Data subset for road condition modelling - car sensor data

The subset contains selected car sensor data from the LiRA project. The in-vehicle sensor data (.hdf5) were collected with a AutoPi Telematics Unit (3rd generation) connected to the vehicle's controller area network (CAN) bus. This unit includes a single-board Raspberry Pi computer with added GPS and accelerometer modules. The car sensor data is stored in a structured format (.hdf5) in five levels; (i) at the top level is route name (i.e., ‘CPH1’, ‘CPH6’, ‘M3’ or ‘M13’), (ii) device/vehicle (in this case on GM for GreenMobility cars), (iii) trip number or task id, (iv) pass number, and (v) GPS and sensor signals. This item is part of the collection "Live Road Assessment Custom Dataset (LiRA-CD)", https://doi.org/10.11583/DTU.c.6659909

该子集包含LiRA项目的精选车载传感器数据。本次采集的车载传感器数据格式为.hdf5，采集设备为第三代AutoPi远程信息处理单元，该单元通过连接至车辆的控制器局域网（Controller Area Network，CAN）总线采集数据。该单元搭载单板树莓派（Raspberry Pi）计算机，并外接GPS（全球定位系统）与加速度计模块。该车载传感器数据以五级分层的结构化.hdf5格式存储：(i) 顶层为路线名称（如“CPH1”、“CPH6”、“M3”或“M13”）；(ii) 设备/车辆层级（本次数据集的车辆均为GreenMobility品牌，标识为GM）；(iii) 行程编号或任务ID；(iv) 通行次数；(v) GPS与传感器信号数据。本数据集隶属于“现场道路评估自定义数据集（Live Road Assessment Custom Dataset，LiRA-CD）”，其DOI标识为https://doi.org/10.11583/DTU.c.6659909。
