摘要

私家车在全球变暖问题上扮演着重要的角色。据估计,汽车使用的汽油每加仑排放24磅二氧化碳和其他温室气体,约占总排放量的20%。在燃料的提取、制造和运输过程中,会产生超过5磅的吸热污染物,而需要注意的是,汽车的排气管每加仑会直接释放超过19磅的污染物。目前,汽油动力汽车的燃油效率通常在每加仑22.0英里左右,年行驶里程为11,500英里。因此,一加仑汽油的燃烧会导致大约8,887克二氧化碳被释放到大气中。1998年,汽车工业承诺到2008年将新车排放量减少25%。当时,新车的二氧化碳排放量约为每公里203克。目前,车辆的平均排放量约为170克/公里,预计到2020年以后,它们将不会减少到140克/公里。一辆标准乘用车每年排放的二氧化碳量通常在4.6公吨左右,但这可能会因燃料类型、燃油效率和里程等因素而波动。随着更多的变量发挥作用,预测排放量变得更具挑战性,一些实验设计考虑了可控变量及其相互作用。为了预测气体排放,我们开发了一个模型,利用汽车的属性来确定它是否超过了二氧化碳的阈值。如果确实如此,RTA将采取行动。预测二氧化碳排放的最佳技术之一是监督机器学习。

CO2 Emission Rating by Vehicles using Supervised Algorithms
Personal vehicles play a significant role in contributing to the issue of global warming. Gasoline used in cars emits an estimated 24 pounds of carbon dioxide and other greenhouse gases per gallon, which accounts for roughly 20% of all emissions. Over five pounds of heat-trapping pollutants are produced throughout the fuel's extraction, manufacture, and delivery, while it's important to note that cars release over 19 pounds per gallon directly from their tailpipes. At present, gas-powered vehicles typically achieve a fuel efficiency of around 22.0 miles per gallon, covering an annual distance of 11,500 miles. As a consequence, the combustion of one gallon of gasoline results in approximately 8,887 grams of CO2 being released into the atmosphere. In 1998, the automobile industry pledged to reduce new car emissions by 25% by 2008. At that time, CO2 emissions from new cars were approximately 203g/km. Currently, the average emissions of vehicles stand at approximately 170g/km and it is projected that they will not decrease to 140g/km until after 2020. The amount of CO2 emitted by a standard passenger car is typically around 4.6 metric tons per year, but this can fluctuate depending on factors such as fuel type, fuel efficiency, and mileage. While predicting emissions becomes more challenging as more variables come into play, some experimental designs consider controllable variables and their interactions. To predict gas emissions, we've developed a model that utilizes a car's attributes to determine if it exceeds the CO2 threshold. If it does, the RTA will take action. One of the best techniques for predicting CO2 emissions is supervised machine learning.
