Which group is primarily responsible for the development and implementation of traffic control procedures?

The group primarily responsible for the development and implementation of traffic control procedures is the traffic engineering department. This department consists of specialists who analyze traffic patterns, design roadways, and establish appropriate traffic control measures to ensure safe and efficient movement of vehicles and pedestrians. They use data and evidence-based approaches to create traffic management plans that address various scenarios, including traffic incidents.

While first responders, such as firefighters and emergency medical services, do play a crucial role in managing traffic at incident scenes, their focus is typically on safety and immediate response measures rather than the overarching regulations and procedures related to traffic control. Their efforts complement the traffic engineering department's work, but they do not replace the need for systematic traffic control development and implementation. Thus, the traffic engineering department is the key authority in establishing standardized traffic control procedures that guide the actions of first responders and maintain public safety.
