National Road Traffic Counts

A large data set of approximately 330Gb is size and 6.5 billion data points recording vehicle movements at almost 300 locations on the National Road Network. Due to the size and nature of this Dataset, data consumers will likely require some specialised tools and knowledge to handle and process it. Per Vehicle Records (PVR’s) record the presence of vehicles as they pass the traffic counter and can identify vehicle category, number of axels, date and time, vehicle length (in mm), the gap between vehicles, headway and lane number. Individual vehicles are not recognizable.

本数据集规模约330GB，共计65亿条数据记录，用于采集国家公路网近300个点位的车辆通行数据。鉴于本数据集的体量与特性，数据使用者通常需要配备专业工具并掌握相关专业知识，方可完成数据的处理与分析工作。单车记录（Per Vehicle Records，PVR）会记录车辆经过交通计数器时的通行状态，可识别车辆类别、轴数、日期时间、车辆长度（单位：毫米）、车辆间距、车头时距以及车道编号。该数据集无法对单台车辆进行个体识别。
