Researchers have developed a new type of guardrail made from a special alloy steel that not only provides excellent safety but also reduces the carbon footprint of transportation infrastructure. The new guardrail, which is 25% lighter than traditional ones, was tested in crash simulations and found to perform better than existing standards, with occupants at risk being significantly safer. The study also found that the new guardrail produces significantly less carbon emissions over its entire lifespan, making it a more sustainable option for transportation infrastructure. This breakthrough is in line with China's "Dual Carbon" goals to reduce carbon emissions while improving safety.
