What do traffic engineers aim to balance when managing traffic flow at intersections?

Traffic engineers aim to balance vehicle volume with safety when managing traffic flow at intersections because these are critical factors influencing the overall efficiency and safety of road systems. Achieving a high vehicle volume often leads to congestion if not properly managed, which can increase the likelihood of accidents. Ensuring that safety measures are in place, such as adequate sight distances, appropriate signal timing, and safe pedestrian crossings, helps protect all road users. The goal is not only to facilitate the smooth movement of vehicles but also to maintain a safe environment for pedestrians and cyclists, thereby minimizing the risk of collisions and promoting an effective transportation network. This balance is essential in designing intersections that accommodate the needs of all users while ensuring that traffic operates as smoothly as possible.
