项目摘要

Recent advances of communication technology, geographic information systems (GIS) and intelligent information systems have been making a great impact on the socio-technical systems. In particular, the new technology of high-accuracy global positioning systems (GPS) has made it possible to get centimeter-class positioning data of mobile objects in realtime at a reasonable cost.This work presents the general architecture of geographic information systems (GIS) for assisting the users in creating barrier-free street maps by using the Internet and the highly accurate global positioning systems (GPS). The purpose of the system is to provide an effective tool for supporting the creation and the use of network-based barrier-free street maps for physically-handicapped people in wheelchairs. The wheelchairs are equipped with the GPS antenna and the tablet PC for computing the current positions with a cm-class accuracy to navigate the people in the streets. The server collects the positions from the wheelchairs moving around the local service area. The collection of the data is stored and shared in the server after transformed into useful barrier-free information and integrated into the existing geographic information. To minimize the amount of the input by the users, the system relies on the intelligent information technology to construct the graphical structure of the maps and reason about the street conditions.

通信技术、地理信息系统（GIS）和智能信息系统的最新进展对社会技术系统产生了巨大影响。特别是高精度全球定位系统（GPS）新技术使得以合理的成本实时获取移动物体的厘米级定位数据成为可能。本文提出了地理信息系统（GIS）的总体架构，利用互联网和高精度全球定位系统（GPS）协助用户创建无障碍街道地图。该系统的目的是为支持坐轮椅的身体残疾人士创建和使用基于网络的无障碍街道地图提供有效的工具。轮椅配备了GPS天线和平板电脑，以厘米级精度计算当前位置，为街道上的人们导航。服务器收集在本地服务区域内移动的轮椅的位置。采集到的数据转化为有用的无障碍信息并融入现有的地理信息后，在服务器中存储和共享。为了最大限度地减少用户的输入量，系统依靠智能信息技术构建地图的图形结构并推理街道状况。
