Abstract: To auto-change the traffic zone address into traffic zone code in OD survey,a new matching method and computer program were put forward; an object-oriented programming environment ( Visual Basic) and the GIS component ( MapX) as development environment were adopted; zone code matching and its relevant work were achieved through friendly user interface platform and geographical correlation supported by GIS.The results indicated that the system,with the advantage of repeated use and promotion,greatly improved efficiency．

Key words: MapX, origin and destination survey, code matching, traffic zone

摘要： 采用面向对象开发语言(VisualBasic)和GIS组件技术(MapX)相结合的开发环境，通过友好的操作界面平台 和GIS技术支撑的地理相关性完成小区号匹配及相关的工作。结果表明:与传统编码方法相比，此系统自动匹配 大大提高了工作效率，且具有可重复使用和扩展的优点。
