An auxiliary facility for an emergency stop belt of an expressway tunnel

Abstract

The invention relates to the technical field of road traffic safety, in particular to an auxiliary facility of an emergency stopping belt of an expressway tunnel. The facility comprises an active guidance, a warning and protection device arranged around the emergency stop belt, a vertical mark is arranged on the end wall of the cross section B, and a plurality of reflective strips are arranged onthe tunnel wall on the left side of the emergency stop belt; Between that emergency stop belt and the road, a separation mark composed of a plurality of cat-eye spike is arranged, and a warning columnis arranged on the inspection auxiliary road in front of the cross section A; B cross section of that emergency stop belt is provided with an anti-collision steel guardrail, an elevation mark, a reflecting bar, a cat-eye spike, a warning column and an anti-collision steel guardrail to constitute active guidance, warning and protective facilities, and a reminder mark is arranged on the tunnel wallin front of the emergency stopping belt; The invention is reasonable in setting, and forms the reminding, warning and inducing action to the driver through the combination of the yellow and black elevation mark, the reflecting strip, the reflecting guide mark, the warning column and the reminding mark, so as to ensure the safe passage of the vehicle.

Description

technical field [0001] The invention relates to the technical field of road traffic safety, in particular to an auxiliary facility for emergency parking belts in expressway tunnels. Background technique [0002] In recent years, my country's transportation industry has developed rapidly, and the country's investment in transportation construction facilities in mountainous areas has continued to increase, and the number and mileage of tunnels have also gradually increased every year. Among them, the mileage of long tunnels and extra-long tunnels has increased by 10% per year. The regulations stipulate that emergency parking belts should only be set on the right side of the driving direction of long and extra-long tunnels, and the number of traffic accidents in long tunnels and extra-long tunnels and accidents in the emergency parking belt area is not uncommon. [0003] The tunnel emergency parking zone is an auxiliary infrastructure of the tunnel section of the highway project...

AI Technical Summary

Problems solved by technology

At the driver level, large-scale construction facilities such as emergency parking belts may have a certain impact on the safe driving of drivers in tunnels. The road cross-section in the emergency parking belt area changes drastically, especially from the perspective of visual environment information. The visual frame of reference has a certain influence, which will produce serious visual illusions, and at the same time, it will cause certain changes in the driver's psychology, which may cause visual deviation of the driving vehicle, resulting in traffic accidents such as vehicle rear-end collision and driving track deviation, or even Accidents such as hitting the tunnel inspection road or the side of the tunnel

[0004] The main traffic function of the emergency parking belt in the tunnel is to park faulty vehicles, evacuate road traffic in emergency situations and provide rescue sites for emergency vehicles and emergency personnel. There may be many vehicles parked. If a normal driving vehicle has an accident in the emergency parking area of ​​the tunnel, it may cause a major traffic accident with mass casualties

On the other hand, drivers in normal driving vehicles have inattention to vehicles entering or exiting the emergency parking zone, and are prone to rear-end collisions, scratches, etc., and even serious accidents such as rear-end collisions caused by emergency braking.
