*** 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. ***

萨顿 由GIS/Trans，Ltd.进行的小型企业创新研究第一阶段提案将研究和开发使用现成地理信息系统（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拟议的系统组成部分的模块化设计以及这些组成部分与现有地理信息系统的整合。 虽然现有的交通信息系统产品是为单一模式设计的，如公共交通，但它们通常在路线或行程规划方面的图形和空间智能较差。 目前没有一个是以地理信息系统为基础的，鉴于这一技术的使用和力量的出现，这是一个主要的弱点。 该项目将研究一个全面的CTIS所需的GIS空间智能，并分析网络集成和多模式网络表示问题，这些问题限制了该领域迄今为止的产品开发。 该项目将通过对一系列社区过境服务进行信息系统分析来审查目前的用户需求（例如，共乘、穿梭巴士、电话叫车、辅助交通）。 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范。 数据建模将采用已建立的软件工程方法和技术。 预计该设计将包括关于如何将公交相关属性与多个网络表示联系起来并将其显示在地图上以提供出行信息或出行规划的建议。 本研究将探讨设计一个系统的可行性，可以与实时数据，并提供所需的路由和调度信息在线。 还将研究与全球卫星定位和自动车辆定位等技术的联系，以及在互联网上进入CTIS的可能性。 社区交通信息系统的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，以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运输机动性需求。 拟议的产品将对所有公共交通提供者有用，包括运输机构、大都市规划组织、地方政府、城镇。 它将与主要地理信息系统供应商的产品兼容，以便利用这些产品提供的空间分析工具和网络分析程序。 它还将与工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和运输产品相结合，以便用户能够从一套程序中选择他们的具体要求。 ***
