SBIR Phase I: A Geographic Information System (GIS) Based Community Transit Information System (CTIS)

*** 9661397萨顿这项小企业创新研究第一阶段提案将由GIS/Trans， Ltd.执行，将研究和开发使用现有地理信息系统（GIS）技术的社区交通信息系统（CTIS）模块化设计的用户需求。该项目的创新之处在于提出了系统组件的模块化设计，并将这些组件与现成的GIS集成在一起。虽然现有的交通信息系统产品是为单一模式设计的，例如公共交通，但它们通常在路线或行程规划方面具有较差的图形和空间智能。目前没有一个是基于地理信息系统的，鉴于这项技术的使用和力量的出现，这是一个主要的弱点。该项目将研究全面CTIS所需的GIS空间智能，并分析迄今为止限制该领域产品开发的网络集成和多模式网络表示问题。该项目将通过对一系列社区交通服务（例如，共乘、穿梭巴士、叫车、辅助交通）进行信息系统分析，审查当前的用户需求。在确定系统组件之后，将对这些组件进行建模，以产生概念设计和功能规格说明。数据建模将采用已建立的软件工程方法和技术。预计该设计将包括如何将交通相关属性与多个网络表示联系起来的建议，并将这些属性显示在地图上，用于旅行信息或旅行规划目的。本研究将探讨设计一个能够处理实时数据并提供所需路线和调度信息的系统的可行性。此外，还将研究与全球卫星定位（GPS）和自动车辆定位（AVL）等技术的联系，以及在互联网上使用CTIS的可能性。拟议的社区T交通信息系统设计是对美国交通部支持的交通需求管理计划的及时响应，该计划旨在解决交通拥堵和环境污染问题。该技术将帮助规划者和用户以更有效和更环保的方式满足交通运输的流动性需求。拟议的产品将对所有公共交通供应商有用，包括运输机构、都市规划组织、地方政府、城镇。它将与领先的GIS供应商产品兼容，以便利用这些供应商提供的空间分析工具和网络分析程序。它还将与行业标准数据库技术兼容。GIS/Trans, Ltd.采用的方法的另一个特点是与该公司现有的GIS和运输产品的集成，因此用户将能够从一套程序中选择他们的特定要求。＊＊＊

*** 9661397 Sutton This Small Business Innovation Research Phase I proposal to be carried out by GIS/Trans, Ltd. will research and develop the user requirements for a modular design for a Community Transit Information System (CTIS) using off-the-shelf geographic information system (GIS) technology. The innovation in this project stems from the proposed modular design of the system components and the integration of these with off-the-shelf GIS. While existing transit information system products are designed for single modes, such as mass transit, they generally have poor graphics and spatial intelligence for routing or trip planning. None are presently GIS based, a major weakness given the emergence of use and power of this technology. The project will research the necessary GIS spatial intelligence for a comprehensive CTIS and analyze the network integration and multimodal network representation problems that have constrained product development to date in this field. The project will review current user needs by conducting an information systems analysis of a range of community transit services (e.g., rideshare, shuttle bus, dial-a-ride, paratransit). Following the identification of the system components, these will be modeled to produce a concept design and functional specification. The data modeling will employ established software engineering methodologies and techniques. It is anticipated that the design will include recommendations on how to tie the transit related attributes to multiple network representations and display these on maps for travel information or trip planning purposes. The research will investigate the feasibility of designing a system that can work with real-time data and provide the needed routing and scheduling information on-line. Linkage to technologies such as Global Positioning by Satellite (GPS) and Automated Vehicle Location (AVL), and the potential for access to the CTIS on the Internet will also be researched. The proposed design for a Community T ransit Information System is a timely response to the Transportation Demand Management program supported by the US Department of Transportation to combat traffic congestion and environmental pollution. The technology will assist planners and users to meet transportation mobility needs in a more efficient and environmentally conscious manner. The proposed product will be useful to all public transportation providers, including transit agencies, metropolitan planning organizations, local governments, cities and towns. It will be compatible with leading GIS vendor products in order to take advantage of the spatial analysis tools and network analysis programs that these provide. It will also be compatible with industry standard database technology. Another feature of the approach taken by GIS/Trans, Ltd. is the integration with the firm's existing GIS and transportation products, so that users will be able to select their specific requirements from a suite of programs. ***
