VMBs play a vital role in enhancing road safety. By displaying messages such as "Slow Down," "Accident Ahead," or "Foggy Conditions," VMBs can alert drivers to potential hazards. They can also manage traffic speeds by displaying real-time speed limits based on weather conditions, congestion, or accidents, minimizing the risk of collisions. https://hpad.dataone.org/s/BtnEEuO6wv
