When the remaining openings are allowed to turn around the opening of the central opening, the active barrier shall be provided.
2, the length of the activities of the fence must be able to close the central partition opening, the only way to play the purpose of separating the traffic, so the requirements of the activities of the fence set length must be able to effectively close the central partition opening.
3, the activities of the fence is part of the road traffic management facilities, it must be with the main road and other traffic engineering facilities to coordinate with each other, the only way to fully play the functions of traffic engineering facilities. Therefore, in order to ensure that the central separation of the fence of the line of sighting function of continuous, smooth, requiring the height of the activities of the fence should be with the central separation of the height of the barrier to maintain coordination.
4, the requirements of the activities of the fence set on the outline of the standard or reflective film is to make the night activities of the fence has a good visual recognition, while the central separation of the side of the outline of the object will not be interrupted and cause the driver's visual error. The provisions of the provisions of the reflector specifications 4cm × 18cm consistent with the column outline, in line with this specifications of the reflective material in the high-speed conditions under the conditions of the driver can be correctly identified; at the same time with the central separation of the wheel that standard, of

5, when the central separation of the opening section of the road with anti-glare requirements, should be set in the activities of the fence anti-glare facilities. Anti-glare facilities type selection, set the spacing, set the height, shading angle and other technical conditions should be consistent with the provisions of the provisions of the provisions of anti-glare facilities.
