What are the two purposes of traffic directions and control?

• A. Facilitate a safe traffic movement
• B. Facilitate an efficient traffic movement
• C. Both A and B
• D. None of the above

Answer: (C)

Two main goals guide traffic directions and control: safety and efficiency. Safety means reducing crashes and conflicts among vehicles, pedestrians, and cyclists by clear signals, predictable right-of-way, and consistent rules that keep everyone safe. Efficiency means moving people and goods smoothly, minimizing stops and delays, and coordinating flow through signals, lane use, and timing so trips are reasonable and congestion is kept under control. When designed well, traffic control achieves both: safety enhancements help prevent delays caused by crashes, and smoother flow reduces the chances of risky driving that arises from congestion. Focusing on only safety or only efficiency would miss how these aims complement each other, so both are addressed by traffic directions and control.
