9817773MuntzThe Real-time Urban Management System is a system, which is being designed to respond directly to the extremely diverse needs of modern cities and municipalities in their need to understand and manage real-time information and resources. The primary problem that this system will address is the need to facilitate collaboration and sharing of information amongst dissimilar (multi-disciplinary) user groups. The prototype system is being designed to allow information, both static and real-time (or temporal), to be made available, to be visualized and to be shared in an immediate fashion across a very diverse set of user populations, groups and functions. These will include civic departments as well as with society and the community as a whole.In order to accomplish this objective we intend to focus on threeDifferent application areas. They are:1) Police emergency response training and situationAssessment for the Los Angeles metro subway system. This application is representative of an intricate urban complex which is normally inaccessible for familiarizing emergency and law enforcement personnel with the environment which they will inevitably find themselves during an emergency situation. It is both difficult and expensive to replicate up for training. The transit police have expressed great interest in collaborating with us in the use of VR techniques in training police personnel for emergency response in the metro stations and tunnels.This task will be carried out in the first half of theProject period along with the technology focus described next.2) Technology research. The application above will provide the direction and impetus for the research. We will also focus is on the structuring of the system to permit efficient, simple extension and tailoring of the system to new applications as they are identified. The objective is to reduce the need for highly trained experts to buildSuch applications. Without this capability the proliferation of such systems willbe slow indeed. The goal here is to provide the basic concepts (data models, data manipulation primitives, interfaces to external databases, etc.) that permit relatively quick and efficient contruction of new applications.3) Application of the system to emergency response and training for the Los Angeles International Airport will, in the second half of the project, be the testbed for the authoring system developed under item 2.We feel that the airport will be an ideal site for developing the technology for automatic update of the model from aerial photographs. This is a central part of the proposed research. While actual emergencies (crashes, terrorist attacks, earthquakes, etc.) can not be produced on demand, we will be able to take aerial photographs, register the images with the model and develop the techniques to update the model with, for example, the current positions of planes, location of emergency vehicles, etc. The fact that the airport is also due for some expansion and rennovation during this period will allow the use of a "before" model with some aerial photographs and video to again explore the techniques required to do change analysis an automatic model update. The airport also provides numerous opportunities for real-time feeds on the position of vehicles and personel for example which will be incorporated into the system.

9817773muntz实时城市管理系统是一个系统，旨在直接响应现代城市和市政当局在了解和管理实时信息和资源方面的极其多样化的需求。该系统将解决的主要问题是需要促进不同（多学科）用户群体之间的协作和信息共享。正在设计原型系统，以便提供静态和实时（或暂时）的信息，使其可视化，并立即在各种各样的用户群体、群体和职能之间共享。这将包括民政部门以及社会和整个社区。为了实现这一目标，我们打算把重点放在三个不同的应用领域。它们是：1)洛杉矶地铁系统的警察应急响应培训和情况评估。这个应用代表了一个复杂的城市综合体，通常情况下，紧急情况和执法人员无法熟悉他们在紧急情况下不可避免会遇到的环境。复制训练既困难又昂贵。交通警察表示非常有兴趣与我们合作，利用虚拟现实技术培训警察人员，以便在地铁站和隧道作出紧急反应。这项任务将在项目的前半部分进行，并在后面介绍技术重点。2)技术研究。上述应用将为今后的研究提供方向和动力。我们还将重点放在系统的结构上，以便在确定新应用程序时对系统进行有效、简单的扩展和裁剪。目标是减少对训练有素的专家构建此类应用程序的需求。如果没有这种能力，这种系统的扩散将是缓慢的。这里的目标是提供基本概念（数据模型、数据操作原语、到外部数据库的接口等），这些概念允许相对快速和有效地构建新的应用程序。3)将该系统应用于洛杉矶国际机场的应急响应和培训，在项目的后半段，将作为项目2下开发的编写系统的试验台。我们认为，机场将是开发航空照片模型自动更新技术的理想场所。这是拟议研究的核心部分。虽然实际的紧急情况（坠机，恐怖袭击，地震等）不能按需生产，但我们将能够拍摄航拍照片，将图像注册到模型中，并开发技术来更新模型，例如，飞机的当前位置，紧急车辆的位置等。在此期间，机场也将进行一些扩建和翻新，这一事实将允许使用带有一些航拍照片和视频的“之前”模型，以再次探索进行变化分析和自动模型更新所需的技术。机场还提供了许多机会，例如车辆和人员位置的实时信息，这些信息将被纳入系统。
