Variable automated isolation guardrail system for reversible lane

Abstract

The invention belongs to the technical field of traffic equipment, and relates to a variable automated isolation guardrail system for a reversible lane. Guardrails are mounted on a left lane line and a right lane line of the reversible lane correspondingly, hydraulic systems composed of hydraulic cylinders, hydraulic oil pipes and electric hydraulic pumps are buried under the ground of the left lane line and the right lane line of the reversible lane, and reversible lane traffic light columns are mounted between the reversible lane starting point, the reversible lane ending point as well as between the adjacent reversible lanes; the electric hydraulic pumps are buried under the ground of the starting point of the reversible lane, and electrically connected with the reversible lane traffic light columns at the starting point of the reversible lane through underground cables and column control modules, and the hydraulic oil pipes transmit the hydraulic power supplied by the electric hydraulic pumps to hydraulic cylinders; and an annular coil vehicle detector is buried under the ground of the reversible lane. The variable automated isolation guardrail system for the reversible lane is simple in structure, low in cost and safe to use, can reduce the converting time of the guardrails, improves the traffic efficiency, improves the traffic jam situations of roads, achieves fully-automated intelligent control, and can implement dynamic adjustment according to real-time traffic flow.

Description

Technical field: [0001] The invention belongs to the technical field of traffic equipment, and relates to a variable automatic isolation guardrail system for tidal lanes. Background technique: [0002] In the city, the traffic flow between the working area in the city center and the residential area in the suburbs is the main source of traffic flow, and the resulting morning and evening peaks bring great pressure to urban road traffic. The direction of traffic flow in the morning and evening peaks has obvious time and directionality, that is, the traffic flow in the direction of the city is significantly higher than that in the direction of the city during the morning peak, and the traffic flow in the direction of the city is significantly higher than that in the direction of the city during the evening peak. This phenomenon is called A "tidal phenomenon" for traffic. There is a "variable lane", which can change the original out-of-city lane into a city-inbound lane during ...

Problems solved by technology

[0003] At present, there are three main ways to implement tidal lanes: one is traffic signal light control; the other is ground traffic sign control; the third is wheeled movable automatic isolation barriers. It is difficult to completely eliminate the dangerous state of the vehicle going against the road when the driver strays into the tidal lane from the normal lane by using the traffic signal lights without isolation guardrails and the ground traffic control method during the use process, and from a practical point of view, in the multi-lane two-way Under the driving traffic conditions, the technical solution without a central isolation barrier itself has a relativel
