Background
The highway is an indispensable transportation mode in China, the danger avoiding lane is an important facility of the highway, and the danger avoiding lane is a special lane which is additionally arranged on the outer side of a lane on a long and steep downhill road section and used for driving out of a vehicle with out-of-control speed (brake failure) to safely decelerate along a main line. At present, the danger avoiding lane in China is an uphill sand piling lane.
The sand-piled type vehicle danger avoiding lane mainly slows down the vehicle speed by increasing friction through sand piling, has the best speed reduction effect, and avoids tragedies of a plurality of car damages and deaths. However, when the vehicle is out of control to rush to the refuge lane, the front wheel of the cab of the vehicle contacts the sand pile first, and after the front wheel of the cab rolls a section of the sand pile, the rear wheel of the carriage is connected with the sand pile, so that the phenomena that the cab decelerates first and the carriage decelerates later are caused, and the carriage inevitably impacts the cab due to inertia during the period from the beginning of the deceleration of the cab to the beginning of the deceleration of the carriage, so that even if the vehicle is prevented from being damaged and casualties, the impact of the carriage on the cab due to the inertia causes the accelerated damage of parts at the joint of the cab and the carriage, and particularly when heavy goods such as profile steel and steel rings loaded on the plate type heavy truck are out of control to rush to the refuge lane, the profile steel and the steel rings in the carriage are likely to impact the cab to.
