标题： Urban Planning in 3D with a Two-tier LUTI model

摘要： 两层Lowry模型将人口和就业的动态模拟直接带入规划过程。 通过将区域建模与邻里设计相结合，该框架使规划者能够探索不同规划情景随时间的变化。 上层捕捉人员、工作和服务的区域流动，而下层则将这些流动分配到细粒度区域，如邻里或地块。 在CityEngine中实现，该方法允许对多尺度情景进行交互式可视化和评估。 南约克郡（英国）的一个案例研究说明了如何将区域预测转化为本地设计响应，将定量建模与三维空间规划联系起来。 显示英文摘要

摘要： The two-tier Lowry model brings dynamic simulations of population and employment directly into the planning process. By linking regional modelling with neighbourhood design, the framework enables planners to explore how alternative planning scenarios may evolve over time. The upper tier captures regional flows of people, jobs, and services, while the lower tier allocates these to fine-grain zones such as neighbourhoods or parcels. Implemented in CityEngine, the approach allows interactive visualisation and evaluation of multi-scale scenarios. A case study in South Yorkshire (UK) illustrates how regional forecasts can be translated into local design responses, connecting quantitative modelling with 3D spatial planning.
