Reusable Modeling Components for Simulating Land Use, Transportation, and Land Cover

***9818378 waddell这个城市研究计划（URI）项目开发了一种新的方法来评估两种特定的联系，这两种联系对于人类、建筑和自然环境之间相互作用领域中更复杂和综合的城市动态模型的发展至关重要。特别是，将调查土地利用与运输之间以及土地利用与土地覆盖之间的联系，重点是开发可重复使用的建模组件，以便在分析共同问题方面提供灵活性。将使用建模组件探讨的具体研究问题涉及空间、时间和行为的分辨率和规模如何影响分析结果。土地利用模式与城市地区的许多其他属性密切相互作用，包括交通模式、社会资本、空气和水质以及对自然生态系统的压力。这种相互作用是复杂的，例如，土地利用模式强烈影响交通模式，交通模式又影响空气质量和其他环境因素，而空气质量和其他环境因素又影响土地利用模式。同样地，土地利用、土地覆盖和环境压力源是高度相互依赖的，开发土地利用-土地覆盖模型为模拟城市-环境相互作用提供了基础。尽管存在这些复杂的相互作用，但在大多数城市模型中，土地利用被认为是一个外生变量，也就是说，土地利用模式只是简单地输入到模型中，而没有考虑反馈。在本研究中，建模组件将通过扩展UrbanSim土地利用模拟模型来开发，并使用面向对象的编程方法增加底层数据结构和行为的泛化。该项目的结果将是双重的。首先，将生成一组可重用的建模组件，用于开发人、建筑和自然环境之间动态交互的集成模型。软件和文档将通过互联网免费提供。其次，这些建模组件将应用于开发土地利用-交通综合模型和土地利用-土地覆盖模型。这项研究的一个关键方面将是培养与大都市规划组织的伙伴关系，这些组织将参与本项目中开发的模型的设计和测试。＊＊＊

***9818378 WaddellThis Urban Research Initiative (URI) project develops a new approach to assess two particular linkages that are central to the development of more sophisticated and integrated urban dynamic models in the domain of interactions between the human, built, and natural environments. In particular, the linkages between land use and transportation, and between land use and land cover will be investigated, with focus on the development of reusable modeling components that provide flexibility in analyzing common problems. The specific research questions that will be probed using the modeling components address how resolution and scale of space, time, and behavior affect the result of the analysis. Land use patterns interact strongly with many other properties of urban areas, including transportation patterns, social capital, air and water quality, and stresses on natural ecosystems. This interaction is complex, e.g., land use patterns strongly affect transportation patterns, which affect air quality and other environmental factors, which in turn affect land use patterns. Similarly, land use, land cover, and environmental stressors are strongly interdependent, and developing a land use-land cover model provides a foundation for modeling urban-environmental interactions. Despite these complex interactions, in most urban models land use is considered an exogenous variable, that is, the land use patterns are simply input into the model without accounting for feedback. In this research, modeling components will be developed by extending the UrbanSim land use simulation model, and adding generalization of the underlying data structures and behavior using object oriented programming methods. The results of the project will be twofold. First, a set of reusable modeling components will be produced for the development of integrated models of the dynamic interactions between the human, build, and natural environments. The software and documentation will be freely available via the Internet. Second, these modeling components will be applied to develop integrated land use-transportation models and also land use-land cover models. A key aspect of this research will be the cultivation of partnerships with metropolitan Planning Organizations that will participate in the design and testing of the models developed within this project. ***
