Description
Technical Field

Background
On a long downhill section of a road, a vehicle braking system is likely to fail, and for this purpose, a special danger avoiding lane is provided to protect an out-of-control vehicle from reducing the driving speed and safely stopping the vehicle, and reduce the damage to the vehicle, road property and road users. However, due to the influence of factors such as site conditions, it is difficult for the refuge lane to provide a sufficient braking length. In addition, information means are generally rarely considered in the initial stage of building the danger avoiding lane, and when an out-of-control vehicle enters the danger avoiding lane, the best rescue time is easily missed mostly by directly calling for help. When an out-of-control vehicle can not be safely parked and rushes out of the danger-avoiding lane, the vehicle with brake failure faces a dangerous situation of hanging in the air or dropping onto a cliff, and the flexible anti-falling net at the tail end of the danger-avoiding lane can play a role in saving the lives of drivers and reducing property loss.
At present, foreign relevant research is mainly focused on ski run protective nets and cliff rockfall protective nets, and domestic relevant research is mainly focused on side slope rockfall protective nets and net cable type energy absorption systems of danger avoiding lanes. The common end treatment method is a rigid anti-collision wall at the tail end, and a buffer device such as a sand bag, a waste tire and the like is additionally arranged in front of the anti-collision wall, but the buffer capacity of objects such as the sand bag, the waste tire and the like is small, and a vehicle out of control still has large kinetic energy to collide with the rigid wall, so that the vehicle is seriously damaged, and the life safety of a driver is seriously threatened. The flexible protective net has been researched for a certain time at home and abroad, and certain achievements are obtained. However, the study on the anti-falling net at the tail end of the danger avoiding lane is few, and the commonly used energy dissipation element is a pressure reduction ring, so that the pressure reduction ring can be damaged under the action of a larger force, and the maintenance is difficult.
