摘要

在未来几年,车辆联网和通信将是改善道路安全的最佳解决方案。雨水是造成车祸的主要原因之一,因为它大大减少了车辆与地面之间的摩擦和驾驶员的能见度。在本文中,我们将介绍一种适用于降雨估计的创新方法,该方法基于从基站到车载LTE接收器的车载无线电链路上测量的功率衰减。该算法可区分无雨、弱雨、中雨、暴雨4种降雨类型。性能结果表明,该方法具有84.4%的精度和较高的空间分辨率。

Poster: Real-time rainfall estimation based on LTE vehicular communications for road safety applications
In the upcoming years, vehicular networking and communications will be an optimal solution for road safety improvement. Rain is one of the major cause of car accidents, as it dramatically reduces both friction between the vehicle and the ground and driver's visibility. In this paper, we will introduce a new and innovative method suited for rainfall estimation, which is based on the power attenuation measured on the vehicular radio link from the base radio station to an on-board LTE receiver. The proposed algorithm discriminates between 4 classes of rainfall as follows: no rain, weak, moderate, heavy rain. The performance results show 84,4 % accuracy as well as high spatial resolution.
