Our newly developed intelligent height-restricted barriers are among the highway intelligent traffic equipment we have introduced in recent years. These barriers ensure the safety of bridge structures and vehicle operation, with a restricted height range from 3 to 4.5 meters. Depending on the specific on-site conditions, staff can adjust the height of the barriers at any time, taking just 1-3 minutes to transition from low to high. This facilitates the passage of oversized buses, passenger vehicles, and commuting vehicles, while拦下prohibitive large vehicles such as trucks. The barriers can also be raised to allow vehicles over 2.8 meters tall to pass through. To facilitate the分流 of vehicles over 2.8 meters, relevant departments have set up signage and directional signs in front of the barriers.
