Pedestrian Counting System - Past Hour (counts per minute)

Current issue 23/09/2020Please note: Sensors 67, 68 and 69 are showing duplicate records. We are currently working on a fix to resolve this.This dataset contains minute by minute directional pedestrian counts for the last hour from pedestrian sensor devices located across the city. The data is updated every 15 minutes and can be used to determine variations in pedestrian activity throughout the day.The sensor_id column can be used to merge the data with the Sensor Locations dataset which details the location, status and directional readings of sensors. Any changes to sensor locations are important to consider when analysing and interpreting historical pedestrian counting data.Note this dataset may not contain a reading for every sensor for every minute as sensor devices only create a record when one or more pedestrians have passed underneath the sensor. The Pedestrian Counting System helps us to understand how people use different city locations at different times of day to better inform decision-making and plan for the future. A representation of pedestrian volume which compares each location on any given day and time can be found in our Online Visualisation.Related datasets: Pedestrian Counting System – 2009 to Present (counts per hour).Pedestrian Counting System - Sensor Locations

请注意：编号67、68及69的传感器存在重复记录问题，目前我们正在推进该问题的修复工作。

本数据集收录了全市部署的行人传感器设备采集的近一小时逐分钟定向行人计数数据。该数据集每15分钟更新一次，可用于分析当日不同时段的行人活动变化规律。

可通过sensor_id（传感器ID）字段将本数据集与传感器位置数据集（Sensor Locations Dataset）进行关联合并，该数据集详细记录了各传感器的位置、运行状态及定向读数信息。在分析与解读历史行人计数数据时，需重点关注传感器位置发生变更的情况。

请注意：由于传感器仅在有一名及以上行人经过其探测区域时才会生成记录，因此本数据集并非每台传感器每分钟均有对应读数。

行人计数系统（Pedestrian Counting System）可帮助我们掌握不同时段市民对城市各区域的使用情况，从而为决策制定与未来规划提供科学依据。

各区域在任意指定日期与时段的行人流量对比可视化成果，可通过本机构的在线可视化（Online Visualisation）平台查看。
