摘要
监控路面状况是道路管理部门制定有效基础设施维护计划的一项重要任务。尽管智能手机已作为经济高效的实时解决方案被引入到这一领域,但在其实际应用之前必须解决几个难题。本研究探讨了如何利用基于智能手机的众包数据和人工神经网络(ANN)来提高路面状况评估的精度。首先,从安装在不同车辆上的四种不同智能手机模型中收集数据,包括垂直加速度、地理位置和速度。然后,垂直加速度数据的均方根与车速一起被用作 ANN 的输入特征,而真实的国际粗糙度指数(IRI)值则作为相应的输出特征。根据平均平方误差 (MSE) 和皮尔逊相关性等统计指标对 ANN 和回归模型进行的比较分析表明,ANN 优于回归模型。ANN 的平均平方误差(MSE)和皮尔逊相关性值(0.56 和 0.91)超过了回归模型(0.72 和 0.88)。此外,结果表明,与使用单一智能手机相比,利用众包智能手机数据能产生更好的结果。
An Artificial Neural Network approach to assess road roughness using smartphone-based crowdsourcing data
Monitoring road surface conditions is a crucial task for road authorities to develop effective infrastructure maintenance programs. Despite smartphones have been introduced as cost-effective and real-time solution for this purpose, several challenges must be addressed before their real-world application. This study investigates the utilization of smartphone-based crowdsourcing data and Artificial Neural Networks (ANN) to enhance the precision of road surface condition estimation. Initially, data are collected from four different smartphone models mounted in various vehicles, including vertical acceleration, geographic location, and speed. The root mean square of the vertical acceleration data, along with vehicle speed, is then employed as input features for the ANN, while the true International Roughness Index (IRI) values serve as the corresponding output features. Comparative analysis between ANN and regression models based on statistical metrics such as Mean Squared Error (MSE) and Pearson correlation revealed that ANN outperforms regression models. The obtained MSE and Pearson correlation values for ANN (0.56 and 0.91) surpass those of regression models (0.72 and 0.88). Moreover, results indicated that utilizing crowdsourcing smartphone data yielded superior outcomes compared to using a single smartphone for this purpose.
