Barriers

Barriers are physical structures designed to provide safety, control access, or demarcate boundaries in various environments. They are commonly used in a wide range of settings, including roads, construction sites, parking lots, airports, events, and public spaces.

In the context of traffic management, chapter 8 barriers are an essential component for the safety of motorists, pedestrians, and workers. They serve to separate opposing traffic, prevent unauthorized entry, guide the flow of vehicles, and protect individuals from potential hazards.

Barriers in traffic management come in various forms, such as concrete or metal guardrails, plastic or water-filled barriers, and temporary barricades. They are strategically placed along roadways, highways, and construction zones to ensure proper lane delineation, prevent crossover accidents, and protect roadside workers.

Beyond roadways, crowd control barriers are also used in crowd control and event management. They help direct crowds, maintain order, and create safe zones in crowded areas. Examples include crowd control barriers used at concerts, festivals, or marches, and security barriers at airports, government buildings, or stadiums.

In addition to safety and security benefits, barriers often offer visibility through reflective elements or bright colors, making them easily noticeable both day and night. Some barriers are designed to be movable or temporary to accommodate changing needs or facilitate easy installation and removal.
