This approach is feasible to a certain extent, but there is an old saying that "blocking is worse than sparseness, and sparseness is worse than diversion". Instead of allowing two vehicles to collide completely, it is better to find a way to guide the incoming vehicle to deviate from the lane so as not to collide with the defensive vehicle or to reduce the collision. as a result of

Embodiment 1

[0025] In a highway accident, the surveyors used different methods to protect their own safety during the investigation of the accident.

[0026] Assume that the surveyors have adopted the device and layout scheme provided in the method of the present invention ( figure 1 ), then when an attacking vehicle reaches the uneven friction coefficient blanket after missing the warning of cones 1 and 2 due to the negligence of the driver, it starts to brake the vehicle completely, and the vehicle speed reaches 135km / h at the moment of braking. After passing through the uniform friction coefficient blanket, affected by the uneven friction of the blanket, the attacking vehicle deviates to the left side of its forward direction, and after colliding with the defensive vehicle parked obliquely, it deviates from the lane where the accident area is located. Figure 4 The simulation process diagram of the event is given, and it can be clearly seen from the diagram that neither the attack nor ...

Abstract

In view of the fact that most of the existing studies use the "blocking" method to protect accident investigators, this invention adopts the concept of "sparse" to design a blanket with uneven friction coefficient, combined with 2 cones, 1 alarm and 1 defense vehicle, through Reasonable layout and protection of accident scene investigators. The layout scheme is as follows: with the accident area as the origin, the direction of incoming vehicles as the horizontal axis, the first cone, the second cone, the uneven friction coefficient blanket, the alarm, and the defensive vehicles are arranged from far to near. The beneficial effect of the technical solution of the present invention is: before the attacking vehicle invades the accident area, it will go through the continuous warning, guidance and blocking of the two cone barrels, the uneven friction coefficient blanket and the defensive vehicle, and the attacking vehicle will be introduced into other lanes while making the defense The vehicle absorbs less energy from the attacking vehicle, so as to prevent the attack and prevent the vehicle from invading the accident area, thereby ensuring the safety of the investigators in the accident area; and the designed uneven friction coefficient blanket is light in weight, foldable and easy to carry.

Description

technical field [0001] The invention relates to the field of traffic safety, more particularly, to a method for protecting expressway accident investigators. Background technique [0002] Accident in-depth investigation is a necessary means to improve traffic safety, and accident scene investigation is an important basis for accident in-depth investigation. During the investigation of expressway traffic accidents, due to factors such as fast speed, good road conditions and driving fatigue, other vehicles are easy to invade the accident scene. Therefore, the safety protection of accident scene investigators needs urgent attention. According to the relevant provisions of my country's Road Traffic Safety Law, when a motor vehicle breaks down on an expressway, a warning sign should be placed 150 meters away from the direction of the vehicle. This reminds us that relevant devices can be properly installed within 150 meters to ensure the safety of personnel engaged in investigati...
