Reversible lane safety control method and system based on Internet of Things and storage medium

Abstract

The invention provides a reversible lane safety control method and system based on the Internet of Things and a storage medium, and the method comprises the steps: selecting a section of isolation belt needing tide control, enabling the isolation belt to be formed by the sequential arrangement of a plurality of isolation piers, and presetting the initial state of the isolation belt to be located on a first lane marking line; enabling the isolation belt to receive a tide control instruction sent by an external terminal, wherein the tide control instruction comprises a pre-adjusted second lane marking line; sequentially numbering a plurality of isolation piers of the isolation belt; sensing the speed V along the automobile and the distance S between the automobile and the first road barrierby the first road barrier through a sensor; calculating the braking distance L of the automobile according to the speed V of the automobile and the sliding friction factor u of the road; and if the braking distance L is greater than the distance S, delaying the movement from the first lane marking line to the second lane marking line, and waiting for the vehicle to pass. According to the invention, the intelligent control of the reversible lane is achieved, and the risk of traffic accidents is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an Internet of Things-based tidal lane safety control method, system and storage medium. Background technique [0002] Isolation piers are used to separate the traffic flow in the opposite direction or in the same direction, and have the function of prohibiting vehicles from turning left and pedestrians from crossing the road at will. They are generally set on the center line of the road or the lane dividing line. [0003] Due to the "tide phenomenon" of traffic, that is, the traffic flow in the direction of the city is large every morning, and the traffic flow in the reverse direction is small; at night, the traffic flow in the direction of the city is large, which aggravates the congestion. In view of this situation, the traffic organization is carried out in the way of variable lanes in the traffic diversion reconstruction, that is, when there are many vehic...

Problems solved by technology

The former requires a lot of labor costs, and the manual handling process is likely to lead to safety accidents, with a high risk; the latter replaces manual handling with tidal drive vehicles, although it saves manpower input, but due to the impact of the tidal drive vehicles on the shape of the isolation pier , The size has strict requirements, once the isolation pier does not meet the requirements, the tidal lane operation vehicle will not be able to operate normally, and the applicability is not high
