摘　　要：兰州市作为典型的河谷型城市,其独特的地理环境和复杂的交通布局为交通管理带来了极大的挑战。为了应对这一挑战,本研究构建了一个针对复杂场景下河谷型城市交通路口的视频流数据集。本数据集涵盖了兰州市内多个关键交通路口的视频监控数据,包括不同时间段(如早高峰、平峰时段)、不同天气条件(如晴天、雾天等)、不同交通状况(如拥堵、畅通等)、不同光照条件(如光线昏暗、光线充足等)下的视频流数据。数据采集时间为2021年11月16日、12月3日和12月9日。在数据处理方面,本文对视频数据进行了精细化的标注和分类,包括车辆类型、车辆所在车道等方面。本研究构建的兰州市交通路口视频数据集在严格的质量控制流程中,经过了完整性验证、清晰度评估、稳定性检查以及标注准确性校验,确保了数据的高度可靠性。本数据集丰富多样,旨在为智能交通系统的研发、交通拥堵治理和交通事故预防提供坚实的数据支持,从而为河谷型城市的交通流量分析提供实证基础。Lanzhou,a typical valley city,faces great challenges in traffic management due to its unique geographical environment and complex traffic layout.To address this challenge,this study has constructed a dataset of video stream at traffic intersections in valley-city Lanzhou under complex scenes.The dataset covers video surveillance data from several key traffic intersections in Lanzhou City,covering different time periods(such as morning peak and off-peak hours),weather conditions(such as sunny,foggy,etc.),traffic conditions(such as congestion,smooth flow,etc.),and lighting conditions(such as dim light,full light,etc.).The data was collected on November 16,2021,December 3,2021,and December 9,2021.In terms of data processing,this study has meticulously labeled and classified the video data,such as vehicle type,vehicle lane and so on.The dataset in this study has undergone rigorous quality control procedures,including integrity verification,clarity evaluation,stability check,and annotation accuracy verification,ensuring the high reliability of the dataset.This dataset is rich and diverse,aiming to provide solid data support for the development of intelligent transportation systems,traffic congestion control,and traffic accident prevention,and thereby providing an empirical basis for traffic flow analysis in river valley cities.
