轨迹数据与城市交通研究
直接查看

近期研究重心从单一轨迹建模转向以轨迹为驱动的城市交通系统级智能控制与评估,方法上强调边缘智能、不确定性感知与多目标权衡(如通行效率与排放)。

强化学习被广泛用于自适应交通信号控制,且控制器设计明确依赖本地轨迹观测而非中心化预测
奖励函数设计正从延误/排队长度等传统指标转向动量式、多目标(如通行量-排放)权衡导向

町田站地区社区枢纽“Hatmachida”/日建设计

随着可步行城市环境的重要性在全球范围内持续受到关注,“Hatmachida”成为一项务实的城市策略:它在一条主干道的街角嵌入一座仅22.7平方米的微型建筑干预,以此激发公共活动。该项目通过在城市肌理中刻意置入一个体量微小却富有活力的存在,力求在周边区域引发连锁效应。这种依托长期使用而不断演进的建筑实践,挑战了传统城市更新范式,并为未来城市塑造提出了一种替代性模式。

竞争性卫星部署与地球静止轨道的经济地理

地球静止轨道(GEO)承载了全球大部分卫星通信收入。国际电信联盟(ITU)通过各国主管部门协调并登记频率指配及相应轨道位置,但未就经度位置设定市场价格或产权凭证。本文探讨商业运营商在此行政管理体制下如何在GEO中进行卫星定位。借助空间排序模型,我们发现商业卫星的部署数量与某一GEO经度下方可触达收入成正比,并按空间折现率依观测角予以折现。我们估计的部署弹性接近1,即某一经度上方的卫星数量随其可触达收入同比例增长。相比之下,政府卫星的部署则与某一GEO经度所覆盖的人口规模成正比。我们通过实证验证了该商业模型:基于2012年部署数据估计的参数能较好预测2021年的分布;且该模型拒绝将中国GDP全部视为国际商业卫星舰队的可触达市场。反事实分析表明,低地球轨道(LEO)系统的竞争可能使GEO使用重心向亚太地区倾斜,而更高的空间折现率则可能使GEO使用进一步集中于高GDP国家。

企业与工人双重迁移驱动的城市形成

本文将新经济地理学中的核心—边缘模型(Core-Periphery model)加以拓展,该模型原本仅考虑由地区间实际工资差异所驱动的工人单向迁移;拓展后新增了由地区间实际利润差异所驱动的企业迁移。在此双重迁移模型中,解的行为在定性上与单迁移模型相似:1)空间上均匀的人口分布变得不稳定,最终形成若干个城市,其中企业与工人共同集聚;2)随着运输成本下降,城市数量减少。这些结果为单迁移模型的应用提供了更一般的理论依据。

TerraNova:面向人类世的基础模型

人类世的一个核心挑战在于将物理地球系统与人类社会建模为一个耦合系统,然而目前尚无学习所得的表征能够覆盖二者在观测尺度上的全部广度。我们认为其根本障碍在于几何结构差异:物理地球以忽略政治边界的连续场形式被测量,而社会数据则按行政单元(如国家)上报。现有地球系统基础模型适配前一种几何结构;将其与后一种几何结构耦合时,不得不依赖有损的边界平均操作。本文提出 TerraNova——一种在原始几何结构下训练的基础模型,输入包含 1,024 类物理与社会记录:其中 512 类为格网化地球系统场,另 512 类为国家级指标。专用编码器分别表征位置、国家、时间和任务;跨模态 Transformer 将其融合为统一的时空状态;超网络则为每个查询生成专属解码器,其证据性输出头返回预测分布。该表征通过两项对比学习目标实现耦合:一是基于人口加权的国家与其境内地理坐标的对齐;二是与预训练的、承载图像语义的地理空间嵌入对齐。经该解码器读出后,该表征在性能上可媲美专用于地理空间任务的编码器,同时拓展了后者未涵盖的维度(时间、海洋及不确定性),并支持国家级别的建模能力。冻结主干网络可在消费级硬件上数分钟内完成从稀疏观测重建稠密场,并快速适配至未见变量。

面向少样本遥感场景分类的局部一致传递式信息最大化方法(LC-TIM)

遥感场景分类正日益依赖于在大规模地球观测数据上预训练的基础模型。此外,传递式推理(transductive inference)——即利用整个未标记查询集的整体统计结构——天然契合遥感处理流程,因为在该流程中,大尺寸遥感影像通常被切分为图像块并以批处理方式联合推理。本文提出 LC-TIM(Locally Consistent Transductive Information Maximization),该方法在当前最优的面向少样本 CLIP 的传递式信息最大化(TIM++)目标函数基础上,引入一个局部一致性正则项,强制每个查询样本与其在特征空间中的 $κ$ 个最近邻样本的预测结果保持一致。该正则项以单一乘性因子形式嵌入闭式 $q$-更新中,仅带来可忽略的计算开销。我们进一步提出一种多源扩展方案,融合多个遥感基础模型生成的亲和图(affinity graph),从而进一步提升分类精度。为评估所提方法,我们构建了首个面向传递式少样本遥感场景分类的全面、开源基准,涵盖十个多样化数据集、两种遥感视觉-语言模型以及多种少样本设定,对 LP++、TransCLIP、TIM++ 和 LC-TIM 进行系统评测。实验表明,传递式方法始终优于零样本基线;LC-TIM 达到当前最优分类精度,尤其在低样本量(low-shot)情形下增益最为显著——此时邻域线索最具判别性。代码已开源:https://github.com/elkhouryk/LC-TIM
