How to Choose Traffic Guardrails: A Comprehensive Guide.
Traffic accidents happen all the time. One of the best ways to minimize the risk of injury in case of an accident is by using traffic guardrails. When choosing traffic guardrails, it is important to consider several factors. Here is a comprehensive guide on how to choose traffic guardrails.
1. What are traffic guardrails?
Traffic guardrails are physical barriers designed to guide the flow of traffic and protect drivers and pedestrians from accidents. They are typically made of steel and are installed along roadways to prevent vehicles from leaving the roadway or crashing into nearby obstacles.
2. Types of traffic guardrails.
There are several types of traffic guardrails that you can choose from depending on your needs. They include:
- W-beam guardrails: These are the most common type of traffic guardrails. They are made of a steel beam with a W-shaped cross-section, which gives them the flexibility to absorb the impact of a crash.
- Cable guardrails: These are made of steel cables that are strung between posts. They are designed to absorb the impact of a crash and are commonly used on highways.
- Concrete barriers: These are made of concrete and are used to separate traffic lanes or to prevent vehicles from leaving the roadway. They are commonly used on highways and bridges.
3. Design considerations.
When choosing traffic guardrails, it’s important to consider the design. Important considerations include:
- Length: The length of the guardrail should be long enough to provide adequate protection for the area it’s being installed.
- Height: The height of the guardrail should be sufficient to prevent vehicles from leaving the roadway.
- End terminals: The end of the guardrail should be finished with an end terminal to prevent the guardrail from piercing the vehicle in case of an accident.
4. Installation considerations.
Finally, it’s important to consider the installation process. Here are some important considerations:
- Soil conditions: The type of soil in the area will determine the type of installation method needed. Soft soil may require additional reinforcement.
- Slope of the roadway: The slope of the roadway will affect the stability of the guardrail. Special consideration should be given to installing guardrails on steep slopes.
- Costs: The cost of installation should also be considered. Different types of guardrails may require different installation methods and may have different costs associated with them.
In conclusion, traffic guardrails are an important safety feature on any roadway. When choosing traffic guardrails, it is important to consider the type, design, and installation requirements. By considering all these factors, you can choose the best guardrail to protect drivers and pedestrians on the road.
