Global trade depends on long-haul transportation, yet comfort for drivers on lengthy trips is sometimes neglected. Rough roads have a major negative influence on driver comfort and increase the risk of weariness, distracted driving, and accidents. Using Random Forest regression, a machine learning technique well-suited to examining big datasets and nonlinear relationships, this study examines the relationship between road roughness and driver comfort. Using the MIRANDA mobile application, data were gathered from 1,048,576 rows, including vehicle acceleration and values for the International Roughness Index (IRI). The Support Vector Regression (SVR) and XGBoost models were used for comparative analysis. Random Forest was preferred because of its ability to be deployed in real time and use less memory, even if XGBoost performed better in terms of training time and prediction accuracy. The findings showed a significant relationship between driver discomfort and road roughness, with rougher roads resulting in increased vertical acceleration and lower comfort levels (Road Roughness: SD-0.73; Driver's Comfort: Mean-10.01, SD-0.64). This study highlights how crucial it is to provide smooth surfaces and road maintenance in order to increase road safety, lessen driver weariness, and promote long-haul driver welfare. These results offer information to transportation authorities and policymakers to help them make data-driven decisions that enhance the efficiency of transportation and road conditions.
全球贸易依赖长途运输,但长途旅行中司机的舒适度有时会被忽视。崎岖的道路对司机的舒适度有重大负面影响,并增加疲劳、分心驾驶和事故的风险。本研究使用随机森林回归(一种非常适合检查大型数据集和非线性关系的机器学习技术)来研究道路粗糙度与司机舒适度之间的关系。通过MIRANDA移动应用程序,收集了1048576行数据,包括车辆加速度和国际粗糙度指数(IRI)值。使用支持向量回归(SVR)和XGBoost模型进行比较分析。尽管XGBoost在训练时间和预测准确性方面表现更好,但由于随机森林能够实时部署且占用内存较少,因此更受青睐。研究结果表明,司机不适与道路粗糙度之间存在显著关系,道路越崎岖,垂直加速度增加,舒适度越低(道路粗糙度:标准差-0.73;司机舒适度:均值-10.01,标准差-0.64)。本研究强调了提供平整路面和道路维护对于提高道路安全、减轻司机疲劳以及促进长途司机福利的至关重要性。这些结果为交通部门和政策制定者提供了信息,以帮助他们做出数据驱动的决策,提高运输效率和道路状况。
