Background

The traffic flow mixing phenomenon is mainly represented by mixing of a right-turn vehicle with a non-motor vehicle and pedestrians, and is mostly reflected at an intersection of an urban road, and is specifically reflected as two types of conflicts: the first type of conflict is the conflict between the right-turning motor vehicle and the lateral pedestrians, and the second type of conflict is the conflict between the right-turning motor vehicle and the same-direction street pedestrians. The signal lamps are arranged in the urban road intersections for separating traffic flows, reducing conflict points and improving the safety of the intersections.

Accordingly, there is currently provided an isolation barrier at an intersection, which is classified into a fixed type and a buried type at a center line of a road or at a side of a road, wherein the fixed type isolation barrier includes concrete blocks mounted on the center line of the road or at the side of the road, and is constructed by connecting the blocks one by one and then fixing them on the center line of the road or at the side of the road with bolts.

The assembly comprises: a round tube upright post, on which a chassis is arranged; and the elastic rotating body is sleeved on the circular tube upright post, and the lower end surface of the elastic rotating body is abutted against the chassis. The assembly consists of the round pipe upright post and the elastic rotating body, when the automobile collides with the elastic rotating body, the collision force of the automobile is effectively absorbed by the elastic rotating body to be reduced, and the automobile is effectively prevented from running into a face opposite lane to collide or fly out of the lane, so that the automobile is kept to run in a correct lane. As further disclosed in chinese patent CN202022265993.9, the anti-collision column for road traffic safety comprises a rubber pier and a fixed ground pile, wherein the top of the fixed ground pile is fixedly connected with a spring, the center of the bottom of the rubber pier is provided with a mounting ring groove matched with the spring, and when the spring is in a natural telescopic state, a space is reserved between the bottom of the rubber pier and the top of the connecting plate. The anti-collision column can protect the safety of pedestrians and reduce the injury degree of the electric vehicle and the bicycle to the people and the vehicle after the electric vehicle and the bicycle collide with the anti-collision column.

However, the guard rail is made of rigid materials, is easy to incline or fall off after being impacted, and can influence normal use if not found or righted in time.
