What is the purpose of an upstream buffer space in an incident management area?

The purpose of an upstream buffer space in an incident management area is to effectively separate the Transition Area from the Incident Space. This separation is critical for the safety of both responders and road users during incident management operations.

An upstream buffer creates a physical space that allows vehicles to transition safely from flowing traffic to the incident area, reducing the risk of collision with responders and allowing them to perform their work without immediate threats from moving traffic. This space also provides time for drivers to react and make adjustments as they approach the incident scene.

In the context of traffic incident management, this buffer is an essential component of scene safety, enhancing the overall effectiveness of response efforts while minimizing potential hazards associated with incident response.
