Traffic Engineering and Control

Traffic Engineering and Control is a branch of transportation engineering that applies scientific principles to achieve the safe, efficient, and orderly movement of vehicles and pedestrians on roadway networks. This field involves the planning, geometric design, and operational management of traffic systems, including the strategic implementation and timing of traffic signals, signs, and pavement markings. By analyzing traffic data and flow patterns, engineers work to manage congestion, minimize travel delays, and reduce the frequency and severity of collisions to enhance overall mobility and safety.
