A movable isolation guardrail system and tidal lane changing method

Abstract

The invention discloses a movable isolation guardrail system and a tidal lane changing method, which relate to the technical field of intelligent transportation. The isolation barrier system includes a track for fixing the isolation barrier, a plurality of end-to-end isolation modules arranged on the track, a connection assembly for connecting adjacent isolation modules, and a control system. A movable isolation guardrail system and a tidal lane change method disclosed in the present invention move under the driving action of an electric push rod to avoid pre-buried tracks on the road surface and reduce damage to the road surface; at the same time, the track with iron sheets is laid on the road surface , the isolation module is equipped with an electromagnetic positioning device, and the isolation module is fixed by the attraction of the electromagnet and the iron sheet to improve the stability of the isolation guardrail; a connecting component is installed between two adjacent isolation modules, so that the isolation guardrail can realize the continuous movement of the curve , the lane change is more flexible, the moving trajectory is more in line with the vehicle trajectory, and the isolation guardrail can be controlled in sections.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a snake-like movable isolation guardrail system suitable for variable lanes and a tidal lane changing method. Background technique [0002] With the development of the economy, the problem of urban traffic congestion has become increasingly prominent, especially the problem of tidal congestion is one of the traffic problems that often occur in large cities. Related researchers have proposed the concept of tidal lanes, also known as variable lanes. [0003] The mobile barrier (pile) is one of the traffic equipment used in variable lanes, and is mainly used to separate the reverse traffic flow and ensure driving safety. Existing mobile isolation fences (pile) are generally made of metal, have a large weight, and move slowly. Moreover, intelligent isolation facilities need to embed a large number of tracks on the road surface, which will cause great da...

Problems solved by technology

In the transformation mode, the overall simultaneous translation method is adopted, the transformation form is rigid, and the movement of the guardrail does not match the vehicle trajectory, which seriously affects the vehicle traffic capacity and traffic safety during the movement
