AbstractOne of the important issues in an urbanizing world is understanding how public transportation affects the growth and development of regions. Public infrastructure investments are costly and thus understanding their contribution to regional development is imperative to assess the benefits given the high costs. Since public transportation is not randomly distributed across space, it is challenging to disentangle the amenity value of neighborhoods from that of the transportation network itself. This research considers an unexpected closure of a major transit network due to a hurricane and examines how this closure affected businesses, neighborhoods and commuters by utilizing a detailed dataset. This proposal will highlight the economic forces driving the complex relationship between public transportation and neighborhood dynamics. Thus the research will inform policy makers in what ways infrastructure projects may be funded and how these decisions shape the development of neighborhoods.Finding credible evidence of the value that commuters place on proximity to public transport is of first-order importance in an urbanizing world. This proposal utilizes as an exogenous shock, the unexpected closure of a major transit line for an extended period in a large city due to a hurricane. This closure was expected to cause major disruption to hundreds of thousands of commuters and thousands of businesses in the affected neighborhoods. This project utilizes this large information shock to disentangle the spatial equilibrium of urban networks into their component parts. In order to do this, the project will construct a novel dataset of residential history, detailed housing characteristics and rental price history. The project will explore fundamental questions about the nature of cities and neighborhoods and how the individual choices of consumers when choosing housing endogenously change the urban landscape, including how much, and in what ways, policy makers should fund transportation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

城市化世界中重要问题的摘要是了解公共交通如何影响地区的增长和发展。公共基础设施的投资是昂贵的，因此必须了解它们对区域发展的贡献对于评估高成本的收益至关重要。由于公共交通不是随机分布在整个空间之间，因此将社区的便利价值与交通网络本身的设施相关。这项研究认为，由于飓风的意外关闭，由于飓风而出乎意料的关闭，并通过使用详细的数据集来研究这种关闭如何影响企业，社区和通勤者。该提议将强调推动公共交通与邻里动态之间复杂关系的经济力量。因此，该研究将向决策者提供有关基础设施项目的资金以及这些决策如何塑造社区发展的方式的信息。找到通勤者对公共交通邻近公共交通的价值的可靠证据在城市化世界中具有一级重要性。该提议用作外源性冲击，这是由于飓风而在大城市长期长时间的大型运输线的意外关闭。 预计这种关闭将对受影响社区的成千上万的通勤者和成千上万的企业造成重大破坏。该项目利用这种大型信息冲击将城市网络的空间平衡置于其组成部分。为此，该项目将构建一个新颖的住宅历史数据集，详细的住房特征和租金历史记录。该项目将探讨有关城市和社区性质的基本问题，以及在选择住房时，消费者的个人选择如何内在地改变城市格局，包括多少，以及哪种方式，政策制定者应为运输提供资金。这项奖项反映了NSF的法规使命，并认为通过基金会的知识优点和广泛的criter scritia criter criter critia criter criter critia criter critia criteria criteria criteria criteria criteria criteria criteria crietia crietia cromitia cromitia cromitia又有值得的支持。
