(URI) Collaborative Research: A Real-Time Urban Management System (for Dynamic City Visualization and Decision Support)

实时城市管理系统是一个正在设计的系统，旨在直接响应现代城市和直辖市在了解和管理实时信息和资源方面极其多样化的需求。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。原型系统的设计是为了使静态和实时(或时间)信息可用、可视化并立即在一组非常不同的用户群体、群体和功能之间共享。为了实现这一目标，我们打算将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培训和态势评估。这个应用程序代表了一个复杂的城市综合体，对于紧急情况和执法人员熟悉他们在紧急情况下不可避免地会发现自己所处的环境来说，通常是无法进入的。复制用于培训既困难又昂贵。交通警察表示非常有兴趣与我们合作，使用VR技术培训警察人员，以便在地铁站和隧道内进行应急响应。这项任务将在项目的前半部分进行，并将在下一步技术研究中描述技术重点。以上应用将为本研究提供方向和动力。我们还将把重点放在系统的结构上，以便在确定新的应用程序时，能够有效、简单地扩展和定制系统。其目标是减少对训练有素的专家构建这类应用程序的需求。如果没有这种能力，这种系统的扩散将确实是缓慢的。这里的目标是提供基本概念(数据模型、数据操作原语、外部数据库接口等)。3)在项目的后半部分，洛杉矶国际机场应急响应和培训系统的应用将成为项目2下开发的创作系统的试验台。我们认为，机场将是开发从航空照片自动更新模型的技术的理想地点。这是拟议研究的核心部分。而实际的紧急情况(撞车、恐怖袭击、地震等)如果不能按需生产，我们将能够拍摄航空照片，将图像与模型配准，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。机场在此期间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空照片和视频的“之前”模型，以再次探索进行变化分析所需的技术。机场还为实时提供车辆和人员位置等信息提供了许多机会，这些信息将被纳入系统。

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.
