Four common traffic safety facilities in traffic highways

1 Guardrails and railings

There are many types of traffic safety facilities, such as rigid guardrail, flexible guardrail, semi-rigid guardrail, etc. One of the more common guardrails is a rigid guardrail, which is mainly composed of cement, steel, etc., so this guardrail is not easy to deform; while the flexible guardrail has a strong toughness structure, so the guardrail has a strong buffer function. For the installation of guardrails, it is necessary to ensure that the guardrail has safety performance, but also to match the guardrail with the markings and signs, so as to effectively avoid the probability of traffic accidents.

2 Isolation facilities

In the construction of all traffic safety facilities, because the design of isolation facilities is relatively simple, it has attracted widespread attention. The forms of isolation facilities are more diverse, such as isolation walls and isolation nets are common isolation facilities. In the process of designing isolation facilities, not only its safety performance should be considered, but also the overall effect of the road should be considered. Otherwise, the unreasonable overall setting will easily cause visual fatigue of drivers and increase the probability of safety accidents.

3 Highway markings

One of the most common traffic safety facilities in traffic highways is highway markings, where the main manifestations of markings are numbers, symbols, arrows, etc. Under normal circumstances, marking lines are drawn by a variety of paints, and the main purpose of marking lines on expressways is to guide vehicles to drive normally. The markings set in the expressway are divided into four types: diversion markings, lane edge lines, entrance and exit markings and lane demarcation markings. Different markings have different functions. The purpose of setting the lane edge line is to remind the driver to drive according to the traffic lane; the purpose of setting the entrance and exit marking is to guide the vehicle safely, to encourage the vehicle to safely drive out, and to prevent collision with the protruding part; and to set the diversion marking and The lane dividing line can play a role in guiding the vehicle to a certain extent.

4 Anti-glare facilities

This kind of traffic safety facilities has many organizational parts, mainly composed of anti-glare nets, anti-glare plants, and anti-glare partitions. The anti-glare device can play a certain shading effect, and can help the driver to block the lights in front of the vehicle during driving. In addition, anti-glare facilities can also effectively prevent the driver from being affected by other vehicles during driving, resulting in dazzling phenomena.
