A data driven approach to the development and evaluation of acoustic electric vehicle alerting systems for vision impaired pedestrians (05-086)

Project Description: This project focused on evaluating candidate warning sounds for electric vehicles in a road and laboratory environment. Road and lab results were compared with the end goal of validating a lab environment which would facilitate future testing. Data Scope: The data consists of a multiple excel sheets that contain time series data from on-road testing. Data Specification: Listener-testing trials Only valid trials Trimmed to 100m and -10m (10m past the seated participants) distance Timeseries data, including: SPL (dB) Sound Data (Octave Bands) Vehicle Distance (m) Horizontal Speed (from DGPS, m/s) Button Status for each participant (pressed, not pressed)

项目说明：本项目聚焦于在道路与实验室环境中评估电动汽车的候选警示音，通过对比道路测试与实验室测试的结果，最终目标为验证可用于后续测试的实验室环境。
数据范围：本数据集包含多张Excel工作表，其内存储了道路实车测试得到的时序数据。
数据规格：仅收录有效的聆听测试试验；数据经裁剪至100米及-10米的距离范围（即就座受试者后方10米处）；所包含的时序数据涵盖以下内容：声压级（Sound Pressure Level，SPL，单位：dB）、倍频带（Octave Bands）声学数据、车辆间距（单位：m）、水平速度（源自差分全球定位系统（Differential Global Positioning System，DGPS），单位：m/s）、每位受试者的按钮状态（已按下、未按下）
