Defense Line of Life on the Road - Road Safety Facilities

Road safety facilities refer to the multiple functions of pedestrian underpasses, safety protection, traffic guidance, isolation and closure, and glare prevention along the road to ensure the safety of driving and pedestrians and give full play to the role of the road. As an important part of the road, road safety facilities organically integrate people, environment, vehicles and traffic management departments, which set it along the road with scientific design for the whole process, so as to make the road come into play.


1. Types of road safety facilities


There are many types of road safety facilities. They are mainly guardrail belts, plastic road cones, anti-collision barrels, speed bumps, parking locks, protective nets, anti-glare nets, wide-angle mirrors, police woolen lines, crystal guards, traffic clothing, highway auxiliary facilities, and traffic signal lights, markings, guardrails, isolation fences, round signs, guide signs, road spike anti-glare facilities, traffic safety education bases, etc. Among them, traffic signs, traffic markings, guardrails, sight guidance settings, anti-glare facilities, isolation fences and other components also play an important role.


2. Principles of setting up road safety facilities


2.1 Principles of guardrail setting:

The general setting principle of ordinary wave guardrail is that the height of the foundation fill of the whole line is higher than 3cm and it should be set on both sides of the road. Located on both sides of the bridgehead and the passage, wave guardrails should be reinforced on the roadside of the section 8cm from the bridgehead. When setting the roadside guardrail, it should ensure that the shortest set length is 70m. Besides, the wave guardrail need to be set continuously if the distance between the two sections of roadside guardrail is less than 100m.


2.2 Principles of anti-glare facilities:

Anti-glare facilities could be divided into anti-glare panels, fan-shaped anti-glare slabs, and anti-glare nets. On the isolation belt in the middle of the road, the planted vegetation not only plays the role of beautifying the city and purifying the urban air, but also plays a role in preventing dazzle. That's why it becomes one of the types of anti-glare facilities. When suspecting anti-glare facilities, the best angle of the road should be 8 degrees. In most cases, green is used to match the surrounding green belt, and it is coordinated with the actual environment to ensure the beauty of the surrounding environment.


2.3 Principles of traffic marking setting:

First, we must ensure four edge lines. Secondly, toll island zebra crossings and directional arrows should be set up at toll gates and other places, and signs of decelerating zebra crossings should be set up. Finally, marking lines should be drawn in appropriate positions.


2.4 Principles of setting traffic signs:

Traffic signs should set up mainly based on the road traffic, so that drivers can obtain traffic information timely and effectively during the driving process. Besides, traffic signs can guide the vehicles correctly and ensure the safety of the highway, which also play an important role in the highway. At the same time, it is necessary to ensure that the setting of signs should not only play a corresponding role, meet the setting standards, but also be able to coordinate with the surrounding environment, so as to avoid the setting of traffic signs being too abrupt and affecting the beauty of the environment.
