北京文本交通数据集(BjTT)
收藏资源简介:
北京文本交通数据集(BjTT)是由北京人工智能研究院创建的一个大规模多模态数据集,旨在提高交通预测的准确性。该数据集包含超过32,000条时间序列交通记录,涵盖北京五环区域内超过1,200条道路的速度和拥堵水平。每条交通数据都附有一段文本描述,包括时间、地点和事件详情,如交通事故、道路施工等。数据集的创建过程涉及从地图服务和社交媒体平台收集数据,并通过去重和标准化处理。BjTT数据集的应用领域主要集中在交通预测,特别是在处理异常事件和提高长期预测准确性方面。
The Beijing Textual Traffic Dataset (BjTT) is a large-scale multimodal dataset developed by the Beijing Institute of Artificial Intelligence, designed to enhance the accuracy of traffic prediction. This dataset contains over 32,000 time-series traffic records, covering the speed and congestion levels of more than 1,200 roads within Beijing’s 5th Ring Road area. Each traffic record is accompanied by a textual description that encompasses time, location and event details such as traffic accidents and road construction. The development of the BjTT dataset involved collecting data from mapping services and social media platforms, followed by deduplication and standardization processing. The primary application scenarios of the BjTT dataset center on traffic prediction, particularly for addressing abnormal events and improving the accuracy of long-term traffic forecasting.
