Link travel speeds in road networks are fundamental data in many research areas of traffic, transportation, and logistics. To support the research in these areas, we develop a dataset, containing the travel speeds on each road link and in different time periods together with the real road network map. The dataset is collected from a representative megacity in Western China, Chengdu. The road network of this city involves different urban road network structures. The dataset shows the realistic variations and randomness of urban link travel speeds. This enables the research of real data-driven decision-making problems in traffic, transportation and logistics areas.
路网中的链路行驶速度是交通、运输和物流领域许多研究的基础数据。为了支持这些领域的研究，我们开发了一个数据集，其中包含每条道路链路以及不同时间段的行驶速度，以及真实的道路网络地图。该数据集是从中国西部的一个有代表性的特大城市成都收集的。该城市的道路网络涉及不同的城市道路网络结构。该数据集显示了城市链路行驶速度的现实变化和随机性。这使得交通、运输和物流领域的真实数据驱动决策问题的研究成为可能。
