摘要:

道路平整度是基础设施的一个非常重要的道路条件,因为平整度影响乘客的安全性和乘坐舒适性。道路会随着时间的推移而恶化,这意味着必须持续监测道路平整度,以便准确了解道路基础设施的状况。在本文中,我们提出了一个机器学习管道,用于使用汽车的垂直加速度和车速预测道路粗糙度。我们比较了著名的监督机器学习模型,如线性回归,朴素贝叶斯,k-最近邻,随机森林,支持向量机,和多层感知器神经网络。该模型是在时间和统计域中计算的一组最佳选择的特征上训练的。结果表明,机器学习方法可以准确地预测道路粗糙度,使用安装在传统乘用车中的成本可接近的车载传感器的记录。我们的研究结果表明,该技术非常适合满足未来的路面状况监测,使广泛的道路网络的连续监测。

英文摘要:

Road roughness is a very important road condition for the infrastructure, as the roughness affects both the safety and ride comfort of passengers. The roads deteriorate over time which means the road roughness must be continuously monitored in order to have an accurate understand of the condition of the road infrastructure. In this paper, we propose a machine learning pipeline for road roughness prediction using the vertical acceleration of the car and the car speed. We compared well-known supervised machine learning models such as linear regression, naive Bayes, k-nearest neighbor, random forest, support vector machine, and the multi-layer perceptron neural network. The models are trained on an optimally selected set of features computed in the temporal and statistical domain. The results demonstrate that machine learning methods can accurately predict road roughness, using the recordings of the cost approachable in-vehicle sensors installed in conventional passenger cars. Our findings demonstrate that the technology is well suited to meet future pavement condition monitoring, by enabling continuous monitoring of a wide road network.
