Passive traffic regulation refers to the use of physical infrastructure and environmental features to control the flow of vehicles and pedestrians without active intervention. This approach relies on the design of the road system, signs, and landscape features to guide behavior and maintain safety.

Key elements of passive traffic management include:

  • Road geometry design
  • Traffic signs and markings
  • Barriers and other physical obstructions

For instance, roundabouts and speed bumps are examples of passive traffic tools that reduce speed and prevent accidents. These features create natural flow adjustments without the need for active enforcement.

"Effective passive traffic management improves safety, reduces congestion, and encourages more predictable driver behavior."

Common passive traffic elements and their functions:

Element Function
Roundabout Reduces speed and minimizes accident severity
Speed bumps Encourages drivers to slow down in residential areas
Pedestrian barriers Directs pedestrian movement safely across roads
