates a separation between different streams of traffic but does not specifically show traffic flowing in the opposite direction. Instead, it often represents a gap or a neutral zone between lanes or directions. To indicate opposing traffic flow, arrows or other symbols are usually employed.
They indicate special areas or features such as anchoring, traffic separation, fishnet area, cables or pipelines, military exercise areas, and jetties
