Tuning devices TAZ

The voting devices developed by the municipal civil engineering office are used for surveys. The aim is to get a mood picture on a particular question. With each device you can ask exactly one question that offers up to four different answer options. Each push of a button is registered by the device and aggregated in 10-minute intervals. This data is transmitted wirelessly to a database every ten minutes. The raw data is first aggregated to fixed hourly intervals and then adjusted and analysed. Currently, the voting devices are mainly used for the survey of satisfaction with Piazza Pop-up. The dataset contains the locations and the aggregated end results of each survey, before and after the cleanup.

**Purpose**: Needs assessment, controlling, impact measurement, general planning basis

由市政土木工程办公室研发的投票设备，用于各类民意调研活动。其核心目标为针对特定议题获取公众态度画像。单台设备仅可设置一道议题，且最多提供四种不同的作答选项。设备会记录每一次投票按键操作，并以10分钟为周期进行数据聚合。该类数据每十分钟将通过无线链路传输至数据库。原始数据首先会被整合为固定小时粒度的聚合数据集，随后开展校准与分析工作。目前，该类投票设备主要用于针对快闪广场（Piazza Pop-up）的满意度调研。本数据集涵盖了各调研活动的场地信息，以及数据清洗前后的最终聚合调研结果。

**应用场景**：需求评估、管控监督、影响评估及通用规划依据
