A synthetic population is a simplified microscopic representation of an actual population. Statistically representative at the population level, it provides valuable inputs to simulation models (especially agent-based models) in research areas such as transportation, land use, economics, and epidemiology. This article describes the datasets from the Synthetic Sweden Mobility () model using the state-of-art methodology, including machine learning (ML), iterative proportional fitting (IPF), and probabilistic sampling. The model provides a synthetic replica of over 10 million Swedish individuals (i.e., agents), their household characteristics, and activity-travel plans. This paper briefly explains the methodology for the three datasets: Person, Households, and Activity-travel patterns. Each agent contains socio-demographic attributes, such as age, gender, civil status, residential zone, personal income, car ownership, employment, etc. Each agent also has a household and corresponding attributes such as household size, number of children ≤ 6 years old, etc. These characteristics are the basis for the agents' daily activity-travel schedule, including type of activity, start-end time, duration, sequence, the location of each activity, and the travel mode between activities.
合成人口是实际人口的一种简化微观表示。在人口层面具有统计代表性,它为交通、土地利用、经济和流行病学等研究领域的模拟模型(尤其是基于主体的模型)提供有价值的输入。本文使用包括机器学习(ML)、迭代比例拟合(IPF)和概率抽样在内的最新方法描述了来自合成瑞典出行()模型的数据集。该模型提供了超过1000万瑞典个体(即主体)、他们的家庭特征以及活动出行计划的合成复制品。本文简要解释了三个数据集(个人、家庭和活动出行模式)的方法。每个主体包含社会人口属性,如年龄、性别、婚姻状况、居住区域、个人收入、汽车拥有情况、就业情况等。每个主体还有一个家庭以及相应的属性,如家庭规模、6岁及以下儿童数量等。这些特征是主体日常活动出行日程的基础,包括活动类型、起止时间、持续时间、顺序、每项活动的地点以及活动之间的出行方式。
