Bluetooth Radar Data for Road Traffic Monitoring

A reasonable approach to cope with increasing car traffic is the application of large-scale car traffic management solutions. Dense and widely applied car traffic monitoring is an important key prerequisite for this.Established solutions like e.g. induction loops, video-camera-based systems, or radar, do not suit all the needs with regard to installation effort, privacy, and cost efficiency.The use of off-the-shelf wireless chipsets for sensing purposes is a promising step towards cost reduction of traffic monitoring systems. It was already shown that the temporal analysis of the Received Signal Strength (RSS) within a wireless network nearby a street allows to monitor the traffic on the road quite accurately.This dataset contains RSS measurements that were recorded within a two-point Bluetooth network installed nearby a two-lane local road. The experimental setup, the used Bluetooth sensor devices, as well as the structure of the provided data files are described in detail in the provided README file.应对日益增长的机动车交通流量，合理的解决路径是部署大规模汽车交通管理方案。而高密度、广覆盖的机动车交通监测，正是这类方案落地的重要核心前提。当前主流的交通监测方案，如感应线圈、基于视频摄像头的监测系统或雷达等，在安装工作量、隐私保护与成本效益方面均无法满足全部需求。采用商用现成无线芯片组开展感知任务，是降低交通监测系统部署成本的极具前景的方向。已有研究证实，对道路附近无线网络中的接收信号强度（Received Signal Strength, RSS）进行时域分析，即可较为精准地实现道路交通监测。本数据集包含安装于双向两车道本地道路旁的两点式蓝牙网络所采集的RSS测量数据。本次实验的设置、所用蓝牙传感设备，以及提供的数据文件结构，均在附带的README文件中进行了详细说明。
