论文摘要
人们流数据用于城市和商业计划和灾难管理等各个领域。但是，由于隐私问题，很难获得从移动电话收集的人流量数据，例如使用全局定位系统和呼叫详细记录数据。即使获得了数据，它们也很难处理。这项研究通过结合了有限城市地区的公共统计和旅行调查数据，开发了伪流数据，涵盖了日本的整个日本。该数据集不是实际旅行运动的代表，而是人们的典型工作日运动。因此，预计它将用于各种目的。此外，与旅行调查不同，数据集代表了整个日本的无缝运动，对覆盖范围没有任何限制。在本文中，我们提出了一种生成伪people-flow的方法，并描述了覆盖大约1.3亿人口的“伪级”数据集的开发。然后，我们使用来自多个大都市地区的手机和旅行调查数据评估了数据集的准确性。结果表明，确认了超过0.5的确定系数，以进行有关种群分布和跳闸量的比较。
People flow data are utilized in diverse fields such as urban and commercial planning and disaster management. However, people flow data collected from mobile phones, such as using global positioning system and call detail records data, are difficult to obtain because of privacy issues. Even if the data were obtained, they would be difficult to handle. This study developed pseudo-people-flow data covering all of Japan by combining public statistical and travel survey data from limited urban areas. This dataset is not a representation of actual travel movements but of typical weekday movements of people. Therefore it is expected to be useful for various purposes. Additionally, the dataset represents the seamless movement of people throughout Japan, with no restrictions on coverage, unlike the travel surveys. In this paper, we propose a method for generating pseudo-people-flow and describe the development of a "Pseudo-PFLOW" dataset covering the entire population of approximately 130 million people. We then evaluated the accuracy of the dataset using mobile phone and trip survey data from multiple metropolitan areas. The results showed that a coefficient of determination of more than 0.5 was confirmed for comparisons regarding population distribution and trip volume.
